Side EntryTrunnion Mounted Ball Valve

HW-GWBForged Fully Welded G Type Trunnion Mounted Ball Valve

HW-GWB type ball valve is a high-tech product developed by Hanwei. This type of ball valve is widely on oil & gas pipeline and

liquefied gas, coal gas, etc. as an isolation valve. It adopts unique and

advanced design: the valve body was welded into a whole by two semi-

spheres, ensuring the strength and rigidity and making the valve

with lighter weight, meanwhile eliminates the possibility of medium

leakage; the double floating seats and bi-directional sealing design

adopts unique two layer soft sealing and metal to metal sealing, the

triple sealing structure ensures the reliable sealing performance with

low torque and easy operation. HW-GWB type ball valve has the

characters of long life cycle and free of maintenance.
