Aro A249PD pilot air control valve 4-way 2-position 1/8 in port 39 cfm 150 psi

SKU CH-VZRB-F2XCP

A 4-way, 2-position pilot valve with 1/8 in ports, 39 cfm flow and 150 psi rating for remote multi-function control

  • Precise 4-way/2-position control for complex pneumatic circuits
  • 39 cfm flow capacity supports demanding air-tool operation
  • 150 psi rating handles high-pressure shop systems reliably
  • 20 psi pilot pressure enables low-force remote actuation
  • 600 cycles per minute for fast, repeatable machine sequencing

Pilot air control valve for multi-function

The ARO A249PD is a 4-way 2-position pilot-operated valve designed to control multiple machine functions from a single remote location. It suits pneumatic circuits where individual valves manage separate actuators or tools.

Flow limited to 39 cfm at 150 psi maximum pressure

The valve delivers up to 39 cfm with a 150 psi operating ceiling, so high-demand or high-pressure circuits will exceed its capacity. Pilot pressure must reach at least 20 psi for reliable shifting, and cycling tops out at 600 cycles per minute.

Verify port size and temperature range before

The valve uses 1/8 inch ports for both the main and pilot connections, so your plumbing must match NPT 1/8 female threads. Operating temperature spans 0 to 180 °F, and the 3 7/8 inch body length must fit your available mounting space.

Questions about this item

Should I choose this 4-way 2-position pilot valve over other configurations?

This valve provides 4-way 2-position control, meaning it directs airflow between two output ports when the pilot signal is applied, which suits applications needing simple on/off switching of double-acting cylinders.

What does the 39 cfm rating mean when the valve is installed in my system?

The 39 cfm rating indicates the maximum flow capacity at the rated pressure drop, so the valve can pass up to 39 cubic feet per minute of compressed air when pilot pressure is present and supply pressure is adequate.

How does the 1/8 in NPT pilot port affect the pressure I can use?

The pilot port accepts 1/8 in NPT fittings and requires a minimum 20 psi pilot signal to shift the valve, while the main supply pressure can go up to 150 psi through the same port size.
