Tips: Pneumatic valve actuator performance

1. Under the air pressure of 0.6MPa, the output torque or thrust in the opening and closing directions of the pneumatic device should not be less than the value indicated on the pneumatic device plate, and the action should be flexible, and permanent deformation of each part is not allowed.
2. When the maximum working pressure is used for the sealing test, the amount of air leaking from the back pressure side is not allowed to exceed (3+0.15D) cm3/min (standard state); The air volume is not allowed to exceed (3+0.15d) cm3/min.
3. The strength test is carried out with 1.5 times the maximum working pressure. After maintaining the test pressure for 3 minutes, the cylinder end cover and static sealing parts are not allowed to have leakage and structural deformation.
4. The number of action life times, the pneumatic device simulates the action of the pneumatic valve. Under the condition of maintaining the output torque or thrust capacity in both directions, the opening and closing times of the opening and closing operation should not be less than 50,000 times (the opening-closing cycle is one time).
5. For the pneumatic device with buffer mechanism, when the piston moves to the end position of the stroke, no impact phenomenon is allowed.
