China Stainless Steel Valve Balls factory and manufacturers | Xinzhan

Stainless steel is the most common material to be used for the balls of ball valves. We do the inspection strictly for the incoming material to ensure the material is standard. Stainless steel valve ball is produced by modern manufacturing technology of stainless steel and precision machinery. The product can be formed from welded stainless steel plate ( hollow balls ), or integral forged stainless steel ball blank ( solid balls ). Keywords of Stainless Steel Valve Balls Stainless steel valve balls, stainless steel balls for ball valves, SS valve balls, A182 F304 valve balls, stainless steel hollow valve balls, stainless steel solid valve balls, stainless steel balls for valves, T-port 3 way valve balls, L-port 3 way valve balls, V-port valve balls, forged stainless steel valve balls, stainless steel floating valve balls, steel plate welded hollow valve balls. Main Types of XINZHAN Valve Balls - Floating Type: the ball in floating ball valve will have a slight displacement, that is why we call it floating type. As the ball is floating, so under the pressure of the medium, the floating ball will move and against the downstream seat. - Trunnion Mounted Type: the ball in trunnion mounted ball valve wont move because the trunnion ball valve ball has another stem at the bottom to fixed the position of the ball. The trunnion type valve balls are mainly used in high pressure conditions and large sizes ball valves. - Solid Ball: solid ball is machined from compact casting or forging. Solid ball is normally considered as the best lifetime solution. And solid balls are mainly used in high pressure conditions. - Hollow Ball: Hollow ball is made by coil welded steel plate or seamless stainless steel tubes. The hollow ball reduces the load of the spherical surface and the valve seat because of its lighter weight, which helps to extend the service life of the valve seat. For some very large sizes or constructions, solid ball would not be practical. - Soft Seated: soft seated valve balls are used for soft seated ball valves. The seats are typically composed of thermoplastic components like PTFE. These valves are appropriate for applications in which chemical compatibility is crucial, and in situations where having the tightest seal is important. Soft seats, however, aren’t suitable for processing abrasive or high temperature fluids. - Metal Seated: Metal seated valve balls are suitable for applications with elevated temperatures or highly abrasive conditions. Metal Seat and Ball are fabricated from base metals coated with hard chrome, tungsten carbide and Stellite. - Non-standard customized valve balls are also optional! Key Points of valve balls The two most important characteristics of the valve balls are the roundness and the surface finish. The roundness must be controlled especially in the critical sealing area. We are able to manufacture valve balls with extremely high roundness and high surface finish tolerances.
