The 0142 valve is a servo-assisted diaphragm valve. A minimum differential

pressure of 0.5 bar is required to open and close the valve. Various diaphragm

materials and circuit functions are available depending on the actual application.

The circuit function fo the 3/2 way pilot valve can be easily converted NC

to NO by rotating it on the main seat. The pilot valve position feedback can

take place with a switching or NAMUR signal. The solenoid coils are moulded

with a chemically resistant epoxy. The 0142 is equipped with manual override

for start-up and testing. To reduce electrical power consumption during operation,

coils with integrated “Kick and Drop” (KD) electronics featuring double

coil technology are available.
