7.1 Procedure for Switching Action (Reverse Action ↔ Direct Action)
Disassemble the valve body and actuator by referring to the procedure described in Section 5.2. Change the
ball direction to the desired action, and connect the solenoid valve and accessories. Then perform a
recalibration.
1. Check the air pressure supplied to the valve and then check the condition
of the filter regulator.
2. Check the operations of parts such as solenoid valve and air operated
valve.
3. Disassemble the valve and check whether there are any foreign
substances in the ball and seat.
4. Check the design temperature and actual line temperature.
5. Remove the actuator and try to operate the actuator only.
1. Check the air pressure supplied to the valve.
2. Check the voltage of the solenoid valve.
3. Apply the correct air pressure to the actuator to see whether it works
properly or leaks. (If it leaks, fasten the cylinder cover bolts.)
1. Check pressure at the entrance and exit of the valve.
2. Visually check whether the valve responds to signals.
3. Check whether the valve operates with the maximum stroke.
