1. Valve body integral structure: both the clamp and flanged v-type ball valve body are the overall side loading structure with strong structural rigidity, which can not cause deformation and leakage easily.
2. Upper and lower self-lubricating bearings: the valve body is equipped with a self-lubricating bearing, which has a large contact area with the stem, high bearing capacity, and small friction coefficient, so that the torque of the valve is reduced.
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 range.
4. Economic practicability: the body weight is light, the stem torque is small, and the corresponding specification of pneumatic or electric actuator is small, compared with other types of regulating valves, 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.
6. Precise control of small flow: through the machining of special v-shaped opening of small diameter valve, the small Cv value can be precisely controlled.
