Product Introduction of Compact Electric Flanged Ball Valve The V-type flanged ball valve is a type of ball valve. Its closing member is a hemispherical body with a V-shaped opening. The V-shaped opening has a sharp shearing edge. During the rotation of the ball, the wiping action between the closure members provides strong cutting force for the medium. The V-shaped opening of the ball and the valve seat flow path form a sector-shaped area. During rotation, the flow passage cross-section can be changed, enabling precise regulation of the medium. It is an angular rotary control valve, and its sealing performance is comparable to that of ordinary ball valves, giving it both regulating and on-off functions. When paired with a pneumatic or electric actuator, it is widely used in industrial process automation control systems. Product Features of Compact Pneumatic Wafer Ball Valve 1.Integral valve body structure. Both the wafer and flanged types feature an integrally side-mounted body design. This offers high structural rigidity, effectively preventing deformation and external leakage. 2.Self-lubricating bearings (top and bottom). The valve is equipped with self-lubricating bearings at both the top and bottom of the shaft. These provide a large contact area with the valve stem, resulting in high load-bearing capacity, low friction coefficients, and reduced valve operating torque. 3.Versatile seating options (metal hard seal or PTFE soft seal). Depending on the medium and operating conditions, the valve seat can be selected as either a metal hard seal or a PTFE soft seal. The metal hard seal seat features a hardfaced sealing surface (alloy overlay), while the ball surface is hardened via chrome plating, spray welding, or ion nitriding. This significantly extends sealing face life and increases temperature resistance. The PTFE or reinforced PTFE soft seal seat offers excellent sealing performance and corrosion resistance, adapting to a wide range of applications. 4.Cost-effectiveness. The valve body is lightweight with low stem torque, allowing for a smaller-sized pneumatic or electric actuator compared to other control valve types. This provides a high cost-performance ratio. 5.Broad media adaptability. Due to the shearing action between the V-shaped opening and the valve seat, combined with the smooth, rounded internal flow path, media accumulation within the valve cavity is minimized. Therefore, besides liquids, it is particularly suitable for systems containing fibrous materials or solid particulate matter. 6.Precise low-flow control. By implementing specialized V-shaped notch machining on small-bore valve cores, precise control at low Cv (flow coefficient) values is achieved.
