ZOOMLION RK504-Tractor HydraulicMultiwayValve
₦26,500,000.00
Key Features
1. OEM Precision & Direct Fitment
-
Factory Match: Precision-engineered to exact original equipment manufacturer (OEM) specs for the Zoomlion RK504 (50HP) tractor platform.
-
Direct Bolt-On Replacement: Features standard mounting points and metric/BSP hydraulic thread connections for seamless installation without system modifications.
2. Heavy-Duty Pressure & Flow Handling
-
High-Pressure Rating: Rated for operational pressures up to 20 MPa (200 bar), maintaining steady hydraulic force under heavy farm loads.
-
Optimized Flow Rate: Manages fluid delivery rates of 40–60 L/min, enabling fast, smooth operation of 3-point hitches, loaders, and implements.
3. Built-In System Safety & Protection
-
Integrated Main Relief Valve: Protects the hydraulic pump and lines from over-pressurization and thermal expansion spikes during heavy lifting.
-
Internal Check Valve: Prevents hydraulic fluid backflow, holding raised implements steadily in position without slippage or sudden drops.
4. Durable Industrial Construction
-
High-Tensile Cast Iron Body: Resists cracking, internal wear, and structural fatigue under high mechanical stress.
-
Precision Hard-Chrome Spools: Hardened inner spools resist scoring and fluid bypassing, reducing internal pressure loss.
-
High-Temperature Oil Seals: Fitted with leak-proof NBR/O-ring seal kits that withstand high hydraulic oil temperatures during extended field operations.
5. Versatile Multi-Spool Control
-
Flexible Actuation: Features spring-center return and detent positions for both immediate response and sustained fluid flow to hydraulic motors or dumping trailers.
-
Multi-Implement Compatibility: Provides complete directional control for rear 3-point linkages, front-end loaders, hydraulic trailers, and trailing implements.
Product Overview
The Hydraulic Multi-Way Directional Control Valve (also known as the hydraulic distribution block or spool valve assembly) is a key fluid-power control unit engineered specifically for the Zoomlion RK504 50HP 4WD Tractor. It regulates hydraulic fluid flow, pressure, and direction from the main hydraulic pump to power the tractor’s 3-point linkage lift system, auxiliary remote valves, and front/rear hydraulic attachments (such as loaders, tippers, and plows).
Key Technical Specifications
-
Compatibility: Zoomlion RK504 / RK Series 50HP Tractors (also compatible with select RK and Chery/Detank 40–50HP platforms).
-
Valve Type: Sectional / Monoblock Multi-Way Directional Control Valve.
-
Control Mechanism: Mechanical Hand Lever or Cable-Actuated Spools (typically 1-spool, 2-spool, or 3-spool configurations depending on remote outlet options).
-
Body Construction: High-tensile, anti-corrosive cast iron body with hardened chrome-plated steel inner spools for high-pressure durability.
Key Features & Built-In Safety
-
Integrated Main Relief Valve: Built-in safety pressure relief valve protects the tractor’s hydraulic pump, lines, and cylinders from over-pressurization during heavy lifting.
-
Check Valve Assembly: Prevents backflow of hydraulic oil, ensuring that raised implements (such as heavy plows or trailers) do not slip or fall when shifting levers.
-
Detent / Spring Return: Features automatic spring-center return or detent locking positions for continuous hydraulic flow (ideal for hydraulic motors or sustained dumping).
-
Precision Spool Machining: High-precision internal tolerances eliminate internal fluid bypassing, delivering precise response and smooth lifting/lowering speeds.
Primary Applications & Functions
-
Three-Point Hitch Control: Regulates the raising, holding, and lowering speed of rear-mounted implements (harrows, seeders, slashers).
-
Auxiliary Remote Outlets: Supplies hydraulic power to external dual-acting or single-acting hydraulic cylinders (e.g., hydraulic tipping trailers, front-end loaders, or log splitters).
Maintenance & Replacement Guidelines
-
Symptoms of Failure: Slow/jerky implement lifting, inability to hold raised loads, fluid leaking from spool shafts, or pressure drops across the hydraulic system.
-
Installation Advice: Flush the hydraulic oil system and replace hydraulic filters prior to installing a new multi-way valve to prevent metal shavings or debris from scoring the precision inner spools.
