DIN 3PC Flange Forged Steel Trunnion Mounted Ball Valve

DIN 3PC Flange Forged Steel Trunnion Mounted Ball Valve

Description
DIN 3PC forged steel trunnion mounted ball valve has additional mechanical anchoring of the ball at the top and the bottom, suitable for larger and higher pressure valves. This forged steel ball valve is often combined with floating valve seat, which will move to press the seal ring on the ball under the pressure of media, guaranteeing the sealing performance.

Application
Trunnion mounted ball valve can be widely used in such pipelines as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy systems, etc.

Advantages
1. This forged steel ball valve features excellent sealing performance, low friction between sealing surfaces and long service life.
2. Its surface is finished second time, thus this 3PC ball valve is smooth and bright. The bonnet is processed by numerical control machine.
3. Our trunnion mounted ball valves are guaranteed within 18 months and enjoy lifelong technical service.
