Ball Valve Valve Body
We could manufacture all kinds of ball valve body according to our customers' requirements.
Main Description about ball valve
1. Types
Ball valves including Floating ball valves, Trunnion side entry ball valves, Trunnion welded body ball valves, Trunnion top entry ball valves, Double block and bleed, etc...
2. Application
Our valve body are designed and manufactured for a broad range of applications: Oil&gas production,
Oil&gas transmission, oil&gas processing, etc.
3. Materials:
Carbon steels, Austenitic or martensitic SS, Duplex~superduplex SS, Nickel~based alloys, Titanium, Aluminium-bronze and other exotic material. We choose different material according to different types ball valves. E. G. The CRYOGENIC VALVES, whose body and trim material are austenitic SS, because of their ductility at low temperature.
4. Operation:
Manual operated(lever or gearbox depending on valve size), but also equipped with an actuator(electric, pneumatc, hydraulic, gas-over-oil etc. )
5. Valve seats design available in three different versions:
---SPE(single pistion effect): The seat is energized by upstream pressure only.
---DPE(double pistion effect): The seat can be energized by upstream pressure or body cavity pressure.
---DUAL(SPE upstream and DPE downstream): Combining the two seat designs explained above, a double barrier can be assured in case of seat sealing failure.
6. There are three special designs except the standard design(soft seated&lever operated
---CRYOGENIC: Full austenitic stainless steel valve, provided with PCTFE or metal seat, lipseals as static and dynamic seals, stem extension according to BS6364 or as customers request.
---METAL-TO-METAL SEAT: For high temperatures(larger than 250º C) or dirt/slurry service, floating ball valves can be provided with a spring-energized seat, and hard facing on seat and ball contact surfaces.
---STEM EXTENSION: For special applications the operator(lever/gear/actuator)can be lifted by an extension fixed to valve body, and joint coupled to the stem.
---SUBS DEEASIGN: For subsea applications, side entry ball valves are provided with additional seals, blind nuts, subsea actuators etc.
We can meet all the requirements coming from the customer including the need of valves with reduced dimensions and weight. For double block and bleed design, trunnion or floating type, special body design without flanges results in a very short end-to-end dimension. Pipeline bolts shall be screwed into threaded blind holes machined into valve body.
