Schneider Electric (Barber Colman) AL-171 Air Valve

The Schneider Electric (Barber Colman) AL-171 Solenoid Air Valve is a reliable 120 Vac industrial component engineered for precise pneumatic signal control in HVACR and fluid power systems. Featuring an durable plastic open frame design, this 0.3 scfm valve is built for vertical mounting in NEMA 1 environments, handling operating pressures up to 30 psi. As a primary HVAC solenoid air valve replacement, the AL-171 provides seamless continuity for legacy systems, acting as a direct drop-in for discontinued models including 2368-452 and VEC-1012. Its integrated 18-inch electrical leads simplify field wiring for contractors managing pneumatic-to-electric transitions. Designed for air and inert gas media, this 120V solenoid air valve ensures consistent performance across an ambient temperature range of 40°F to 130°F. Techs can rely on its 5.7W power efficiency and cRUus and CSA standards compliance for robust industrial applications.

• Direct Legacy Compatibility: Engineered as the exact replacement for the 2368-452 and VEC-1012, eliminating the need for manifold modifications.
• Precision Airflow Control: Rated at 0.3 scfm and capable of managing a 30 psi maximum differential, ideal for sensitive pneumatic logic.
• Simplified Installation: Includes pre-installed 18-inch electrical leads and an open frame coil design for easy access in tight control cabinets.
• Industrial-Grade Materials: Constructed with high-strength plastic and rated for IP10 protection, ensuring longevity in standard commercial environments.

Common Technical Questions

What are the primary replacement cross-references for this valve?
The AL-171 is the direct technical replacement for the Barber Colman 2368-452 and the VEC-1012 solenoid valves.

Does this valve support media other than compressed air?
This unit is specifically rated for air and inert gases. For fluid or fuel applications, verify compatibility with the plastic body material and operating pressure limits.

What is the proper mounting orientation for the AL-171?
For optimal performance and to prevent internal debris accumulation, this solenoid valve should be mounted in a vertical orientation.
