"This industrial hydraulic directional control valve conforms to the National Fluid Power Association NFPA D03 mounting pattern for subplate or manifold mounting. As a four-way valve, it is commonly used to extend and retract a double-acting hydraulic cylinder or to control a rotary hydraulic motor. As a spring-centered valve, it will remain in its home position with all-ports commonly connected until shifted electrically to one of two positions to either extend or retract a cylinder, returning to home when the power is removed. Its molded coils are moisture and dirt resistant. Indicating signal lights, manual override, bolt kit and electrical junction box are standard. The valve mounts on Northern Tool Subplate 203221 with 1/4in. NPT ports or 203231 with 3/8in. NPT ports. Indicator Light Yes, Volts 12 DC, Max. PSI 4,500, Directional Control 4-way, 3-position, GPM 16.8.
