| When the pneumatic actuator and circuit and system gas source is connected, the air through the pipe A or B tube into the cylinder A (B tank) pushes the piston to the end of the movement, so as to drive the axis of rotation and the ball core rotation by 90 ° 2 pneumatic actuatorThe device linked at the top of the video, when the green sign pointing to the word "open" sign to open the valve. 3 reply control signal light green light valve in the open position, the valve in the closed position when the red light positioning adjustable valves, pipe flow 5. Seat with elastic sealing structure, reliable sealing, easy opening and closing. Stem the use of inverted sealed downloading structure of abnormal pressure of the valve chamber, the stem will not be shocked. Pneumatic piston actuator made of low friction material bearing surface of the cylinder inside and outside, hard anodizing, corrosion treatment, greatly improve the life of the cylinder. |
