Connect the Air Lines
Clean all lines and connections of dirt, burrs, etc. and
blow them out with clean air before connecting them to
the system. The air supply line (E) should contain an
air filter (N) to remove harmful dirt and moisture from
the compressed air.
Use a normally closed 3-way air solenoid valve (G) to
control the dispensing valve (J). Attach a grounded air
supply line (E) from the 3-way valve to the 1/4
npsm(m) air inlet adapter (7) of the dispensing valve.
See Fig. 1.
