ONE. Product Overview

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 turning The formation of accurate adjustment of the medium, it is a kind of angular rotary regulating valve, its sealing performance is the same as ordinary ball valve, so that it has two functions of adjustment and switch at the same time, and pneumatic or electric actuator matching, widely used in industrial process automatic control system.

Two. product performance characteristics

1, body integral structure: wafer type and flanged V-ball valve body is the overall side mounted structure, strong structural rigidity, not easy to cause deformation and leakage.

2, up and down self-lubricating bearings: the valve body is equipped with up and down self-lubricating bearings, large contact area with the stem, high bearing capacity, small friction coefficient, so that the torque of the valve is reduced.

3, valve seat according to the needs of the medium and working conditions, choose metal hard seal or PTFE soft seal: metal hard seal valve seat sealing surface hardfacing hard alloy, ball surface hard chromium plating or spray welding, ion nitriding and other hardening treatment, enhance the service life of the sealing surface, improve the temperature; Soft seal PTFE seat or enhanced PTFE seat good sealing corrosion resistance, a wide range of adaptation.

4, economic and practical: the valve body weight is light, stem torque is small, with pneumatic or electric actuator corresponding specifications are small, compared with other types of regulating valve, cost-effective.

5, the medium is suitable for a wide range: because of the shear force between the V-shaped opening and the valve seat, and the smooth and rounded flow channel in the valve cavity, so that the medium is not easy to accumulate in the inner cavity, so it is suitable for liquid medium, more suitable for fiber and solid material medium system control.

6, small flow accurate control: through the processing of small caliber spool special V-shaped opening, can achieve small Cv value accurate control.
