Features

Suitable for service reservoirs where demand varies widely and single-stage control causes water hammer

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.

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.
