ASCO EF8551A001MS Solenoid Valve Coil 120 VAC

ASCO EF8551A001MS is a four‑way inline spool solenoid valve with an integrated 120 VAC coil, designed for explosion‑proof and watertight operation in hazardous environments. It uses 1/4" NPT ports on an aluminum body, with NBR sealing and a pressure range of 30 to 150 psi, plus fluid temperatures up to 104°F, making it suitable for compressed air and other compatible fluids. The coil consumes about 6.3 watts at 120 VAC (60 Hz) and ships with 18 inches of lead length for easy wiring; configurations for explosion‑proof coils and multiple enclosure approvals (UL Listed, CSA Certified, CE Marked) are standard, including NEMA 3/3S and 4/4X/6/5P/7/9 ratings. An exhaust port is provided via 1/8" NPT, and some editions support a 1/2" conduit connection for remote mounting. The EF8551A001MS is a convertible valve design, allowing transitions between 3/2 and 5/2 configurations, which broadens its applications in automated pneumatic systems. Typical uses include control of air or inert fluids in automation equipment and hazardous‑area installations where a compact, reliable 4‑way valve with a 120 VAC actuation is required; for service or replacement, compatible coil assemblies and replacement coil codes (e.g., 266762‑902‑D) are documented by the manufacturer.
