4A220-08 Pneumatic Control Valve

A pneumatic control valve, also called a pneumatic pressure regulating valve, is a common pneumatic control device whose main function is to control the pressure, flow, and direction of the air flow to ensure its working performance. The component that controls and regulates compressed air pressure is called an SMG air-source pressure reducing valve. The component that controls and regulates compressed air speed is called a flow control valve. The component that can change and control the direction of air flow is called a directional valve.

The Kuaiyiyou automation selection includes all types of SMC valves, including logic devices with logic functions, including pneumatic logic devices with nozzle devices and movable devices that cannot move within a unit. In structural principle, this logic element is basically the same as a directional control valve, only smaller in size and diameter, and is generally used for logic operations. With the miniaturization of pneumatic components and the popularization of PLCs, its application scope has gradually narrowed.

According to their control method, high-pressure two-position two-way solenoid valves can be divided into intermittent and continuous types. In discontinuous control, pressure regulating valves, flow regulating valves, and directional control valves are usually used in the program; in continuous control, in addition to pressure and flow regulating valves, servo valves and proportional valves should also be used.
