KOSO CL-523H

The KOSO CL-523H Air Lock Valve is a pneumatic lock valve designed to maintain actuator position in the event of an air supply failure. When the instrument air pressure drops below the preset level, the valve automatically locks the pneumatic circuit, preventing unwanted actuator movement and helping keep the control valve in its last operating position.

Designed for industrial process control systems, the CL-523H is commonly used with diaphragm actuators to provide reliable protection during unexpected air supply interruptions.
