API 3PC Flanged Trunnion Mounted Ball Valve
Description
The ball of API 3PC trunnion mounted ball valve is fixed, thus it does not move no matter how strong is the pressure. This flanged 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. Commonly, the upper shaft and lower shaft of the ball are equipped with bearings. With small operation torque, API 3PC trunnion mounted ball valve can bear high pressure and large diameter.
Performance
1. Sealing materials can be chosen based on media to increase sealing performance and wear resistance, reducing cost.
2. Our flanged ball valves are guaranteed within 18 months and enjoy lifelong technical service.
3. API 3PC trunnion mounted ball valves can be widely applied in such pipelines as tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, energy systems, etc.
Advantages
1. KERUI has been awarded by ISO9001:2008 international system certification, API 6D certification, CE certification, etc.
2. API 3PC trunnion mounted ball valve is easy to open. It has excellent sealing performance, low friction between sealing surfaces and long service life. The body of this 3PC ball valve is cast in precision, thus it is good in performance. The surface is finished second time, thus it is smooth and bright. The bonnet is processed by numerical control machine.
Components
API 3PC trunnion mounted ball valve is mainly composed of valve body, bonnet, ball, valve stem, valve seat, sealing materials, etc.
