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.

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 and 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

P10A pilot spring is selected per set-point range: 0.1-0.5 bar (1-5m level), 0.5-1.2 bar (5-12m), 1.0-3.2 bar (10-32m), or 2.2-4.0 bar (22-40m) -- specify the required tank level range at order.

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.
