Koso Lock Valve CL420
Koso Retaining Valve CL523
Koso CL420 mainly judges the pressure of air source and is used for interlocking control.
CL523 is mainly connected to the cylinder of the actuator to maintain the position of the actuator. It plays the role of switching, switching and locking in the air circuit.
The lock valve is suitable for important automatic control. In the circuit as a safety protection device.

The lock valve is suitable for important automatic control. In the circuit as a safety protection device.
When the air supply system of the instrument fails, the air lock valve CL420 is used to empty the output side of the lock valve when the air supply pressure is lower than the set value. When the pressure is lower than the set value of cl523, the pressure is detected in time and the channel can be automatically cut off. device. When the compressed air source fails and stops the air supply, the air lock valve is used to cut off the valve control channel, so that the valve position remains the position before the air cut off. In order to ensure the normal progress of the process, the air lock valve will not open the channel until the accident in the system is eliminated and the air supply is re-supplied, and it will be controlled when it returns to normal. (cl420 is used for the main air circuit, cl523 is used for the auxiliary air circuit)
Feature
-Because the product is small in size and light in weight, it can be connected to a metal pipe without a separate bracket.
-It is also sensitive to small pressure difference below 0.1kgf/㎡.
-Adopt epoxy resin coating, good corrosion resistance.
- Limit switches and indicators can also be added to monitor the switch status of the CL420.
