Item # R431003743, Rexroth 3-Way Normally Closed Pilotair® Cartridge Valves


"A" Pilotair® Pneumatic Directional Control Valves
Three Way-Normally Closed Cartridge Valves

OPERATION

The "A" PILOTAIR® cartridge valve is a mechanically operated (straight push) 3-way directional control valve. It can be easily used in manifolds or in custom installations. This cartridge valve can also be used to graduate pressure (consult factory for additional information).

In release position, as shown, the valve disc seals on the inlet valve seat and closes the passage from the inlet to the outlet. The outlet is vented to atmosphere through the center of the plunger. As the plunger is forced downward by an external force, it seats on the valve disc. This seals the passage between the outlet and exhaust.

Further downward travel of the plunger unseats the valve disc from the inlet valve seat and allows inlet air pressure to flow to the outlet.

Release of the external force, allows the plunger and valve to spring return to the original position.

Install the valve to ensure operation within the travel limits shown on the outline drawings. Travel beyond these limits can cause damage to the valve.
