Solenoid Valve for Aggressive and Contaminated Media - 2/2-way - Burkert Type 142

Servo-assisted solenoid valve with diaphragm, normally closed function. Hermetic isolation of fluid from the actuator. A minimum differential pressure of 7 PSI is required to fully open the valve. Valves can be mounted or removed radially for a space-saving installation.

• 20mm up to 63mm sizes.
• PVC or PVDF Body. Non-metallic valve internals.
• Isolating diaphragm between the solenoid and fluid
• Adjustable switching times (waterhammer-free).
• For aggressive media.
• Pivoted armature, with lockable manual override.
• Diaphragm materials:
  • EPDM
  • FKM

The Burkert 142 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 molded with a chemically resistant epoxy.

The 0142 is equipped with manual override for commissioning and testing.

To reduce power consumption in operation, coils with “Kick and Drop” (KD) electronics (double coil technology) are available.

In combination with a cable plug in accordance with DIN EN 175301 – 803 Form A, the valves satisfy protection class IP65 and NEMA 4X.
