Product Description

Buna Diaphragm Valve - 230VAC DIN

This normally closed solenoid valve opens once the electrical coil is energized. Once energized, the plunger is pulled to the top plug which opens a small pilot port in the diaphragm plate. Pressure is released on top of the diaphragm allowing incoming pressure to lift it off the large center port.

Use this diaphragm valve for water, air, light oil, noncorrosive, and non-explosive liquids. Its recommended for applications with unfiltered fluid.  This valve has a Buna diaphragm. It's rated for 200 degrees Fahrenheit fluid and 120 degrees Fahrenheit ambient.
