title
In comparison to the conventionally austenitic stainless steel grades, the forged duplex stainless steel trunnion mounted ball valve have a much higher tensile strength. The combination of good mechanical properties in combination with good weldability is the reason why 2205 Duplex Ball Valves can be used in an as welded condition. Material Specifications Body/bonnet: […]

Trunnion mounted twin Ball DBB valve
Trunnion mounted twin Ball DBB valve has a single body design with double balls with a bleed valve (normally we use a needle valve or globe valve) installed between the pipeline. Twin Ball DBB valves are available bi-directional in metal seated and soft seated style, in bubble tight shut off. Sometimes we also called twin […]
API6D fully welded ball valve
API6D fully welded ball valve is trunnion mounted. High-strength forged stems are located in PTfE impregnated stainless steels bearings for smooth operation. Trunnion mounted stems absorb the thrust from line pressure, preventing excess friction between the ball and seats, so even at full rated working pressure, operating torque stays low. Main features All-welded […]
API 6D Forged top entry trunnion mounted ball valve
API6D Forged top entry trunnion mounted ball valves are generally manufactured with the features of double block and bleed (DBB), cavity relief, bi-directional, fire safe and secondary metal to metal seated etc. The DBB design can block both upstream and downstream media. And when the pressure in the middle cavity is greater than the seat […]
