HUMPHREY 250 VALVES NPT PORTS

 
 
Humphrey 250 valves 1/4 NPT ports, are of double diaphragm poppet design.  Because these “no stick” valves require no lubrication, they are ideal for use with instrument air and other media which prohibit lubrication.  The use of lubrication, however, will not prevent a 250 Series valve from functioning if the lubricant is varied or removed.
 
250 Series electric air 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.
 
250 Series air valves are 2 position, 2 way, 3 way, single or double solenoid valves.  They are designed for rugged duty and rapid cycling and can be mounted in any position.
