Plug Valves G4
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.
