5. Adjustment
The necessary settings of the transfer valve are generally performed at the factory and adjustment of
it is not required. If, however, the setting pressure needs to be adjusted, make adjustment as follows:
a) Loosen the lock screw (23) and turn the adjust knob (14) counterclockwise to release the
compression of the spring (22).
b) Turn the adjust knob (14) one or two turns clockwise to tighten it and to slightly compress the
spring (22).
c) Connect air pressure to “IN” marked on the body to check whether the body is open or closed.
Then connect the pressure gauge and pressure reducing valve to the signal pressure connection
port SIG.
d) Apply supply air pressure and set the air pressure to SIG at specified pressure by operating the
pressure reducing valve while watching air pressure to SIG on the pressure gauge.
e) Turn the adjust knob (14) clockwise until air pressure no longer leaks through “OUT” marked on
the body.
f) This will cut off IN, and OUT and EXH will open in the transfer valve.
g) Lastly, fasten the lock screw (23) and fix it.
The ball (18) temporarily floats to transfer the pilot part and the valve emits a light beat tone
when the set and signal pressures become the same. This is not an anomaly. The beating
sound will stop when the transfer ends.
6. Maintenance
Rubber is used in various parts of the transfer valve. Periodical exchange of this rubber every five
years is recommended. Your valve will be checked and repaired at our factory if a check or a repair
becomes necessary. Contact our agent or sales office for a check or a repair.
