The 250 Series of electric air valves are of double diaphragm poppet design. These "no stick" valves require no lubrication, they are ideal for use with instrument air and other media which prohibit lubrication. These valves have no sliding seals subject to cuts or metal seals subject to scratches, so they are ideal for use with contaminating media and are unaffected by compressor varnish. They are designed for rugged duty and rapid cycling and can be mounted in any position.
