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.

Servo-assisted diaphragm valve up to DN50
Plastic valve for aggressive and contaminated media
Media separated, metal-free version
Service-friendly manual override
Switching reliability with feedback function (available as an option)
