3/2-way valve, pneumatically operated, normally open
The pneumatic valve is controlled by applying a pilot pressure at connection 10. Connection 1 is shut. By stopping the signal the valve is set back to its starting position through the use of a return spring. The flow passes freely from 1 to 2.
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.
