Altitude Control Valve
Features of Altitude Control Valve
Automatic tank fill and shut-off without the use of floats or sensors;
Accurate shut-off to within inches of set point;
High level point adjustable with single screw;
Exhaust-to-atmosphere operation allows minimum pressure loss.
Altitude Control Valve Working Principle
Altitude valvecloses at a preset maximum water level to prevent overflow from an above-ground storage tank or cistern and opens to replenish water when the level of the storage tank or cistern is lowered. Altitude control valve controls the high water level of the reservoir without floats or other devices. It remains fully open until it reaches the closed water level. The valve is designed for one-way flow only. The valve is hydraulically operated with a pilot control. The pilot control operates based on the force difference between the spring load and the water level in the reservoir. The pilot control measures the reservoir head through a customer supplied sensing tube connected directly to the reservoir.
Altitude Control ValveInstallation and Commissioning
In areas where freezing temperatures are possible, the valve should be located in a vault below the frost line. For specific use, please consult Zeco ValveGroup.
