Pneumatic three-piece ball valve classification and features: Pneumatic ball valve with O-ball valve and V-ball valve points. O-type ball valve with floating structure, the core is precision castings, the appearance of hard chrome plated, seat made of reinforced PTFE material, the flow channel mouth and the same pipe diameter, flow capacity is extremely large, flow resistance is very small, when closed Leakage, the general use of the switch valve, especially for high viscosity, fiber, granular media; V-type ball valve with a fixed structure, the core opened with a V-shaped incision, proportional control can be achieved, the flow characteristics of similar percentage. Depending on the process equipment can be used pneumatic or electric actuator, respectively, composed of pneumatic ball valve and electric ball valve, pneumatic valve to achieve proportional control to be equipped with valve positioner, electric ball valve to be proportional to be adjusted to be selected electronic electric actuator or Servo amplifier and so on. From the material, can be divided into: carbon steel ball valve, stainless steel 304 ball valve, 316 ball valve and copper ball valve applications can be divided into: high pressure ball valve and low pressure ball valve high pressure pneumatic ball valve: mainly used in petroleum, natural gas, hydraulic oil, construction machinery Low pressure pneumatic valve and other industries: mainly used in media such as corrosive water pipes.
