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.
