Classification And Characteristics Of Stainless Steel Pneumatic Ball Valves

Pneumatic ball valves are divided into O-type ball valves and V-type ball valves. The O-type ball valve adopts a floating structure, the ball core is precision casting, and the surface is hard chromium plated. The valve seat is made of reinforced polytetrafluoroethylene. The flow port is the same diameter as the pipe. It has a large flow capacity, a very small flow resistance, and no flow resistance when closed. Leakage, generally used as on-off valve, especially suitable for high viscosity, fiber-containing, granular media; V-shaped ball valve adopts a fixed structure, with a V-shaped cutout on the ball core, which can achieve proportional adjustment, and the flow characteristics are approximately equal percentages. Depending on the process equipment, pneumatic or electric actuators can be selected to form pneumatic ball valves and electric ball valves respectively. The pneumatic ball valve must be equipped with a valve positioner to achieve proportional adjustment. The electric ball valve must be equipped with an electronic electric actuator or an electric actuator to achieve proportional adjustment. Servo amplifier, etc.
