>> Details:

Kelite trunnion mounted ball valves are manufactured to API 6D specification and tested to API 598/API 607. The construction is side entry two pieces, side entry three pieces, top entry or full welded ball valve. The following are some of the major design features:
1. Fire-safe
All size and pressure valves have been successfully fire-safe tested according to the relevant API and BS specifications. Test certific-ations are available on request.
2. Antistatic
Electrical continuity of all valve components, prevent statics buil-up.
3. Double Block&Bleed
Trunnion mounted ball valve generally use the seat sealing before ball construction. The two seats in the trunnion mounted ball valve can close the inlet and outlet respectively to implement the double block. When the valve is closed, even the both ends have pressure, the cavity and the bore can be blocked. The rest medium in the cavity can be discharged all to the drain plug.
4. Automatically drain plug on body
When the medium in the cavity has physical or chemical changes with the rising of temperature and results in the abnormal increase of cavity pressure. The construction design can push the seat depending on itself to release the pressure to make sure the safety of the valve.
5. Optional: Double piston effect seat
6. Full Bore
Valves have the same bore as the inner bore of the pipeline, convenient for PIG service.
7. Emergency sealing and lubricating sealant
When the seat sealing ring is damaged by accident, we can inject the sealant via sealant emergency injection fittings to avoid the leakage by seat sealing ring.
8. The design of the top flange for actuator
The top flange with yoke and mounting plate is convenient to install the gear, electric and pneumatic actuator.
9. Extended stem for underground
For the valves to be installed underground, the stem can be extended including all the relevant pipes, drain, vent and emergency sealant lines to be attached to the stem extension at the need of the installation or operation.
10. Extended stem for Low temperature
To avoid the valve's packing to be damaged in the low temperature and resulted in the bad sealing, the stem can be extended at the demands.
