accordance with the requirements of API 6D for pipeline service.
Anti-static and anti blow-out stem design. Seat design gives
perfect tighness and is available as either self-relieving type or
double piston effect type. Disign minimizes friction leading to low
operating torque. Available as double block and bleed
execution,which allows for venting and draining of ling fluid from
the body cavity. Avaiable Full and Reduced bore. Ball valves
firesafe tested according to BS EN 12266-2,API 6FA and API 607.

connections between body and closure, trunnion bolted connection,
body thickness comply with ANSI B16.34.Seat ring is floating type,
spring loaded to assure the contact with ball in order to provide
an effective tight seal even at low differential pressure between
cavity and downstream closure.Standard design is soft seated. A
different soft seat materials are available based on the customer
working condition.Available in Full and Reduced Bore.Electrical,
pneumatic and hydraulic actuators are available based on customer
requirement.Body Joint Construction Three pieces body end
entry design, graphite ring or o-ring viton (or request) seal
ensure absolute seal integrity. The bolted body designs
include a tight tolerance overlapping metal fit between the body
and the adapter to minimize any possibility of movement due to
pipeline stress. High temperature spiral wound stainless
steel/ grafoil filled gasket is used for absolute seal. Body
and adaptors are dimensioned for metal contact to ensure correct
gasket crush. SpecificationStem Design/Anti BlowoutThe stem is made
separately from the ball,anti blow-up design with.
Anti-Static DeviceAll flow control-floating flange ball
valves include dual grounding systems from stem to ball and stem to
body. Valve testing to BS 5351 and BS 5146 wasperformed
for all sizes, and witnessed by a third party inspectionEmergency
sealant injection Trunnion type ball valves are fitted with
emergency seals to restore. Double Block and BleedBall valves
can be equipped with drain valve which allows the block and bleed
feature when the pressure is simultaneously applied to both sides
of the ball , themedium can be relieved through the drain
valve.Standard design of trunnion mounted ball valves assure that
