Buy Area Valve Service Unit (AVSU) in Nigeria.

Where can I buy an AVSU in Nigeria?

Franance’s AVSU category lists three product records from Amico and BeaconMedaes. Use the filtered pages above to identify the exact option you want quoted. The current list includes a valve box, an integrated Medizone configuration and the ZSU2 zone service unit. It does not confirm that the three share the same gas count, alarm, valves, pipe sizes, mounting or site scope.

Provide the department and zone served, approved gas/vacuum schedule, required valve count, pipe sizes and routing, display/alarm plan, drawings, dimensions, mounting type and project delivery location. If replacing equipment, include the existing unit’s manufacturer references and as-fitted information. Ask the quote to separate equipment from any survey, engineering, supply, installation, testing, commissioning, training, spares and maintenance scope. Franance follows up by phone or email after receiving your quotation request; the catalogue is not an online purchase checkout.

What does an area valve service unit do?

An AVSU gives authorised, trained personnel access to the valves that isolate a defined section of a medical gas pipeline. It is part of a wider pipeline arrangement: valve location, service labels, accessible enclosure and any associated pressure monitoring or alarm must match the design and the system records. The boundary and valve schedule must be established by the project’s medical gas design authority, not guessed from the room name or number of beds.

An AVSU is not a medical gas source or manifold. It does not create or regulate the central supply, replace distribution piping, or establish that the gas reaching downstream outlets is correct. It is also not merely a terminal outlet, a general-purpose plumbing ball valve or a standalone alarm panel. Some assemblies combine valves and area alarms; others have ports or provisions for sensors that may require separate components. Identify exactly what the chosen reference includes.

The NHS HTM 02-01 guidance discusses AVSUs as locked boxes containing isolating valves and explains their role in routine and emergency isolation in its UK operational context. Its procedures are not a substitute for the facility’s approved Nigerian arrangements. This guide does not give operating or isolation instructions. Only appropriately authorised staff should access or operate medical gas valves under the facility’s approved procedures.

Which AVSU products are currently listed?

Amico Multiple Zone Valve Box is a project-configured enclosure for multiple shut-off valves. Amico describes security zone indicator panel boxes that can house one to seven zone shut-offs with tube extensions, gauges and a strip of gas labels. Its medical gas pipeline specification also describes multiple-zone assemblies with a selected valve count. Confirm whether the requested Amico box is the security-style or another configuration, the number and sizes of valves, gauge and label schedule, and all first- and second-fix components. The category record does not give one universal model number.

BeaconMedaes Medizone MZ272636 is a named three-gas Medizone configuration with Medipoint 26 local alarm and pressure sensors, according to BeaconMedaes’ Medizone technical datasheet. The datasheet describes the Medizone as a pre-piped, wired and tested module with ZSU2-type area valve units and project-selected pipe positions and connections. It may contain up to six area valve service units; MZ272636 itself identifies a three-gas configuration, not every possible Medizone size or option. Check the exact services, valve units, alarm, pressure sensing, panel height and options on the current configuration schedule.

BeaconMedaes ZSU2 is the manufacturer’s Zone Service Unit. The product page describes gas-specific labelled connections, emergency access, pressure-sensor ports on either side of the valve and surface or concealed mounting. Its specification describes a zone-isolation function and a physical break point for work on a pipeline. The assigned ZSU2 record does not specify a gas schedule, valve count, pipe size, sensor, enclosure or completed Medizone assembly. Request the selected first-fix and second-fix references and confirm all dimensions with current documents.

Buy Amico Multiple Zone Valve Box in Nigeria

The Amico product is a configurable box assembly, not a single universal valve set. Manufacturer documents describe enclosures for one to seven zone shut-offs in the Security Zone Indicator Panel range, and an Amico pipeline-system specification describes multiple-zone valve boxes with a chosen number of shut-off ball valves, tube extensions and gauges. The exact order depends on the valve count, service, size, layout, mounting and project specification.

For a quote, list each medical gas or vacuum service separately, then state the valve size, quantity, inlet and outlet direction, required tube extensions, gauge, service label, panel/enclosure style, lock or security door, mounting and available wall depth. Include the approved drawings and identify whether any alarm or sensor provision is required. Do not assume a gauge or label arrangement shown in a generic brochure is included in the product reference selected for your project.

