V ball valve overview

Updated: 2017年07月16日

V type ball valve is a kind of ball valve, it shut down a is half sphere has a V opening, v-shaped opening has a sharp edge, in the process of rotating sphere, wiping, between the closed to the media has a strong cutting force, the sphere of v-shaped opening port to form a fan-shaped area, with the valve seat can change the port area, in the process of rotary forming of medium precision adjustment, it is a kind of Angle of rotation of the regulator, the same as the common ball valve sealing, make it have a combination of regulation and switch two functions, equipped with pneumatic or electric actuators, widely used in industrial process control system.

V ball valve product features

1. Body integral structure of valve body: both the dual and flange V ball valve bodies are integral side loading structure with strong structure and not easy to cause deformation and leakage.
2. Self-lubricated bearing: the valve body is equipped with self-lubricated bearing, which has a large contact area with the stem, high carrying capacity and small friction coefficient, which reduces the torque of the valve. A detailed explanation of V ball valve
3, seat can be according to the needs of medium and conditions, choose metal hard seal or PTFE soft seal: carbide surfacing metal hard seal seat sealing surface and the ball surface hard chromium plated or spray welding, ion nitriding, such as hardening treatment, the service life of the sealing surface, enhance heat resistance increase; Soft sealing PTFE seat or enhanced PTFE seat sealing is good for corrosion resistance and wide adaptation.
4. Economic practicability: the body weight is light, the stem torque is small, the corresponding specification is small for the pneumatic or electric actuator, compared with other types of regulating valve, the cost performance is high.
5, medium adaptation range: because the shear force between the v-shaped opening and valve seat, and in the valve cavity flow smooth and rounded, the medium is not easy to accumulate in the inner chamber, so it except for the liquid medium, more suitable for fiber and solid material medium system control.
