Operating media

Water

Typical applications

  • Elevated storage tanks
  • Limited capacity supply mains
  • Water towers
  • Rural water supply

Approvals

WRASISO 9001

Features

  • The A14A combines altitude level control with a rate of flow limiter in a single valve
  • The altitude pilot closes the valve when the tank is full; the flow pilot limits the fill rate to protect the supply main during peak demand
  • This combination prevents over-demand from elevated storage while maintaining full altitude control
  • Used at elevated tank inlets where the supply main has limited spare capacity

Description

The A14A combines altitude level control with rate of flow limiting in a single A900 valve body, using a P800 altitude pilot and P400 flow pilot in tandem. The altitude pilot closes the valve when the tank is full; the flow pilot limits fill rate to protect the supply main during peak demand periods. This combination prevents both over-demand from elevated storage and tank overflow. An Alpine orifice plate provides the differential pressure signal for the flow pilot. Used at elevated tank inlets where supply main capacity is constrained.

Selection notes

This control valve is supplied for flanged installation.

Sizes run DN50 to DN1000, 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.

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.
