Position valve

Structural characteristics and application scope

The holding valve, also known as the pneumatic locking valve, is an auxiliary component of the pneumatic unit combination instrument. When the gas source system malfunctions, the holding valve can automatically cut off the channel between the regulating instrument and the regulating valve, ensuring that the opening of the regulating valve stops at the position before the malfunction, and enabling the normal operation of the process. After the gas source fault is eliminated, it can automatically resume normal operation. Therefore, the security valve can be used as a safety protection device in the automatic control circuit.
