Tips: Basic composition of pneumatic valve actuators
The type and structure of the adjustment mechanism of the pneumatic valve actuator are roughly the same, but the main difference is the actuator. Therefore, the pneumatic actuator is divided into two parts: the actuator and the regulating valve. Pneumatic actuator consists of two parts: actuator and regulating valve (regulating mechanism). According to the size of the control signal, the corresponding thrust is generated to push the regulating valve to act. The regulating valve is the regulating part of the pneumatic actuator. Under the action of the thrust of the actuator, the regulating valve produces a certain displacement or rotation angle to directly regulate the flow of the fluid.
