API 2PC Flanged Trunnion Mounted Ball Valve
Description
The ball of API 2PC 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.
Application
API 2PC flanged ball valves 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. API 2PC flanged ball valve is easy to open. It has excellent sealing performance, low friction between sealing surfaces and long service life.
2. The body of this trunnion mounted ball valve is cast in precision. Thus it is good in performance.
3. The surface is finished second time, thus it is smooth and bright. The bonnet is processed by numerical control machine.
4. KERUI has been awarded by ISO9001:2008 international system certification, API 6D certification, CE certification, etc.
5. Sealing materials can be chosen based on media to increase sealing performance and wear resistance, reducing cost.
6. Our trunnion mounted ball valves are guaranteed within 18 months and enjoy lifelong technical service.
Components
API 2PC flanged ball valve is composed of valve body, bonnet, ball, valve stem, valve seat, sealing materials, etc.
