Description
The ASCO SC8551A17MS Spool Valve 1/4″ is a solenoid-operated directional control valve designed to regulate air or fluid flow within pneumatic and control circuits. It features a 5-port, 2-position configuration that directs flow paths based on electrical actuation, supporting precise switching between operating states. The 1/4-inch connection size allows integration into compact control lines, while the 120V coil enables electrical activation in standard control setups. It is commonly applied in industrial control panels, actuators, and automation assemblies. In HVAC systems, it manages airflow or pneumatic control signals, supporting coordinated operation of dampers, actuators, and other system components.
