Altitude Pilot Control Valves

Altitude Pilot Control Valve

What is altitude pilot control valve?

A control valve that is actuated by a highly sensitive altitude pilot, located outside the tank. The pilot valve opens or closes the main valve in response to the static pressure of the water.

How level control valve works?

Altitude Valve is a hydraulic, diaphragm-type, pilot operated, used to manage the filling of water elevated tanks and resorvoirs by means of a mechanical float that operates a pilot valve to control the main valve. It typically opens in response to a 1m or 0.5m level drop. The pilot valve opens or closes the main valve according to the static pressure of the water sensed in the pilot system.

When the tank is full, the pilot valve shuts the main valve and stops the water flow. Once the level drops again, the pilot valve opens which in turns open the main valve until the float is again level and both the pilot and main valves close.

Description