Ask Amico or the supplier to confirm the exact product reference and drawings for the selected number and size of valves, along with pressure-sensor provisions, if any. The assigned record is for a multiple zone valve box and does not establish an alarm panel, alarm sensors, monitoring, installation, or a completed pipeline segment. Request a bill of materials that separates the box, valves, extensions, gauges, labels and any alarm-related parts.

Buy BeaconMedaes Medizone MZ272636 in Nigeria

BeaconMedaes’ Medizone technical datasheet identifies MZ272636 as a three-gas Medizone with Medipoint 26 alarm and pressure sensors. The document describes a configurable area service module, with gas-specific connections and ZSU2 area valve units; it states that the Medizone assembly is pre-piped, wired and factory tested for installation. These statements refer to the manufacturer’s documented model configuration and do not establish that the quote includes every project option, the site connection, commissioning or Nigerian approval.

The Medizone series supports different gas counts and other configurations without an alarm or with alternate alarm arrangements. Do not substitute a related Medizone reference based on appearance or the family name. Confirm that MZ272636 is the specified selection, identify the three services and valve sizes, and verify the planned pressure sensors and alarm panel. State if an additional central alarm interface, alarm isolation switch, access panel or special panel height is required. Ask the supplier to identify all parts and the exact current datasheet revision in the offer.

The manufacturer schedule uses customer-provided inlet/outlet positions and mounting information. Provide site drawings showing ceiling and finished-floor levels, wall construction, corridor/department location, pipeline routes and required access. Confirm whether the three-gas unit fits the available wall space and whether the selected service and alarm arrangement matches the design. The product listing alone does not establish the dimensions of the project-configured assembly.

Buy BeaconMedaes ZSU2 Zone Service Unit in Nigeria

The ZSU2 is a zone service unit and area valve service-unit option. BeaconMedaes describes it as a gas-specific unit with emergency access and pressure-sensor ports that can support local alarm integration. Surface and concealed mounting are described by the manufacturer. The exact assembly is selected for the applicable service, valve, pipe connections, housing and installation approach; the generic ZSU2 name is not enough to size or order a set.

Ask the supplier to identify the exact first-fix and second-fix parts, valve size, gas-specific shrouds or labels, pipe material and diameter, direction of inlet/outlet, sensor ports, matching alarm equipment, enclosure and mounting. Specify whether this is a standalone ZSU2 order or part of a Medizone module. The latter has a distinct complete assembly and may include pressure sensors and an alarm depending on its model.

BeaconMedaes documentation describes physical isolation and a break point for safe pipeline work. This technical feature is not an instruction for untrained operation. Keep operating procedure, emergency response, permit-to-work, maintenance and alarm response under the facility’s approved medical gas system documentation and authorised personnel.

How do AVSUs differ from alarms, line valves and manifolds?

The AVSU is the access and isolation assembly for a defined area or zone. The valve physically controls that section of the pipeline. An area alarm may be housed alongside the valve or integrated into a module, as documented for Medizone MZ272636, but an alarm alone does not isolate the gas. Pressure-sensor ports alone do not establish that sensors or an alarm panel are included.

A line valve or other isolation valve may serve a different pipeline segment and have different location, access and control requirements. Do not assume a valve-box record is suitable as a substitute for a specified AVSU or that an AVSU can replace all upstream and downstream valves. A central alarm panel monitors designated plant or system conditions; it is not the local valve enclosure. A manifold changes or selects gas source supply; it is not the area isolation unit. See the medical gas alarm system category and medical gas pipeline and bedhead interfaces for related equipment.

Ask the design authority to show every unit, alarm and isolation point on one coordinated drawing. State the point that the AVSU controls and the corresponding alarm arrangement so the offer can be checked against the zone schedule. If a vendor proposes a combined assembly, ask which functions are integrated and which are separate line items.

What drawings and site details should I provide?

Provide the approved medical gas and vacuum schedule, floor plan, riser or schematic, valve/zone schedule and any existing as-fitted drawings. Mark the department served, each gas and vacuum service, the inlet/outlet direction, pipe size and material, proposed mounting location, required valve access and any sensor or alarm connection. Add wall details, finished surface, cavity depth, clearances, ceiling height, nearby doors and services, and the preferred access-panel location.

