One piece design feature eliminates any Three Piece design is compact and is possible leakage to atmosphere through available with a variety of pipe ends like unnecessary joint faces. screwed, socket weld or butt weld. It is simple for installation and easy for maintenance, and also seats, seals and ball can be replaced quickly without disturbing pipe alignment.

Fire Safe DesignFloating Ball
Trunnion Mounted Ball
In the event of fire, soft insert gets burnt and spring loaded seats ensure metal to metal sealing.
Multiple Stem SealingFloating Ball Trunnion Mounted Ball
Antistatic devices are built in the valve stem to Stuffing gland, Graphite and O-rings arrangement in ensure electrical continuity between ball, stem and stem area prevents leakage to atmosphere. body.
Double Body SealingFloating Ball Trunnion Mounted Ball Double seal combination of O-ring and spiral wound gasket ensure perfect body joint sealing.
Double Block and BleedTrunnion Mounted Ball
Each ball seats shut off the line fluid independently and the upstream and downstream side, allowing double block operation. When the pressure is simultaneously applied to both sides of the ball in closed position, the valve bore and the body cavity will be isolated from each other, and the residue within the body cavity can be released through the drain plug.
Sealant Injection SystemTrunnion Mounted Ball
When the sealing materials (seat sealing or stem O-Ring) are damaged or decomposed by fire or other accidental causes, leakage from the seat and stem can be prevented by injection of sealant into these fittings.
