Adjust the pneumatic valve and single cylinder double cylinder adjust the difference between the pneumatic valve < / div >

what circumstances choose single cylinder control pneumatic valve, what circumstances choose double cylinder function of regulating pneumatic valve?

not all pneumatic valve is single-acting pneumatic regulation in general pneumatic diaphragm regulating pneumatic valve of straight travel is single-acting have large diameter straight stroke regulating pneumatic valve adopts the cylinder actuators have double-acting price is more expensive but less single-acting pneumatic valve depends on double-acting pneumatic valve failure of pneumatic valve position of failure for pneumatic valves are pneumatic valve pneumatic valve to open or close the pneumatic valve is single-acting pneumatic valve fault is a single action of pneumatic valve clearance breakdown of positive role is a single action require a backlash if the failure of pneumatic valve is any position then pneumatic valve is dual role of the difference of single and double action was double-acting actuators have spring is not spring price will be cheaper
