Differential Pilot Valves
Differential Pilot models are operated with a button bleeder that shifts the spool. The loss of pressure through the button bleeder shifts the internal spool.
|2-position, double differential pilot, friction positioned. Spool stays in shifted position when buttons are released.|
|2-position, single differential pilot, spring returned spool. Spool returns to position "C" when the button is pressed.|
|3-position, spring centered. Spool returns to center position when both buttons are closed or open.|
