The model 1600 Altitude Valve is hydraulically operated, diaphragm actuated, control valve that allows flow into the elevated tank in order to maintain the level at the designated maximum. The valve modulates to maintain the tank level. As the reservoir level drops the main valve is open proportionally to increase the filling.

The model 1600 Altitude Valve is hydraulically operated and pilot controlled. The pilot control operates on the differential in forces between a spring load and the water level in the reservoir. The desired high-water level is set by adjusting the spring force.

Operating Principal of ACVs

Valve Closing: When the pilot closes water is trapped inside the bonnet and the main valve disc will be forced to close.

Valve Opening: When the pilot opens water is released from the bonnet allowing the main valve disc to open.

Valve Modulating: The main valve will mimic the small pilot valve. When the latter partially closes the main valve does the same and vice versa. The pilot valve reacts to a change in external signal received from the system. This signal might cause the pilot valve disc to partially close (hence closing the main valve) or to partially open.
