FLOWSERVE DURCO 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.
If you need this plug valve as 3-way execution, please check plug valve MG4.
