ASCO EF8551A1MS Pneumatic Solenoid Control Valve

ASCO EF8551A1MS Pneumatic Solenoid Control Valve is a direct-mount inline spool valve from the Series 8551 family that governs compressed air in compact automation circuits; it operates over a pressure range of 3 to 150 psi and uses 1/4-inch NPT ports for space-efficient installation. The EF8551A1MS variant is a single-solenoid valve with a 24 VDC coil, while other coil configurations are offered under EF8551A001MS (120/60 VAC) and EF8551A002MS; coil power is typically around 6.3 watts, with variants reflecting different voltages and coil insulations. Designed for direct mounting to pneumatic actuators, this valve provides reliable directional control of cylinders and other pneumatic devices in industrial automation and HVACR applications, leveraging a compact inline footprint and the Series 8551’s direct-mount compatibility. With a nominal 1/4-inch port size and robust construction, EF8551A1MS supports precise actuation in control circuits where quick response and space efficiency matter, making it suitable for integrated control in automated lines, packaging equipment, and process-control systems.
