Technical Specification
Design Standard: API6D
Size Range: 2"-60" (DN50-DN1500)
End Connection: FLNG, BW, etc.
Body Material: Carbon steel, SS, etc.
Product Introduction
The fully welded trunnion mounted ball valves are
designed according to API6D standard, transition & pup pieces could to
match line grade if needed, available with stem extension for buried
installation. These valves are usually applied in wide temperature ranges, particularly
for pipeline flow with large size and high pressure. The valves are fire safe
designed and have been certified per API607 and API6FA.

Product
Features
1. Blow-out proof stem internally inserted which
functions as the backseat for assuring stem sealing at all pressure.
2. Emergency sealant injection fitting to prevent
leakage from stem and seats.
3. Welded construction to eliminate external
leakage through the connect of body and closures.
4. Secondary metal-to-metal sealing ensure
shutting off the line fluid when non-metal sealing is deteriorated by fire.
5. Loaded floating spring energized seat ensure
sealing even at low pressure.
Compare to flange split body trunnion mounted
ball valves, fully welded body valves eliminate the possibility of leakage
through the body connection. The fully welded body design is compact, cost
efficient and provides maximum strength and resistance to pipeline pressures
and stresses. In order to avoid internal damage cased by heat transfer during
installation/welding, the valves are designed with extended weld ends.
Routine
Maintenance
An indispensable means for valve optima
performance, includes:
-Check the tightness of bolts and nuts
-Check the sales of stem, body and cap on daily
basis
-Check valve corrosion.
