Aro/ingersoll-rand A312SD-024-D Solenoid Air Valve 24VDC 4-way

Product Description

The ARO/INGERSOLL-RAND A312SD-024-D is a 4-way, 3-position, body ported solenoid air valve designed for directional control of compressed air in pneumatic systems. It operates on 24 VDC input and delivers a flow rate of 32 CFM with a Cv of 0.9. The valve uses a solenoid actuator with solenoid return, providing reliable spring-centered or detented positioning depending on the circuit configuration. Port connections are 1/4 inch inlet and 1/4 inch outlet. This valve is installed by industrial maintenance technicians, pneumatic systems integrators, and automation specialists working on equipment that requires precise air direction control.

This valve is suited for use in industrial pneumatic circuits, automated machinery, and process control equipment where 4-way directional control is required. Its body ported design keeps external plumbing minimal and supports compact panel or manifold mounting. At 150 psi maximum working pressure, it handles typical plant air supply systems without issue. The 3-position configuration allows for center-condition flow management, making it applicable in systems that require a defined mid-stroke state such as exhaust center or pressure center circuits.

Key Features

• 4-way, 3-position solenoid-actuated directional control valve
• 24 VDC solenoid input with solenoid return actuation
• 32 CFM flow rate with a Cv of 0.9 for moderate flow applications
• 150 psi maximum working pressure rated for standard plant air
• Body ported design reduces external fittings and plumbing complexity
• 1/4 inch inlet and 1/4 inch outlet ports for straightforward line connections
• Compact footprint: 2-15/16 inches long x 1-15/16 inches wide x 1-13/16 inches high

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial pneumatic directional control valve applications requiring a 4-way, 3-position, body ported configuration with 1/4 inch porting and 24 VDC solenoid operation.

Installation Notes

Installation should be performed by a qualified pneumatic systems technician or industrial maintenance professional. Depressurize the air supply and de-energize all electrical circuits before removing or installing the valve. Verify supply voltage matches the 24 VDC solenoid rating before applying power. Follow applicable pneumatic system codes and manufacturer wiring guidelines when connecting the solenoid leads.
