This Burkert 2/2 way solenoid valve (Type 142) is designed for controlling the flow of slightly contaminated and aggressive media in applications requiring media separation. Its key benefit is reliable operation with a differential pressure, making it suitable for various industrial processes. A potential caveat is its need for a minimum differential pressure to operate indirectly and that a DIN connector is not included. Key features include a normally closed circuit function (opens with voltage), EPDM sealing, a PVC body, and a manual override.

The valve is suitable for slightly contaminated and aggressive media, thanks to its media separation design and EPDM sealing. Ensure the media is compatible with PVC and EPDM materials and stays within the temperature limit of 50 °C.
No, the DIN connector is not included with this solenoid valve and must be purchased separately.
This is an indirectly operating valve, so it requires a minimum differential pressure of 0.5 bar (7 psi) to open.
Yes, the valve features a manual override function that allows you to operate it without electrical power.
The Kv-value is 6 m³/h, which translates to approximately 100.02 liters per minute at a differential pressure of 1 bar for water.
The maximum media temperature is 50 °C (122 °F).
The valve body is made of PVC, and the sealing material is EPDM.
Verify the 24 V DC power supply to the coil. Ensure there is a sufficient differential pressure (at least 0.5 bar) across the valve. Check for any blockages in the pilot or main orifice. Confirm correct flow direction is maintained.
Inspect the EPDM seals for damage or wear. Ensure the valve is free from debris that may be preventing a complete seal. Check that the operating pressure is within the specified range (0.5 - 6 bar).
Check for obstructions in the valve orifice or the connected piping. Ensure the differential pressure is adequate. Verify that the Kv value of 6 m³/h is not being exceeded by system demand.
Ensure the correct voltage (24 V DC) is applied. Disconnect power immediately and allow the coil to cool. Check for any mechanical binding that keeps the valve energized continuously.
Setup: Ensure the valve is installed in the correct flow direction, indicated by an arrow on the valve body. Connect the 24 V DC coil using an appropriate DIN connector (sold separately). The valve requires a minimum differential pressure of 0.5 bar for proper indirect operation. Ensure the glued sleeves are securely attached to the piping system.
Compatibility: This valve is designed for use with fluids that are compatible with PVC and EPDM materials. It is suitable for slightly contaminated and aggressive media. The operating pressure range is 0.5 to 6 bar, and the media temperature should not exceed 50 °C (122 °F). The coil is rated for 24 V DC.
Care: Regularly inspect the valve for any signs of wear or damage. Clean the exterior with a damp cloth. Avoid using abrasive cleaners or solvents. If the valve is used with fluids that may cause buildup, periodic internal inspection and cleaning might be necessary, following manufacturer guidelines for disassembly and reassembly.
