0290 2/2-Way Diaphragm Solenoid Valve

Brand: Burkert Fluid Control Systems
Does not ship to United States

The 0290 valve is a servo-assisted solenoid valve of the S.EV series. The valve opens without differential pressure.

The opening process is supported by the fixed coupling of the diaphragm to the plunger. In the process, the integrated soft-kick function opens in a manner that is gentle on the material.

Various diaphragm material combinations are available depending on the application. The housing offered is rounded out by a stainless steel and grey cast iron version. The solenoid coils are moulded with a chemically resistant epoxy.

Kick and drop electronics are moulded into all DC variants for reduced electrical power consumption.

In combination with a plug in accordance with DIN EN 17301-803 Form A, the valves satisfy protection class IP65 - in combination with a stainless steel housing NEMA 4X.
