This provides a small fixed pilot flow at center for stability and is common for industrial applications. Actuator Type 7B Single Solenoid with Spring Centered/Return and Mechanical Detent. • Position 1: Solenoid energized (spring return when de-energized). • Position 2: Spring-centered neutral. • Position 3: Mechanical detent (latched position, requires opposite solenoid signal to release). Maximum Operating Pressure 350 bar (5,075 psi) Maximum Flow Rate Approx. 19 L/min (5 US gpm) Dependent on spool and pressure drop. Voltage Not specified in base model Requires a separate solenoid coil (e.g., 24 VDC, 110 VAC) specified by a part number like 6034967-001.
