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 material combinations and methods of operation are available depending on the application. The 3/2 way pilot valve can be easily converted from NC to NO functioning principle 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 commissioning and testing. To reduce power consumption in operation, coils with InchKick and DropInch (KD) electronics (double coil technology) are available. In combination with a plug in accordance with DIN EN 175301 - 803 Form A, the valves satisfy protection class IP65 and NEMA 4X.
