ASCO 99-257-1D Solenoid Coil

ASCO 99-257-1D is a replacement solenoid coil for ASCO Red Hat valve assemblies, offered as a dual‑voltage unit that operates on 120 VAC at 60 Hz or 110 VAC at 50 Hz to match regional power standards. The coil draws 15.4 watts and is cataloged as both 99-257-1-D and 099257-001-D, serving as a direct replacement for worn or failed coils in compatible 2/2 normally closed valves, including configurations used with 1-inch valve bodies. Built as a molded, long‑life coil, it features extended ends to simplify installation and a PTFE exterior seal for reliable external sealing in typical industrial environments. This replacement coil is designed for actuation of ASCO solenoid valves and is widely stocked by distributors to support maintenance of ASCO valve systems that rely on Red Hat coil technology. When selecting a replacement, verify the correct voltage reference for your installation (120/60 or 110/50 service) and ensure compatibility with your ASCO valve model and size, since the 99-257‑1D family encompasses variants aligned with different regional power standards and valve configurations.
