Hydraulic Control Valve

Operating Principle of Hydraulic Control Valves:

●Hydraulic control valves consist of a hydraulic dynamic balance system composed of a pressure chamber formed
    by a diaphragm or piston, a valve disc, control piping, needle valves, and pilot valves.

●Preset control functions are achieved through changes in hydraulic pressure.

Valve Opening and Closing Principle:

●Pressure chamber force ＞ pipeline flow force → valve disc closes

●Pressure chamber force ＜ pipeline flow force → valve disc opens

●Pressure chamber force ＝ pipeline flow force → valve disc remains in a balanced, modulating position

Control Method:

●The balanced position of the valve disc can be set and adjusted by operators via the pilot valve.
