ZPB-12 Lock valve

Overview

ZPB-12 Lock valve is one of the actuator accessories, it is used in conjunction with a pneumatic membrane actuator or a two-way piston pneumatic actuator. When the air source system fails, it can automatically cut off the air intake and exhaust passages of the pneumatic actuator to keep it in the position at the time of the accident to ensure the normal progress of the process. When the air source accident is eliminated, the retaining valve can automatically resume normal operation. Therefore, the pneumatic retaining valve is used as a safety protection instrument in an important automatic control loop.
