Bulldozer Pilot Control Valve

Body part number: 702-16-02290 This bulldozer pilot control valve fits bulldozer models including D65-12, D65PX, D85-18, D85EX and other full-range machines with matching hydraulic systems. It can directly replace the original pilot control handle assembly of identical specifications, requiring no extra modification or adjustment of existing oil pipelines.

Product Features

ntegrated all-in-one design: This bulldozer pilot control valve comes fully assembled with drive motor, valve body, operating handle and wiring harness before delivery. Users can mount it straight out of the box without assembling scattered spare parts, greatly cutting down maintenance downtime.

Wear-resistant & leak-proof valve body: The aluminum alloy valve body matches a precisely ground steel valve core. Oil-resistant, anti-aging rubber sealing rings effectively stop internal and external hydraulic oil leakage even after long hours of continuous operation.

Reliable electronic control signals: Equipped with OEM-style multi-core color wiring harness and waterproof plug, it maintains stable signal transmission under bumpy roads and low-temperature environments, free of slow response or functional failure.

Heavy-duty dustproof structure: A thickened corrugated nitrile rubber boot at the handle bottom blocks construction mud and grit from invading the valve core, minimizing sticking and blockage faults to extend the component's service lifespan.

Light & smooth operation: Adopting pilot hydraulic driving instead of outdated mechanical pull rods, it delivers soft, low-resistance manipulation to ease operator fatigue during all-day work shifts.

OEM 1:1 mold replication: Flange mounting holes, threaded operating shaft, hydraulic ports and electrical connectors are all manufactured to match original dimensions perfectly, with zero fitting tolerance during replacement.

Wide adaptability to harsh environments: All metal components feature anti-rust coating, while rubber accessories withstand extreme high and low temperatures. The bulldozer pilot control valve performs steadily in dusty, humid job sites such as mines, road construction and land grading projects.

Main Applications

Equipment matching: Official replacement spare part for all Komatsu D65 and D85 series tracked bulldozers;

Working scenarios: Mining overburden removal, highway infrastructure, site leveling, muck haulage and water conservancy engineering;

Target buyers: Construction machinery repair shops, bulldozer rental fleets, large construction contractors and aftermarket parts distributors;

Replacement occasions: Used when original control lever suffers oil seepage, valve core jamming, electronic signal breakdown, handle breakage or aged dust boot damage.
