Products Related to Fully Welded Ball Valves
reduced fully welded ball valves
Flange full welded ball valve is specially developed according to user requirements; flange full welded ball valve, can be single welding, and it can be on the other side in the flange connection on the other side.
The design of single flange full welded ball valve is piping installation after other valves, which cannot be directly installed all welded ball valve. According to this situation, our factory do the research on the single flange full welded ball valve.The end of the flange can be connected with other valves, or connected with pipe flange; and the other end is connected in welding way, which is convenient to replace the valve flange end.
The structure and design:
flange full welded ball valve is completely designed and manufactured according to the API6D to prevent anti-static and fire. Stem is extended according to the requirements of customers; the body sphere of metal parts are all made of forging high quality materials, to guarantee the quality of the ball valve and intensity. The sphere is fixed with stuffing box or support plate. Stuffing box or support plate fixed ball can eliminate the force from medium in the sphere of the bending moment on the valve stem, so the stem withstand torque. It makes valve movements smooth, switching torque small, and easy to operate. Seal is adopted the unique two soft seal and metal sealing which is formed three sealing. It ensures reliable sealing and the security. It has the advantage of long operating life, and free of maintenance.
