Alco Controls XA1550-103 Solenoid Coil Type S

The XA1550-103 Solenoid Coil is a coil-only replacement for Alco Controls Type S valve assemblies, designed to energize the solenoid with 115V AC at 60 Hz so the valve can switch reliably in automated process-control systems. This model, identified as XA1550-103 and carrying the Type S designation, specifies 115V and 60 cycles, matching common North American electrical standards for industrial solenoids and ensuring compatibility with existing wiring and control circuits in compatible Alco Controls valves. In practical use, the coil is installed to actuate the valve plunger when energized, enabling precise control of liquids or gases in applications such as water treatment, chemical processing, and other industrial process lines that rely on Alco Controls’ solenoid valve technology. When selecting a replacement, verify that the target valve body accepts the XA1550 series Type S coil and that the voltage and frequency requirements align with your control system to maintain proper valve performance and electrical safety.
