Plug Valves G4E

FLOWSERVE G4 plug valves offer tighter shutoff than other rotary design valves and emissions containment equal to or better than specially designed severe service valves. They are a best choice for difficult chemical applications and for isolation of pumps, tanks, reactors and other critical equipment.

The DURCO G4E plug valve is the DIN/ISO execution of our well-known G4 plug valve.

You can get this valve in a 3-way execution, too: plug valve G4EB.