For Medizone, confirm gas count, alarm configuration, pressure sensor arrangement, inlet/outlet positions, overall panel dimensions and any floor-to-ceiling or high-level access option with the current manufacturer schedule. For ZSU2, provide the exact valve and pipe requirements and whether it is part of an integrated module. For Amico, state the box style, selected valve count/sizes, gauges, labels and dimensions. These requirements are needed to quote the right assembly; they are not claims that a specific configuration is available.

For a refurbishment, identify the live system, existing component references and the work boundary. Have the project engineer determine whether isolations, shutdowns or modifications are planned and who controls them. Do not use a product enquiry to direct work on active pipeline equipment. The medical gas contractor must plan work under the project’s authorised safe-work process.

Which standards and approvals should guide an AVSU project in Nigeria?

ISO 7396-1 covers medical gas pipeline systems and includes requirements related to design, installation, function, performance, testing, commissioning and documentation. ISO lists the 2016 edition as published and confirmed in 2022, with revision work underway. Confirm the edition and amendments required by the project design authority rather than treating a general product listing as proof of conformity.

HTM 02-01 is UK Health Technical Memorandum guidance. Its operational management material describes AVSUs and controlled access in UK facilities. Manufacturer datasheets may describe product configurations against HTM or EN ISO references, but those references do not automatically establish that the unit or installation meets Nigerian project requirements. Ask the owner, engineer and relevant authorities to determine the locally applicable standards, approvals, responsibilities and acceptance documents.

Request current manufacturer specifications, installation drawings, gas-specific parts schedule and any conformity/test documentation required for the project. Check the exact model and intended configuration; an old declaration, brochure or product-family statement may not cover the offered reference or the local project. This guide makes no regulatory approval or compliance declaration for Nigeria.

What should an AVSU quotation include in Nigeria?

Send Franance the facility name, delivery city and state, project contact, room or department, gas/vacuum schedule, valve/zone matrix, approved drawings, required valve sizes and quantities, mounting and finish details, alarm/sensor requirements, target date and existing system references. State whether the requirement is an Amico multi-zone box, Medizone MZ272636, ZSU2, or an approved alternative for design review.

Require the written offer to state manufacturer and exact references, gas services, valve count and size, first-fix and second-fix components, pipe positions and sizes, labels, gauges, alarm and pressure-sensor inclusions, mounting, accessories and exclusions. For Medizone, request the configuration schedule, alarm/sensor details and finished assembly dimensions; for Amico, itemise the box and each valve; for ZSU2, identify the selected service and interface parts.

Ask separately for survey/design review, delivery to the named site, installation, pipeline connections, alarm wiring, testing, commissioning, handover records, training, maintenance and spare parts. Confirm who is responsible for each work package and who witnesses acceptance. Also confirm price, currency, taxes, quote validity, freight, lead time, warranty and local service arrangements in writing. A filtered listing identifies a catalogue record; it does not confirm stock, project suitability or availability of an installation team.

Frequently asked questions about AVSUs in Nigeria

### Does an AVSU include an alarm?

Not always. The BeaconMedaes Medizone MZ272636 datasheet identifies a three-gas unit with Medipoint 26 alarm and pressure sensors. Amico and ZSU2 records are configurable valve-unit or box offers; verify whether alarm hardware, sensors and wiring are included in the exact quotation.

### Is MZ272636 a six-gas Medizone?

No. The manufacturer datasheet identifies MZ272636 as the three-gas Medizone with Medipoint 26 alarm and pressure sensors. Other Medizone references support other gas counts; do not infer them from this model code.

### Is the Amico Multiple Zone Valve Box a single standard configuration?

No. The current category record does not identify one universal configuration. Amico documents boxes with selected valve counts, including a security box that can house one to seven shut-offs. Confirm the exact product style, gas services, valve sizes, labels, gauges and dimensions.

### Can I use HTM 02-01 as proof an AVSU installation is compliant in Nigeria?

No. HTM is UK guidance. The Nigerian project’s design authority and relevant stakeholders must establish applicable local requirements and confirm the installation and acceptance scope.

### Can hospital staff operate the unit based on this guide?

No. This guide is for product selection and quotation preparation, not an operating procedure. Access and operation must follow the facility’s approved medical gas procedures and authorised personnel requirements.
