Overview of VQ647H VQ647H-16 VQ647H-16C VQ647H-16P Pneumatic segment ball valve

VQ647H VQ647H-16 VQ647H-16C VQ647H-16P Pneumatic segment ball valve is a kind of ball valve. Its closing part is a hemispherical body with a V-shaped opening. The V-shaped opening has a sharp edge. During the rotation of the ball, there is a wiping effect between the closing parts, which has a strong cutting force on the medium. The V-shaped opening of the ball and the valve seat channel form a fan-shaped area, which can change the cross-sectional area of the channel during the rotation, It is a kind of angular rotation regulating valve. Its sealing performance is the same as that of ordinary ball valve, so that it has two functions of regulation and switching at the same time. It is matched with pneumatic or electric actuator and is widely used in industrial process automatic control system

Application scope of VQ647H VQ647H-16 VQ647H-16C VQ647H-16P Pneumatic segment ball valve: Energy, petrochemical, metallurgy, chemical industry, mining, papermaking, environmental protection, biochemistry, pharmacy, petroleum, electric power, printing and dyeing, light industry, food, tobacco, sugar, beverage and other fields.

Features of  VQ647H VQ647H-16 VQ647H-16C VQ647H-16P Pneumatic segment ball valve

1. Integral structure of valve body: the valve body of wafer type and flange type V-type ball valve is an integral side mounted structure with strong structural rigidity, which is not easy to cause deformation and leakage.

2. Upper and lower self-lubricating bearings: the valve body is equipped with upper and lower self-lubricating bearings, which have large contact area with the valve stem, high bearing capacity and small friction coefficient, so as to reduce the torque of the valve.

3. Metal hard seal or PTFE soft seal can be selected for the valve seat according to the needs of medium and working conditions: the sealing surface of metal hard seal valve seat is overlaid with cemented carbide, and the spherical surface is plated with hard chromium or spray welding, ion nitriding and other hardening treatments, so as to enhance the service life of the sealing surface and improve the temperature resistance; Soft sealing PTFE valve seat or reinforced PTFE valve seat has good sealing performance, corrosion resistance and wide application range.

4. Economy and practicability: the valve body is light, the valve rod torque is small, and the corresponding specification of pneumatic or electric actuator is small. Compared with other types of regulating valves, it has high cost performance.
