The metal hard seal forged steel fixed ball valve developed and produced by Wenzhou Jinhuili Valve Company is widely used in high temperature and high pressure water, steam, coal, petroleum, chemical industry, metallurgy, fiber, thickness, papermaking and corrosive media, as well as media with particles and other fields.

1. The valve body is forged by advanced forging process, which can ensure absolutely no leakage. At the same time, the forged valve body can withstand greater pipeline pressure and pipeline load, and has higher safety.

2. The processing process of the ball has advanced computer detector tracking detection, the ball, the valve seat with advanced spraying technology, through a variety of different working conditions, the ball and the valve seat for pairing grinding, the ball, the valve seat the sealing surface is precision with grinding to the surface. Even in the case of frequent operation, can also ensure the sealing performance and service life of the valve.

3. The preloading spring of the seat is made of INCONEL X 750 material with excellent comprehensive performance. After accurate calculation and wired meta analysis of the spring, its preloading accuracy and effective stroke are strictly controlled.

4. The valve seat adopts imported DIB-1 two-way sealing function seat, and has the special function of reducing the opening and closing torque, to ensure the sealing performance of the valve and the high pressure with loading opening and closing function.

5. A packing box is added to the valve stem to ensure that the stem will not fly out in any case, which can prevent accidents during the operation of the valve. The valve stem can be extended according to user requirements, and the packing box uses multiple seal design to further improve the safety of valve operation.

6. The ball valve preset in accordance with ISO5211 and the corresponding standard driving device platform, according to different user requirements at any time to change the driving device, pneumatic, electric, hydraulic, turbine, etc.

7. Metal hard seal forged steel fixed ball valve are designed, tested and accepted according to API6D,GB/T12237 and other standards, in all kinds of harsh working conditions can also be safe, reliable, long cycle, stable operation.
