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 pipe the same caliber, great flow resistance, 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 approximately equal 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.
