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.

Technical Specification
Design Standard: API6D
Size Range: 2"-60"(DN15-DN1500)
Pressure Rating: ASME CLASS 150-1500(PN16-PN250) 
Body Material: Carbon steel, SS, etc.
End Connection: Butt-welded, Flanged end, etc.
Operation: Manual, Pneumatic, Electric, Electrohydraulic, Pneumatic & Hydraulic, etc.
Temperature Range: -46~200
Fire Safe Design Certificate: Yes, API607, API6FA

Applications
Oil, Gas, Long distance transport pipelines, under-ground services and other industrial applications.

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.
