3PC Design Body Full Bore Casting Trunnion Mounted Ball Valve

• API 6D trunnion mounted ball valve.

• ISO 5211 mounted pad design for actuator application.

• Double block and bleed design, single valve with two seating surfaces that, in the closed position,  provides a seal against pressure from both ends of the valve with a means of bleeding the cavity  between the seating surfaces. And single piston  effect seats design, as known as self-relieving  seats, permits the automatic release of nay over  pressure in the body cavity when the valve is in  the fully open or fully closed position.

• Emergency sealant injection which provide an  effective temporary solution for minor leakage  problems. Sealant can be injected directly to the  stem sealing area and seat  sealing area to affect  a temporary emergency seal in the event of the  stem seal or seat seal is dmaaged. Valves would be   complete with emergency sealant injection over 6".

• API 607 fire safe design. In case of fire during the use of valve, the seat ring, stem O-ring and middle flange  O-ring made of PTFE, rubber or other non-metal   materials will be decomposed or damaged under high   temperature. Under pressure of the media, the ball   itself will push the seat retainer rapidly towards the  ball and make the metal to metal sealing structure,  which can effectively control valve leakage.

• Other flange drilling standards (EN1092, AS2129,  BS10, etc.) are available upon request.

• Variety of material is available upon request, please  consult Terofox for specific application.

• Drain / Vent / Emergency injection / Supporting legs /Lifting lug are available upon request.

• NACE MR0175 / MR0103 are available upon request
