Video introduction

The metal seated high temperature and high pressure forged steel trunnion ball valve designed and developed by the R&D team of Jinhuili is widely used in high temperature and high pressure water, steam, coal, petroleum, chemical, metallurgy, fiber, consistency, paper and corrosive medium, as well as medium with particles and other fields.


This product has the following advantages
1、The body of metal seated forged steel trunnion ball valve is forged by advanced forging process, which can ensure that there is no leakage absolutely.At the same time, the forged body can withstand greater pipeline pressure and pipeline load, and has higher safety.
2、Jinhuili ball valve has high-precision ball processing equipment, the processing cycle of ball is tracked and detected by advanced computer detector, the ball and seat use advanced spray technology.The ball and seat are matched and ground through the treatment of various working conditions, and the whole sealing surface of the ball and seat are precisely matched and ground to the sub-fine surface.The sealing performance and life of the valve can be guaranteed even under frequent operation.
3、IThe preload spring of the seat selects material Inconel X750, which has excellent comprehensive performance, it’s precision of preload and effective stroke of spring are strictly controlled through accurate calculation and wire element analysis.
4、The seat adopts imported seats with DIB-1 bi-directional sealing function, and also the special function of reducing the opening and closing torque, to ensure the sealing performance of the valve and high pressure load opening and closing function.
5、A stuffing box is added at the stem to ensure that it will not fly out under any circumstances, so as to prevent accidents when operating the valve. The stem can be extended according to the customer’s requirements, the stuffing box is designed with multiple seals to further improve the safety of valve operation.
