Schneider Electric (Barber Colman) AL-151 Valve

The Schneider Electric (Barber Colman) AL-151 is a high-performance 120Vac solenoid air valve designed for precision control in pneumatic temperature control systems. This commercial-grade solenoid air valve features a durable brass body for extended service life and reliable actuation in demanding HVACR environments. Engineered with a 1/8" NPT connection, it provides a consistent airflow of 1.15 scfm, making it ideal for directing supply air to pneumatic actuators and dampers based on electrical circuit signals. The AL-151 is functionally identical to the AL-151-0-0-1, ensuring a direct drop-in replacement for legacy Barber Colman systems. Its robust construction is rated for operation in environments with 50 to 95% relative humidity. For streamlined field installation, each unit includes a dedicated mounting bracket, allowing for secure positioning within control cabinets or on-equipment frames. This three-way valve is essential for technicians managing pneumatic control valves and automation sequences that require 120V coil switching.

• Durable Brass Construction: The heavy-duty brass body ensures long-term resistance to corrosion and mechanical wear in HVACR applications.
• Universal Compatibility: Fully interchangeable with AL-151-0-0-1 part numbers for seamless system integration.
• High Humidity Rating: Operates reliably in moisture-heavy environments (up to 95% RH) without compromising solenoid performance.
• Complete Installation Kit: Includes a mounting bracket to simplify retrofit or new-build mounting on standard surfaces.
• Efficient Airflow: Delivers a steady 1.15 scfm, optimized for standard pneumatic control loops and pilot-operated devices.

• Is the Schneider AL-151 compatible with older Barber Colman systems? Yes, this unit is the standard replacement for legacy Barber Colman solenoid valves and is specifically cross-referenced with the AL-151-0-0-1.
• Does this valve support both energized and de-energized air direction? Yes, as a 3-way pneumatic solenoid, it is used to direct supply air to a device when the coil is energized or to exhaust it when de-energized.
• What is the thread size for the air ports? This valve utilizes standard 1/8" NPT threaded connections for easy fitting with high-pressure pneumatic tubing.
