Description

Design Standard Based on API 6D and customer requirements End Connections RF, RTJ as per B16.5 &B16.47 BW, Butt Welded as per B16.25 1) Ball valve with fixed shaft, fully welded structure, only one welding, which can reduce or eliminate leakage. 2) G-type series fully welded ball valve adopts full forging material, it has compact structure with light weight and high strength, maintenance free, and design life can up to 30 years. 3) The bidirectional sealing valve (DBB) allows the venting and discharge of the valve chamber at the fully open and fully closed position. 4) There are two valve seat design: Single piston effect (standard) to provide the valve cavity overpressure self discharge function Double piston effect provides double seal barrier. 5) Low valve torque 6) Valve fire test has API, 6FA, API607 7) Blowout prevention valve stem, anti-blow out stem 8) Anti-static design G-type series full welded ball valves as a kind of emergency shut-off valves are designed for long distance transportation of natural gas or oil products, compressor stops and station and yard distribution station.
