3/2-way valve with pushbutton, normally closed
Pressing the pushbutton operates the valve. The flow passes freely from 1 to 2. Releasing the pushbutton allows the valve to return to its starting position through the use of a return spring. Connection 1 is shut.
By holding down the Shift key and simultaneously clicking on the component with the mouse cursor, FluidSIM keeps the valve in permanent operating position. Simply clicking on the component cancels the operated state and returns the valve to its starting position.
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.
