Typical applications

Service reservoirs
Water towers
Break-pressure tanks
Municipal water storage

Approvals

WRASISO 9001

Features

Suitable for service reservoirs where demand varies widely and single-stage control causes water hammer
Opens fully at the low-level set point and throttles to a reduced flow rate as the reservoir approaches the high-level set point, preventing overfill surge and pipeline banging at the end of the fill cycle

Description

The A10B is a bi-level float control configuration of the A900 main valve body, using P10A and P10B float pilots to set independent low-level and high-level control points. The low-level pilot triggers refill; the high-level pilot cuts off supply when the tank is full. The two-pilot arrangement provides a dead-band between fill and cut-off, preventing rapid cycling on reservoirs and break pressure tanks. A float valve switch can be added for alarm or SCADA output.

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.

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

Piping arrangement: main valve, ball valve, P10B bi-level float pilot, strainer, connecting tube. Level range (upper/lower stop) is field-adjustable via the pilot rod stops.

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.
