Application fields of pneumatic clamp V-ball valve The service industries include energy, petrochemicals, metallurgy, chemical engineering, mining, papermaking, environmental protection, biochemistry, pharmaceuticals, petroleum, electricity, printing and dyeing, light industry, food, tobacco, sugar production, beverages and other fields. Pneumatic V-type ball valve product features 1. Valve body integral structure: Both clamp type and flange type V-shaped ball valves have 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 a large contact area with the valve stem, high load-bearing capacity, low friction coefficient, and reduce the torque of the valve. 3. The valve seat can be selected as metal hard seal or PTFE soft seal according to the needs of the medium and working conditions: the sealing surface of the metal hard seal valve seat is welded with hard alloy, and the spherical surface is hardened by hard chromium plating or spray welding, ion nitriding, etc., which enhances the service life and temperature resistance of the sealing surface; Soft sealed PTFE valve seats or reinforced PTFE valve seats have good sealing performance, corrosion resistance, and a wide range of applications. 4. Economic practicality: The valve body is lightweight, the valve stem torque is small, and the corresponding specifications for pneumatic or electric actuators are small. Compared with other types of regulating valves, it has high cost-effectiveness. 5. Wide applicability of the medium: Due to the shear force between the V-shaped opening and the valve seat, as well as the smooth and round flow channel in the valve cavity, the medium is not easily accumulated in the cavity. Therefore, in addition to liquid media, it is more suitable for system control with fiber and solid particle media. 6. Small flow precise control: By machining the special V-shaped opening of the small caliber valve core, precise control of the small Cv value can be achieved.
