Altitude Control Valve

ZECO Valve Group is established in 1991, as an experienced china valve manufacturer. We have 5 factories in China, which are located in Shanghai, Yancheng and Wenzhou, which mainly manufacture pressure reducing valve, pressure relief valve, balancing valve, PICV, water valveand industrial valves.

Features of Altitude Control Valve

lAutomatic tank fill and shut-off without the use of floats or sensors;

lAccurate shut-off to within inches of set point;

lHigh level point adjustable with single screw;

lExhaust-to-atmosphere operation allows minimum pressure loss.

Altitude Control Valve Working Principle

Altitude control valve closes 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 valvewith a competitive altitude valve pricecontrols the high water level of the reservoir without floats or other devices. It remains fully open until it reaches the closed water level. The altitude valve operationis designed for one-way flow only. The altitude valveis 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.
