Features

The A206 adds a solenoid pilot to the A200 pressure reducing configuration, enabling remote open/close control
Under normal operation the valve reduces downstream pressure to the pilot set point
On solenoid energisation, the valve is driven fully closed to isolate supply independently of the PRV function
Used in SCADA-controlled networks where emergency isolation or scheduled off-supply is required at pressure-reducing stations

Description

The A206 adds a solenoid pilot to the A200 pressure reducing configuration of the A900 main valve body. Under normal operation the P200 pilot reduces downstream pressure to the set point. On solenoid energisation the valve is driven fully closed to isolate supply independently of the PRV function. Used in SCADA-controlled networks where emergency isolation or scheduled off-supply is required at pressure reducing stations. An on/off accelerator can be added to increase closure speed.

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 Stainless Steel AISI 304 and Stainless Steel AISI 316. The seat, not the body, usually sets the temperature and medium limit, so confirm it against the service before ordering.

Stated service media include water.

It is catalogued for Water & Wastewater.

Working temperature is -10°C to 80°C.

Built to EN 1074-5, BS EN 1074-5, BS EN 558-1, ISO 5208 and BS EN 12266-1.

Supplier remarks

Control loop (per source parts table): Main Valve (GJS 500-7), Needle Valve, Pressure Reducing Pilot, Ball Valve, Strainer and Solenoid Control Pilot all SUS304, connected by tube. The solenoid control pilot is a bought-in third-party component (source names a specific brand for it; not reproduced here per the no-supplier-names-in-buyer-facing-content rule -- see internal source PDF).

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.
