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 ball valves components, prevent statics buil-up.
3. Double Block&Bleed
Pipeline ball valve generally use the seat sealing before ball construction. The two seats in the trunnion mounted pipeline ball valve can close the inlet and outlet respectively to implement the double block. When the ball 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 ball valve.
5. Pipeline ball valve Optional:
Soft seal ball valve double piston effect seat
6. Full Bore Pipeline ball valve
Pipeline ball valves have the same bore as the inner bore of the pipeline, convenient for PIG service.
7. Emergency sealing and lubricating sealant
When the pipeline ball valve 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 ball valve actuator.
9. Extended stem for underground
For the API pipeline ball valve 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 trunnion valve's packing to be damaged in the low temperature and resulted in the bad sealing, the stem can be extended at the demands.
