The biggest advantage of the Sphere valve balls is that the resistance to the fluid is very small. The area of the sealing surface that is scoured and eroded by the medium is the smallest. The switch operation of the Sphere valve is very easy, the flow direction of the medium is not restricted, the pressure of the medium will not drop, and the medium will not be disturbed. The shape is very simple, and the scale of application is very wide due to its excellent function. The quality of the stainless steel sphere from XINZHAN is stable, and the whole process quality monitoring is implemented, meticulous and comprehensive inspection! Using this product will make your product quality more high-quality and guaranteed!
Types of Sphere valve balls:
Floating or trunnion mounted valve balls, solid or hollow valve balls, soft seated or metal seated valve balls, valve balls with slots or with splines, and other special valve balls in every configuration or modified balls or specification that you can design.
Definition of Main Types of Valve Spheres:
- Floating Type: the Sphere in floating Sphere valve will have a slight displacement, that is why we call it floating type. As the Sphere is floating, so under the pressure of the medium, the floating Sphere will move and against the downstream seat.
- Trunnion Mounted Type: the Sphere in trunnion mounted Sphere valve wont move because the trunnion Sphere valve Sphere 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 Sphere valves.
- Solid Sphere: solid Sphere is machined from compact casting or forging. Solid Sphere is normally considered as the best lifetime solution. And solid balls are mainly used in high pressure conditions.
- Hollow Sphere: Hollow Sphere is made by coil welded steel plate or seamless stainless steel tubes. The hollow Sphere 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 Sphere would not be practical.
- Soft Seated: soft seated valve balls are used for soft seated Sphere 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 Sphere are fabricated from base metals coated with hard chrome, tungsten carbide and Stellite.
