Product Overview

  Hydrocontrol HC-D6/5-IL009(175)AG05 W001AH001F001A-TK G05 is a 5 Spool Hydraulic Valve and Mobile Hydraulic Valve with 35 MPa rated pressure and 100 L/min rated flow.Designed for manual or pilot hydraulic control,it serves marine systems,rock drills,rescue vehicles,and mobile hydraulic equipment.

  Product Type Definition

  A multi-spool hydraulic directional control valve is a device that directs fluid flow to multiple actuators from a single valve assembly.This category includes sectional and monoblock configurations distinguished by spool count,spool type(open center,closed center,tandem center),and actuation method.The HC-D6/5 falls into the high-pressure multi-spool mobile valve segment,combining 5 independently operable spools with compact dimensions for space-constrained installations.For applications requiring simultaneous control of multiple hydraulic functions,a multi-spool valve eliminates the need for separate valves,reducing potential leak points and simplifying system plumbing.

  Technical Highlights

  Five independent spools in a compact monoblock body:The 5-spool configuration provides simultaneous control of up to 5 hydraulic actuators,reducing installation footprint and eliminating multiple separate valves.This consolidation reduces potential leak points by up to 60%compared to single-spool valve assemblies.

  Manual and pilot hydraulic dual-mode operation:The valve accepts either direct manual lever input or external pilot hydraulic signals for remote control applications,offering deployment flexibility across both operator-present and automated machinery configurations.

  Standardized G3/4 inch threaded ports across all work ports:Uniform port sizing across P,A,B,and T ports simplifies hose kit design,reduces inventory requirements,and minimizes installation errors common with mixed port configurations.

  35 MPa high-pressure rating suitable for heavy-duty mobile hydraulics:At 35 MPa,the valve operates within the typical pressure range for demanding applications such as hydraulic rock drills and rescue vehicle outriggers,where sustained high pressure is required for break force and holding torque.The design supports proof testing to 52.5 MPa as specified in ISO 10770-1 standards for structural integrity validation.

  100 L/min flow capacity for multi-function simultaneous operation:The rated flow supports concurrent operation of multiple functions without pressure drop degradation,ensuring that a boom lift function does not starve a rotating or tilting function under simultaneous demand.

  Applications

  Marine hydraulic systems:Delivers 5–10%measurable energy savings through optimized valve design that minimizes internal leakage and reduces auxiliary engine load,directly improving vessel CII(Carbon Intensity Indicator)ratings.

  Hydraulic rock drills:Provides precise directional control for percussion,rotation,and feed functions simultaneously,enabling faster cycle times and reduced bit wear through consistent flow distribution.

  Road rescue vehicles:Powers outrigger deployment,boom extension,and winch operations from a single control interface,reducing vehicle setup time by eliminating valve switching.

  Mobile hydraulic equipment:Handles loader arm lift,bucket tilt,auxiliary attachment flow,steering,and braking functions in compact machinery such as skid steers and telehandlers,where panel space is at a premium.

  Agricultural machinery:Controls implement lift,folding wings,PTO engagement,and steering assist functions,with the 5-spool configuration matching typical tractor valve section requirements.

  Selection Guidance

  Suitable for:Systems requiring simultaneous control of 3–5 hydraulic functions from a single operator station,such as loader backhoes,excavator attachment circuits,and marine deck machinery consoles.

  Suitable for:Applications with mixed manual and automated control needs,where some functions require direct operator lever control and others accept pilot hydraulic signals from remote joysticks or automation controllers.

  Suitable for:Mobile equipment operating at 25–35 MPa with flows up to 100 L/min,including medium-duty construction machinery,forestry equipment,and material handling vehicles.

  Suitable for:Retrofit and replacement scenarios where existing single-spool valves are being consolidated to reduce plumbing complexity and leak points.For applications requiring low-temperature operation down to-20°C,the valve maintains consistent performance with appropriate fluid selection(e.g.,synthetic or high-VI mineral oils).

  Not recommended for:Systems requiring proportional or servo control beyond basic directional switching.For proportional flow control requirements,consider a proportional valve with integrated electronics per ISO 10770-1.

  Not recommended for:Applications with sustained flows exceeding 120 L/min or pressures above 38 MPa,where larger port sizes(e.g.,G1 inch or SAE 12)are required for acceptable pressure drop and service life.

  Not recommended for:Electro-hydraulic systems that require solenoid actuation.This valve offers manual and pilot hydraulic control only;solenoid-operated alternatives are available for fully electric control interfaces.

  FAQ

  1.What hydraulic fluids are compatible with the HC-D6/5 valve?

  Mineral oil-based hydraulic fluids meeting ISO VG 32,46,or 68 specifications are compatible.The valve is also compatible with phosphate esters and water-glycol mixtures,but seal material compatibility should be verified for specific fluid types.For water-glycol mixtures,confirm that internal components are specified for the lower lubricity of these fluids.

  2.What is the maximum operating pressure and flow for continuous duty?

  35 MPa and 100 L/min are the rated continuous duty limits.Intermittent operation up to 38 MPa is permissible for peak loads not exceeding 10%of total operating time,per manufacturer design guidelines.Exceeding 38 MPa may reduce spool-to-bore clearance tolerances and accelerate wear.

  3.What is the operating temperature range and IP rating?

  -20°C to+80°C with appropriate fluid selection,and IP65 ingress protection per IEC 60529 when all ports are properly capped or connected.IP65 means the valve is dust-tight and protected against low-pressure water jets from any direction,making it suitable for outdoor mobile equipment and marine deck installations exposed to rain and washdown.

  4.How is the valve installed and maintained?

  The valve mounts directly to hydraulic lines via G3/4 threaded ports.No special mounting bracket is required for panel or console mounting.Internal leakage should be checked every 2000 operating hours by measuring cylinder drift;spool replacement is typically required after 10,000–15,000 hours under rated conditions.

  5.How does the 5-spool HC-D6/5 compare to using five single-spool valves?

  The 5-spool valve reduces potential leak points by approximately 60%(from 20 port connections to 8),lowers installation labor by eliminating individual valve mounting and inter-valve plumbing,and reduces overall footprint by up to 50%.For applications where individual valve replacement or function isolation is required,separate single-spool valves may be preferable despite higher leak risk.
