Schneider Electric AL-170 Solenoid Air Valve Open Frame 24V

The Schneider Electric (Barber Colman) AL-170 is a 24V, open-frame solenoid air valve designed for applications where an electrical signal controls a pneumatically operated device in HVAC systems. In simpler terms, it's an electronically controlled switch that regulates airflow using compressed air. When energized, the valve opens, allowing compressed air to flow through it and activate pneumatic devices. Conversely, when de-energized, the valve closes, stopping the airflow. The AL-170 is a versatile valve with a corrosion-resistant plastic body, suitable for various NEMA 1 mounting locations. It boasts a compact size (typically 3/8 inches) and can handle pressure up to 680 psi. Additionally, it functions reliably in a wide temperature range, from -40°F to 185°F. This durability makes it ideal for various HVAC equipment, including dampers, actuators, and air handling units. Solenoid valves like the AL-170 offer several benefits for HVAC systems. They provide fast and precise control over airflow, improving efficiency and system responsiveness. Their compact size allows for easy installation in tight spaces, and the corrosion-resistant body ensures long-lasting performance. Furthermore, by using electrical signals to control airflow, solenoid valves simplify system design and operation.
