Doosan DH35 Main Control Valve Assembly – 100% Brand New (OEM 2436-1002 / 2436-1002A)

The hydraulic command network on the 3.5-ton Doosan DH35 and Daewoo Solar 035 mini excavator directs high-pressure fluid to the boom, arm, bucket, boom swing offset, front dozer blade, and travel circuits. Tatan Machinery supplies 100% Brand New multi-spool hydraulic main control valve assemblies (OEM part numbers: 2436-1002 / 2436-1002A, interchangeable with 2436-1002B / 401-00057). Manufactured to strict OEM micrometer tolerances with micro-lapped spools and factory-set relief cartridges, each complete unit restores rapid cycle times and holding power. Backed by our 12-Month Comprehensive Replacement Warranty.

Step 1: Confirm Valve Identification & Wholesaler Standard

Tatan Machinery is a verified first-party physical stocking wholesaler of excavator components. All our hydraulic valves, pumps, and travel drives are 100% Brand New (our diesel engine assemblies are remanufactured to OEM tolerances).

Step 2: Verify Machine Fitment & Hydraulic Circuit Matching

The 2436-1002 valve series serves several Doosan/Daewoo 3-ton to 4-ton mini excavator series. Please review your machine model:

Step 3: Inspect Actual Product Build & Spool Design

This control valve is 100% Brand New with zero operating hours. We do NOT supply worn salvage cores. Key mechanical features include:

• Micro-Finished Alloy Steel Spools: Precision ground and matched to individual cast bores to guarantee minimal internal oil bypass and zero cylinder creep.
• Integrated Safety Check Valves: Pre-fitted with factory-set main relief cartridges, port overload relief valves, and pilot-operated holding valves on the boom and dozer circuits.
• Heavy-Tensile Cast Monoblock: Dense cast iron architecture designed to withstand continuous 24.5 MPa working pressure surges without body cracking.

Step 4: Watch Live Warehouse Inventory & Physical Stock Video

Because this is a 100% Brand New hydraulic component (only our diesel engine assemblies are remanufactured), we document our physical warehouse stockholding, palletized inventory, and port-sealing quality directly on camera:

Step 5: Review 12-Month Quality Warranty Protection

Every 100% Brand New 2436-1002 control valve supplied by Tatan Machinery comes backed by our 12-Month Comprehensive Replacement Guarantee:

• Full Hydraulic Integrity Coverage: Casting crack failures, internal spool scoring, dozer holding valve leakage, and relief regulation failure resulting from manufacturing defects.
• Direct Replacement Support: If any defect occurs under proper hydraulic maintenance, we dispatch immediate replacement components or assemblies without lengthy disputes.

Step 6: Heavy Export Packaging Protocol

A heavy 45 kg valve block requires clinical protection against contamination and transit shock:

• 100% Sealed Port Caps: Every hydraulic work port, pump inlet, tank return, and auxiliary line port is sealed with heavy-duty threaded protective plugs.
• VCI Vapor-Phase Anti-Corrosion Wrap: The bare valve block is coated with rust-inhibiting hydraulic film and hermetically vacuum-sealed in VCI plastic foil.
• Custom Internal Structural Timber Cushioning: Bolted securely onto structural base timbers inside the crate to prevent any shift.
• ISPM 15 Fumigation-Free Solid Plywood Box: Fully enclosed export crate banded with multiple high-tensile galvanized steel straps.

Actual sealed port caps, protective anti-corrosion wax, and reinforced wooden crating

Step 7: Supported Global Logistics & Customs Documentation
