ASCO EFHTL8551G417MS Solenoid Valve

ASCO EFHTL8551G417MS is a 1/4-inch, four-way spool solenoid valve from ASCO’s low-power 8551 family, designed for precise control of compressed air and similar gases at 30 to 150 psi. The MS suffix indicates a manual operator option, providing a push-and-turn manual override integrated into each solenoid endcap (MS adds 0.468 inches to each endcap). This model is documented with 120 VAC, 60 Hz (and variants such as 110 VAC, 50 Hz in catalog listings) coil voltages, aligning with common North American and international power standards. The valve features 1/4-inch ports and a four-way spool configuration, enabling actuation of pneumatic circuits in compact form. As part of ASCO’s low-power line, this series is designed for energy-efficient operation, with the 8551 family typically referenced as 1.4 W low-power solenoid valves.
