Press to adjust the medium parameters selection of valve

In the production process, in order to meet the process requirements of the medium pressure,3 way air valve
 flow and other parameters, the need to install the adjustment mechanism to adjust these parameters. Adjusting mechanism and the operating principle, by changing the flow area between the valve valve disc and valve and valve seat, to achieve the purpose of adjusting the parameters. Such valves are referred to as control valve, which is divided into rely on the power of the medium itself driven called self-driven control valve such as valve, regulator valve, all leading up power-driven (such as electricity, compressed air and liquid power) called his drive control valve, electric control valve, pneumatic control valve and hydraulic control valve.solenoid valve actuator
