Description
Choose a 3/2-way valve for a single acting cylinder with a spring return, which requires a single action to extend. After the spring retracts the valve rod, the valve returns to its normal, unactuated position. Pneumatic roller lever valves with idle return are activated by the cam of a cylinder traversing the lever in a certain direction. A return spring returns the valve to its initial position after the roller lever has been released.
