UNIVERSAL VALVE CORE REMOVER/INSTALLER
With Patented Locking Mechanism for High Pressure Refrigerants
PLEASE USE CAUTION when removing valve cores from a pressurized system!
ALWAYS wear safety glasses and gloves!
VALVE CORE REMOVAL:
7/16”-20 (1/4”FL) Valve Core Connection (Fig. 1A)
1/2-20UNF /Japan Standard Valve Core Connection (Fig. 1B)
1. Turn Valve Lever in the direction of flow so the shaft can go through the body.
2. Connect the valve core to the service port of the system.
3. Push the shaft towards the service port. Slowly and carefully rotate the shaft until the tip of the shaft
engages the body of the valve core.
4. Once the valve core is engaged, turn the locking nut clockwise and screw it on to the shaft connection
nut. This will allow one to remove the valve core without the pressure within the system disengaging the
shaft from the valve core.
NOTE: If the shaft tip does not reach the valve core, turn the locking nut counter-clockwise and
back the shaft out. Then try again.
5. Rotate the shaft counter-clockwise by turning the shaft knob.
WARNING: MAKE SURE THE SHAFT CONNECTION NUT DOES NOT START TOTURN AS YOU ARE
TURNING THE SHAFT. THIS COULD CAUSE THE SHAFTCONNECTION NUT TO LOOSEN AND
REFRIGERANT WOULD LEAK OUT!
6. Continue rotating the shaft knob until you cannot turn the shaft anymore. DO NOT FORCE!
7. Slowly loosen the locking nut from the shaft connection nut.
NOTE: If the valve core is correctly removed, the shaft will automatically travel outward do to the
pressure in the system. If it DOES NOT travel outward, either there is no pressure in the system or
the valve core was not removed.
8. With the shaft pulled out all the way, CLOSE THE VALVE.
(Valve Lever perpendicular to the direction of FLOW)
WARNING: FAILURE TO CLOSE VALVE COULD CAUSE INJURY ANDWOULD RESULT IN A LOSS OF
REFRIGERANT!
9. Loosen and remove the shaft connection nut from the valve body.
10. Remove the damaged valve core.
