KOSO Pneumatic Lock Up Valve 800kPa 0.14-0.16MPa Ball Structure

KOSO Lock Valve CL-420 Used for shut off, switching, or locking of instrumental air circuit (air relay).

CL-420 air lock valve is a device that can detect the pressure in time and automatically cut off the channel when the air supply pressure is lower than the set pressure. 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.

CL523H is mainly connected to the actuator cylinder, used for actuator position retention, position retention valve
When the air source fails, the output side of the lock valve is emptied when the pressure is lower than the set value of CL420, and when the pressure is lower than the set value of CL523H, if the exhaust port is blocked, it can play a protective role.
Connecting the instrument gas tank to the air port can make the valve fully open or fully closed (CL420 is used for the main gas source circuit, CL523H is used for the auxiliary gas circuit).
CL-420 air lock valve is a device that can detect the pressure in time and automatically cut off the channel when the air supply pressure is lower than the set pressure. When the compressed air source fails and stops the air supply, use the air lock valve to cut off the air supply.
Detach the gate control channel to keep the valve position as it was before the gas cut. In order to ensure the normal progress of the process, the air lock does not open the channel until the accident in the system is eliminated and the air is resupplied.
Return to normal control.
