The central body 

connects material, air and electrical 

signals from the solenoid valves. Two parallel channels 
supply material up to the nozzle head. A third channel is 
provided for the material return flow back to the swivel 
housing.

A needle guide (N) is located at the front end of the cen-
tral body (H) to align the needle valves with the valve 
seats in the nozzle head. The nozzle head gasket (L) 
seals between the material supply and the nozzle head 
(D). The two nozzle head locating pins (M) ensure that 
the nozzle head is always mounted in the correct posi-
tion. The valve needles packing set (O) seals off the 
valve needles from material and air pressure.
