Features

  • The A10A altitude control valve fills elevated storage tanks and water towers by sensing the hydrostatic pressure at the tank connection
  • When the tank reaches the high-level set point, the pilot closes the main valve; when the level drops to the low set point, it reopens
  • Fully hydraulic operation — no electrical power or float mechanism inside the tank is required

Description

The A10A is an altitude control configuration of the A900 main valve body, fitted with a P800 altitude pilot. The pilot derives the water level in an elevated tank or tower from the hydrostatic pressure at the base connection: when the tank is full the pilot closes the main valve; when level drops to the low set point it reopens. Fully hydraulic operation requires no electrical power and no float mechanism inside the structure. A float valve switch accessory can be added for high-level alarm or SCADA telemetry.

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.
