Aro/ingersoll-rand A312PD 4-way Solenoid Air Valve 150 Psi

Product Description

The ARO/INGERSOLL-RAND A312PD is a 4-way, 3-position, body-ported solenoid air valve designed for pneumatic control applications in industrial and mechanical systems. It features a pilot actuator with pilot return operation and handles a maximum working pressure of 150 psi. Port size is 1/4 inch inlet by 1/4 inch outlet. With a flow coefficient (Cv) of 1.5 and a rated flow of 54 CFM, this valve delivers reliable directional control for actuators, cylinders, and other pneumatic devices. Licensed HVAC and mechanical technicians, as well as industrial pneumatic specialists, typically install and service this component.

The A312PD suits applications where a pilot-operated, 3-position directional control valve is needed in a compact form factor. Its body-ported design keeps external plumbing to a minimum. The valve operates across a temperature range of 0 to 180 degrees F, making it appropriate for a range of industrial and light commercial pneumatic control systems where a 4-way valve configuration is required to manage bidirectional actuator movement or cylinder sequencing.

Key Features

• 4-way, 3-position directional control for bidirectional pneumatic actuator applications
• Pilot actuator with pilot return operation for reliable switching
• Maximum working pressure of 150 psi (10.2 bar)
• Flow coefficient (Cv) of 1.5 with 54 CFM rated flow
• Body-ported design minimizes external manifold plumbing
• 1/4 inch inlet and 1/4 inch outlet ports in a compact body envelope
• Operating temperature range of 0 to 180 degrees F

Compatibility

Designed as an OEM-style directional control solenoid valve for 1/4 inch ported pneumatic systems requiring 4-way, 3-position pilot-operated valve function at up to 150 psi working pressure.

Installation Notes

Installation should be performed by a qualified pneumatic or mechanical technician familiar with directional control valves and compressed-air system safety. Depressurize the pneumatic circuit fully before removing or installing the valve. Verify that supply pressure does not exceed the 150 psi maximum rating during commissioning. Follow applicable local mechanical codes and the manufacturer's wiring guidelines when connecting the solenoid coil to the control circuit.
