Product Features
• API 6D trunnion mounted ball valve.
• API 6FA Fire safe design.
• 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 KTCLOK for specific application.
• Drain / Vent / Emergency injection / Supporting legs /
Lifting lug are available upon request.
