Welded Structure Ball ValveWe make welded structure ball valve with characteristics of has blow-out proof stem, fire safe design, anti-static device, no leakage of valve sealing, low operation torques, double block & bleed (DBB), emergency sealant injection system, stem extension, automatic relief of body cavity (self relieving seat)-standard design, various operation types.
Fully welded structure ball Valve is used mainly in Gas Transmission and Distribution pipeline (Mid-stream), typical for underground and buried installation. This design is also used in many subsea applications, where maintenance activities are not foreseen. The main advantage of this type of Ball Valves are: No leaking paths through the joints. Forged Steel Body assures uniform fine grain structure and toughness free from inevitable casting defects such as porosity, abscess, sand hole, loosen, slag inclusion, crackle, gas hole.     Welded body, butt-welded ends or flanged ends, floating or trunnion mounted design, locking device, extended stem available, full or reduced bore, blowout proof stem, fire safe and anti-static, ASTM A105N, A182 F304, A182 F316, A182 F304L, A182 F316L body material. Mostly of them are used for under ground. This product is also available for hydraulic, pneumatic, electric or gas over oil operated. Please contact us for more information.
