Features

The A7MD is a pump control valve with an integrated manual override facility and delayed closing function
The manual override allows the valve to be held open or closed independently of pump operation for commissioning, testing and maintenance
The delayed closing timer extends the valve closing time on pump trip, allowing the hydraulic transient to decay before the valve seats, minimising water hammer on long rising mains

Description

The A7MD is a passive pump protection configuration of the A900 main valve body. The hydraulic control circuit slows the valve closing rate on pump stop, preventing the pressure surge associated with rapid check valve slam without requiring a separate power supply or active control system. Closing rate is tuned via needle valves in the pilot circuit. The passive design is inherently fail-safe and suitable for remote or unmanned pump stations.

Selection notes

This control valve is supplied for flanged installation.

Sizes run DN50 to DN800, in PN10, PN16, PN25.

The body is EN-GJS-500-7.

Seat and trim options are AISI 304. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.

Stated service media include clean water and treated water.

It is catalogued for Water & Wastewater.

Working temperature is 10°C to 80°C.

Built to EN 1074-5, BS EN 1074-5, EN 558-1, EN 12266-1 and EN 1092-2.

Supplier remarks

This model uses its own dedicated body (three size-specific parts lists in the source: A90D-Main Valve DN50-150, A70D Main Valve DN200-350, A70D Main Valve DN400-800), the same body as EFC-351 (A76D) -- not the standard A900 body. Accessory set per source: Main Valve, Tube, Needle Valve, Ball Valve, Strainer (no solenoid valve or limit switch -- this is the mechanical/passive variant).

A900 configurations

View full A900 system →

This product is part of the A900 modular system. All configurations share the same hydraulically operated body: the control function is set by the pilot valve(s) attached. An existing A900 body in the field can be reconfigured for a different duty simply by swapping the pilot, without replacing the body.
