HUMPHREY 42E1 TAC3 VALVES NPT PORTS
Humphrey 42E1, TAC3 valves NPT ports, feature Delrin sleeve construction to reduce friction for smooth performance and long service life. Single-solenoid models employ a mechanical spring and a patented air spring to return the main stem. Double solenoid models maintain the last position automatically, preventing equipment damage when pressure is interrupted. TAC3 electric air valves are a series of rugged, compact, 2 position, 4 way, 5 port valves having a common inlet and separate exhausts. Cylinder port #1 is normally open; cylinder port #2 is normally closed. They have a non locking manual override. The valve cover serves as a junction box for easy wiring and can be removed without disconnecting the wiring.
