Mobile control Single Acting

Product description

• Valving Architecture: Mobile control blocks are typically constructed using a modular, "sandwich" sectional design. A single-acting section uses a 3-way, 3-position (or 2-position) spool configuration. The positions are: 1. Raise/Extend: Directs pump flow to the actuator port. 2. Hold/Neutral: Blocks the port, mechanically trapping fluid to lock the load in place. 3. Lower/Retract: Opens the port to the tank line, routing returning fluid back to the reservoir via gravity or spring contraction. • Actuation Types: Designed for heavy-duty mobile environments, these blocks can be actuated manually via mechanical levers, pneumatically, or electronically using 12V/24V DC proportional solenoids integrated into a vehicle's machine bus system (CAN bus) or remote radio joysticks. • Safety Integration: Mobile setups routinely pair single-acting controls with load-holding valves or lowering brakes directly flanged onto the block. This ensures that if a hydraulic line breaks, the single-acting cylinder will not catastrophically collapse under its own weight. • System Efficiency: By eliminating the secondary pressure line required by double-acting cylinders, single-acting configurations save significant space, use fewer hoses, require simpler control logic, and reduce overall machine power consumption during the return cycle.
