The advantages of the pneumatic valve ball butterfly gas characteristics

applicable temperature ℃ or less main advantages:

and seals for fluorine rubber sealing ring,. The pneumatic valve adopts pneumatic valve pneumatic valve before after two seal. So the sealed performance is good.
by pneumatic valve actuator will first in two pieces of the spherical disc horizontal move away from the sealing surface,. In the process of the pneumatic valve in the open. And then rotate ° open the pneumatic valves; Pneumatic valve is closed, two pieces of the spherical disc rotating ° first, and then by the pneumatic valve actuator will he compression in the direction of sealing surface. So the sealing surface is not easy to damage.
to pneumatic valve lumen samyama filled with water,. Inspection line. As a water seal, effectively cut off gas medium, such as gas, to ensure the maintenance personnel life and peace. Mm ~
