WG9000360134 Howo Control Valve

WG9000360134 is a dedicated control valve for SINOTRUK HOWO T7H, T5G, A7, TX and HOWO engineering dumpers. As a key part of the vehicle's hydraulic control system, it adjusts hydraulic oil flow, pressure and direction to match braking, lifting and steering needs. Its optimized valve core ensures sensitive response, stable control, no jamming or oil leakage, even under heavy load, frequent starting/braking and complex roads. It guarantees stable hydraulic system operation, boosts work efficiency and avoids safety risks from control failure.

①Applicable Vehicles: SINOTRUK HOWO T7H/T5G/A7/TX, and HOWO engineering dumpers/mixers with the same hydraulic control system.

②Adaptable System: Matches original hydraulic components (pump, cylinder, oil pipe, sensor) without modifying interface, pipeline or circuit.

③OE Reference Number: WG9000360134

④Interchangeability: Follows original dimensions, interface specs and parameters. Directly replaces original valve, no secondary debugging or bracket/pipeline modification.

⑤Value-added Service: Our team verifies fit via vehicle model, chassis number and hydraulic system type, and provides pre-installation cleaning and post-installation guidance.

Core Materials

Valve body uses quenched-tempered high-strength alloy steel (40Cr) for rigidity, pressure resistance and wear resistance to withstand high-pressure impact. Valve core adopts GCr15 bearing steel for high precision and smooth surface, ensuring sensitive movement and good sealing. Seals are high-temperature oil-resistant fluorine rubber to prevent leakage. Valve seat is 20CrMnTi alloy steel, wear-resistant and non-deformable.

Surface Treatment

Valve body is galvanized and passivated for corrosion and rust resistance in harsh environments. Valve core is precision polished and chrome-plated to reduce friction and ensure flexible movement. Installation surface is precision milled for flatness and tight fit with the bracket.

Production Craftsmanship

Adopts CNC precision machining + heat treatment + precision assembly. Valve body and core are CNC-machined for accurate dimensions and good matching. Core-body clearance is strictly controlled at 0.002-0.004mm for sealing and sensitivity. Each valve passes pressure, leakage and action tests before delivery.

• Quality Grade: OE-matching, meets HOWO standards and national hydraulic component requirements. Passed 1,000-hour high-pressure durability test, consistent with original parts.
• Inspection Items: High-pressure leakage (25MPa), flow accuracy, pressure regulation, core sensitivity, dimensional accuracy and surface treatment.
• Quality System: Factory passed IATF16949 and ISO9001, full-process control from raw materials to delivery.
• Batch Tracking: Each valve has laser-engraved OE, batch number and production date. Records kept ≥3 years for full traceability.

• Average Service Life: ≥3 years (300,000km), matching HOWO maintenance cycle, reducing replacement and costs.
• Performance Advantages: High-pressure resistance, no leakage; sensitive core action; wear-resistant, long service life; good sealing for frequent use.

• Harsh Environment Adaptability: Stable at -40℃~120℃, fits alpine, high-temperature, humid and dusty conditions. Strong vibration resistance for heavy-load jolts.

Common Fault Optimization

Aims at original faults: oil leakage, core jamming, unstable pressure, inaccurate flow and short service life. Optimized materials, structure and surface treatment solve these issues, avoiding hydraulic failure and safety hazards, reducing maintenance.

Maintenance & Replacement Value

Simple structure, easy to disassemble and assemble on-site with common tools, cutting maintenance time by 45%. Fully compatible, no extra debugging, ready to use. Stable performance reduces downtime and operating costs.

Packaging Configuration

Three-layer shockproof packaging: inner EVA foam, middle plastic cover, outer reinforced carton. Valve is fixed with positioning bracket to avoid collision. Oil ports are sealed with plastic plugs. Matching accessories (bolts, gaskets) are independently packaged.

Marking Specifications

Outer Carton: Printed with OE, product name, vehicle model, quantity, batch number, weight, and moisture-proof/shock-proof/fragile signs. Export has multilingual instructions.

Product Marking: Laser-engraved OE, rated pressure and batch number on valve body, wear-resistant and clear.

Customization Service: Neutral packaging and LOGO customization available. Carton printing, language and size adjustable by market needs.
