Hydraulic Control Valves
Hydraulic Control Valve is operated hydraulically, designed to move by driving pressure difference beeween upside chamber and downside chamber which are caused by diaphragm or piston in valve. The diaphragm or piston divides the actuator into two distinct pressure chambers, and the control system list are also including disc, cock, tube, spring, needle valve and pilot valve. Whenever the upside diaphragm chamber exceeds to the downside chamber in force（caused by pipeline pressure）,the disc is enforced to close. Otherwise the disc is opened by pressure of downside chamber, pipeline system maintainers are able to operate the valve by driving the pilot valve and setting pressure balance of both pressure chambers, which could make the valve to be used in a wide range of applications.
