Hydraulic control valves is a kind of automatic control water tank, water tower liquid surface of the height of the hydraulic control valves. When the water drop more than the default value, the ball float valve is opened, the piston chamber pressure is reduced, the piston and the pressure difference formation, on the pressure difference under the role of disc open for water supply homework; When the water level rose to the default height, ball float valve is closed, the piston chamber pressure increase the disc close to stop water supply. So reciprocating automatic control liquid surface set in height, realization of automatic water supply function. The product is suitable for use in industrial and mining enterprises, civil construction of all kinds of water tank (pool), water tower automatic water supply system. And can be used as atmospheric boiler circulation water supply control valves. When the pool or a water tower level down inside, ball float valve open drainage, feed line pressure in the valve in water will hold up the pistons, seal face open, the valve is open water supply, when water levels rise to control valves, ball float valve is closed, the piston moves will seal face closed, the valve is to stop the water supply.http://www.sjpec.com/

Hydraulic control valves are basically any type of valve, particularly globe valves that are suited for flow control, that are hydraulically operated to control the valve, i.e., through hydraulic actuation.  Electric and pneumatic actuation is also an option.  In hazardous or corrosive applications, where you would use HF acid monel globe valve, for example, a hydralic globe valve (or control valve) would be highly suitable.
