3/2-way idle return roller valve, normally closed
The idle return roller valve is operated when the roller is driven in a specific direction by the switching cam of a cylinder. After releasing the roller, the valve returns to its initial position through the use of a return spring. Connection 1 is shut. When the roller is driven in the opposite direction, the valve is not operated.
In the Simulation Mode, the valve can be switched manually by clicking on the component, thus not requiring a cylinder to operate the valve.
This valve is derived from a configurable 3/n way valve. You find this valve in the component library Frequently used Way Valves
, under the menu.
