Industrial JJ400 Valve

Industrial JJ400 Valve is an ATKOMATIC solenoid valve in the JJ Series, designed for clean-media control in general automation lines. It uses 1/2 in NPT inlet/outlet ports and is powered by a 115 VAC coil (60 Hz), making it compatible with common control circuits. The valve is specified for a pressure range from 5 to 250 psi, suitable for mid‑range applications, and its main seat/orifice arrangement yields a Cv of 3.5 for predictable flow in compact installations. As part of the JJ family, the JJ400 shares the design approach of easy coil replacement without removing the valve from the line and supports standard 1/2 in connections, which aids retrofit into existing piping. This model is referenced in Atkomatic’s literature and catalog listings, including 1/2 in port configurations and 115 VAC coil variants.
