Double acting or Spring Return On Off Ball Valve with Pneumatic Actuator

  • The resistance coefficient of the fluid is equal to that of the same length of pipe
  • Simple structure, small volume and light weight, high torque
  • It is tight and reliable. The sealing surface material of ball valve is widely used in plastic, with good sealing performance. It has also been widely used in vacuum system
  • It is easy to operate and fast to open and close. It only needs to rotate 90 ° from full open to full close, which is convenient for remote control
  • It has a wide range of applications, ranging from small diameter to several millimeters and large diameter to several meters, from high vacuum to high pressure
