Working principle of pneumatic valve

The working principle of the pneumatic valve is to control the compressed air through the control system to make the actuator switch action. When the compressed air enters the cylinder of the actuator, the piston moves downward under pressure, driving the connecting rod to make the valve disc switch action. At the same time, the control system can precisely control the opening speed and position of the valve by adjusting the opening and time of the intake and exhaust ports.

Pneumatic ball valve is a valve that uses compressed air as a power source and drives the ball to rotate through the pneumatic actuator to control the flow of the medium. It has the characteristics of simple structure, easy operation, reliable sealing, quick opening and closing, etc., and can maintain good performance in various harsh working environments.

Pneumatic control valve

Pneumatic control valve is one of the commonly used actuators in the field of industrial automation control, mainly used to adjust the flow, pressure, temperature and other parameters of the pipeline medium. It takes compressed air as the power source, and realizes the opening and closing of the valve through the cylinder, slide valve and other mechanisms, so as to achieve the control of the medium quality of the pipeline.

Pneumatic 3 way control valve is a kind of valve that uses compressed air as power source and regulates the pressure, flow rate, temperature and other process parameters of fluid medium (such as gas and liquid) by controlling the opening of the spool. It is usually composed of a multi-spring pneumatic film actuator and a three-way combination (shunt) valve with a cylindrical thin wall window spool, which has the characteristics of compact structure, light weight, sensitive action and accurate flow characteristics.
