Product Name: Hollow Valve Balls

Specification:

The hollow ball reduces the load of the spherical surface and the valve seat because of its lighter weight to extend the service life of the valve. Hollow valve balls can be also make floating type or trunnion mounted type, two way or multi-way type. 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.
