The working principle of three type pneumatic ball valve

. 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 pushing the piston movement to end, so as to drive the rotation axis of rotation and the ball core °
. Pneumatic actuators at the top of the moving and visual, when green signs pointing to 'open' word mark pneumatic valve opens.
. When the reply is light green light pneumatic valve is in open position, pneumatic valve in the closed position when the red light
. Pneumatic valve positioner adjustable pipeline flow
. Pneumatic valve seat adopts the elastic sealing structure, reliable sealing, easy opening and closing.
. Pneumatic valve stem has inverted sealing bottoms type structure, pneumatic valve cavity when the abnormal pressure, pneumatic valve rod will not be impact.
. Pneumatic piston type actuators with low friction materials bearing sleeve, inside the cylinder body outside the hard anodic oxidation of corrosion on the surface, greatly improving the service life of the cylinder.
