6. Stem see fit and use have poured tightly closed uninstalling type structure, abnormal booster valve cavity, the valve stem will not be impact. 7. Pneumatic piston actuator sees fit and use of low friction material bearing sleeve, inside the cylinder outer appearance via hard anodic oxygen anti-corrosion treatment, greatly increase the use of the Marine valve cylinder fixed number of year of survival. 。 Q: three chip work principle of the pneumatic ball valve a: 1. When the pneumatic actuators and gas source after connect circuits and systems, air through A pipe tube into A cylinder (A or B B) cylinder Push the piston movement to end, so help and rotating shaft and rotating ball core 90 & amp; 度; 2. Pneumatic actuators at the top of the moving and visual, when green color micro points to remember when the word 'open' micro valve opens. 3. Reply is light green signal valve in the open position when the light is bright, and the red light when the valve in the closed position 4. The locator 5 adjustable valve pipe flow. Seat deem appropriate to use flexible tightly closed structure, is tightly closed good, easy opening and closing.
