Stainless Steel Fixed Ball Valve

Compared with the floating ball valve, the force produced by the fluid pressure in front of the valve on the ball is all transferred to the bearing, so the ball will not move to the valve seat, so the valve seat will not bear too much pressure; Moreover, the Stainless steel fixed ball valve has small torque, small deformation of valve seat, stable sealing performance and long service life, which is suitable for high pressure and large diameter applications.

3.Features of Stainless Steel Fixed Ball Valve

1) Stainless steel fixed ball valve has two-piece and three piece valve body structures. The middle flange is connected by bolts, and the seal is made of reinforced polytetrafluoroethylene inlaid into the stainless steel ring. There is no spring at the back of the steel ring to ensure that the valve seat is close to the ball and keep the seal.
2) There is no PTFE bearing on the upper and lower valve stems of the Stainless steel fixed ball valve, which reduces friction and saves labor. There is no adjusting plate at the bottom of the small shaft to ensure the joint position between the ball and the sealing ring. Full bore design for pipeline cleaning.
3) Stainless steel fixed ball valve automatic pressure relief function: when the stagnant medium pressure in the valve cavity rises abnormally and exceeds the preload of the spring, the valve seat will retreat from the ball to achieve the effect of automatic pressure relief, and the valve seat will reset automatically after pressure relief.
4) Stainless steel fixed ball valvedrain pipeline: the drain valve L is set up above and below the valve body to check whether the valve seat leaks. During operation, when the valve is fully open or closed, the pressure in the middle chamber can be removed and the packing can be directly replaced; Can be discharged in the cavity retention, reduce the pollution of the medium to the valve. Auxiliary seal setting system;
