The structure and working principle of hydraulic pneumatic control valve

the structure and working principle of pneumatic valve hydraulic control

any kind of hydraulic pneumatic control valve actuator is a kind of using energy to drive the pneumatic device of the valve. Hydraulic pneumatic valve control device that may be related to the human operating gear set, hydraulic pneumatic valve, pneumatic valve to switch control or is a complicated intelligent control and measurement device with electronic components, use it can achieve continuous adjustment of pneumatic valve. With the development of microelectronics technology, hydraulic pneumatic control valve actuators becomes more complicated. Early actuator is only a motor with position sensing switch gear. Today's actuators have more advanced features, hydraulic pneumatic control valve not only can open or close the pneumatic valve and can detect the working state of the pneumatic valve and actuator provide various data for predictive maintenance.

hydraulic pneumatic control valve for executing agency is the most widely definition: a kind of can provide device driven by linear or rotary motion, it USES some kind of drive energy and work under the action of a control signal. Hydraulic control pneumatic valve actuator using liquid, gas, electricity or other energy and through the motor, cylinder or other device to convert it to drive. Basic is used to control the hydraulic pneumatic valve actuator pneumatic valve actuation to the fully open or close position.
