Connection between pneumatic valve and solenoid valve

Of course, the solenoid valve can be used to control the pneumatic valve, but the solenoid valve can only be opened/closed and cannot be adjusted.

On-off valves are generally controlled by solenoid valves. According to customer's requirements, if there is a positioner, the adjustable type is not equipped with a solenoid valve, while others are equipped with both a solenoid valve and a positioner.

The solenoid valve is a part of the whole system. The solenoid valve can only work when the air source is connected. Of course, solenoid valves can also be divided into many types, including NC type, NO type, pilot type and direct type.

Pneumatic valve means that the action of the valve needs air as the power source. At this time, an electric actuator is needed to drive the valve, and the solenoid valve is used to control the switch of the pneumatic actuator, so as to control the valve switch.

One of the simplest gas path systems includes filter pressure reducing valve, solenoid valve, pneumatic actuators and pneumatic valve. For different requirements, more accessories can be added to meet the corresponding requirements.
