Foot-Operated Valve Fit for DX260 Excavator

1. Product Overview

• Name: Foot-Operated Hydraulic Control Valve

• Compatibility: Specifically designed forDoosan DX260 excavators(or similar mid-to-large hydraulic machinery).

• Function: Enables hands-free hydraulic control (e.g., activating attachments like breakers, tiltrotators, or grapples) via a foot pedal, improving operator efficiency and safety.

2. Key Technical Specifications

【表格】

Parameter Details

Operating Pressure Up to 35 MPa (5,075 PSI) – Matches DX260’s standard hydraulic system.

Flow Rate Adjustable (typically 60–180 L/min) to suit various attachments.

Valve Type Pilot-operated or direct-acting (depending on model).

Port Sizes Standard SAE/DIN ports (e.g., #12 SAE for high-flow applications).

Material Hardened steel valve body, corrosion-resistant coating.

Mounting Floor-mounted or side-mounted bracket (customizable for cab layout).

3. Advantages for DX260 Operators

• Ergonomic Efficiency:

• Frees hands for primary controls (e.g., boom/bucket operation) while using feet for secondary functions.

• Reduces operator fatigue during repetitive tasks (e.g., breaking rocks).

• Safety:

• Minimizes distractions by avoiding hand-switching between levers and pedals.

• Critical for tasks requiring simultaneous movement (e.g., stabilizing while breaking).

• Flexibility:

• Compatible with DX260’s auxiliary hydraulic circuits (e.g., 1st/2nd auxiliary lines).

• Supports quick-change couplings for rapid attachment swaps.

4. Installation Considerations

• OEM vs. Aftermarket:

• OEM (Doosan Original): Guaranteed compatibility but higher cost.

• Aftermarket: Cost-effective alternatives (e.g., Eaton, HydraForce, or Sun Hydraulics), but verify specs match DX260’s system.

• Professional Installation:

• Requires hydraulic system knowledge to avoid pressure mismatches or leaks.

• May involve rerouting hoses or adding pressure relief valves.

5. Maintenance Tips

• Daily Checks:

• Inspect for hydraulic fluid leaks around the valve body or pedal linkage.

• Ensure pedal movement is smooth (no sticking or excessive play).

• Monthly Maintenance:

• Clean debris from the valve area to prevent contaminants from entering the hydraulic system.

• Check hose fittings for tightness.

• Annual Overhaul:

• Replace seals/O-rings if wear is visible.

• Test valve response time and adjust if sluggish.

6. Common Issues & Fixes

Issue Probable Cause Solution

Valve not responding Air in hydraulic lines or low pressure. Bleed air, check pump output.

Leaking fluid Worn seals or damaged fittings. Replace seals; tighten/replace fittings.

Stiff pedal Contaminated hydraulic oil or corroded parts. Flush system; lubricate moving parts.
