Our heavy-duty lifting valve is engineered to excel under extreme conditions with a 25MPa pressure rating and 150L/min flow capacity. This high-power design is crucial for tipper truck hydraulic systems in mining and construction, where fast cycle times and the ability to handle massive loads directly impact profitability. The robust construction ensures your vehicle can manage heavy payloads efficiently, reducing overall dump cycle times and increasing transport productivity. This makes it the perfect hydraulic control valve for dump trucks that cannot afford downtime or sluggish performance.
A key innovation of this proportional control lifting valve is its ability to provide smooth, controlled descent of the dump body. By regulating the air signal to the pneumatic pilot, operators can achieve precise, proportional lowering speed. This feature is vital for preventing sudden load shifts, reducing shock to the chassis, and enhancing overall operational safety, especially when unloading on uneven ground. This precise dump body control ensures material is placed accurately and minimizes the risk of accidents, protecting both the driver and the vehicle.
Built for longevity, this valve boasts outstanding contamination resistance and a wide operating temperature range from -20 to 80°C. The internally developed relief valve offers a high pressure opening ratio and superior sensitivity. Combined with the anti-corrosion electrophoretic coating on the valve body, these features guarantee that our tipper truck hydraulic valve withstands the test of time, even in the most challenging and polluted job sites. This results in reduced maintenance costs and greater operational uptime for your fleet.
Designed to work seamlessly with standard commercial vehicle pneumatic systems (0.6-1 MPa control pressure), this valve ensures effortless and reliable operation. The optimized pneumatic piston actuates the spool accurately for smooth transitions between lifting, holding, and lowering functions. This integration simplifies the dump truck hydraulic system design and provides the driver with a responsive and intuitive control experience, reducing operator fatigue and ensuring consistent, reliable performance shift after shift.
② Check the Interface: For most standard domestic or retrofit applications, a general-purpose interface (like our 4HT series) is the best fit. However, if you are operating imported chassis or high-standard mining trucks, we recommend a valve with an SAE flange interface (like our HT-SAE series) for superior compatibility.
③ Check the Flow Rate: Light to medium-duty trucks (10-20 tons) typically require a flow rate of around 150 L/min. For heavy-duty mining dump trucks requiring faster lifting speeds, a high-flow valve (e.g., 220 L/min) with a dual-circuit design is essential.
Not sure which one to pick? Simply send us a photo of your old valve’s nameplate or your hydraulic cylinder. Our engineers will match the exact model for you for free.
① Single-Acting Valve (e.g., 4HT-150-01): This is the most cost-effective solution. It features a simpler structure and is designed to control a single lifting cylinder. It is perfect for standard rear-dump trucks.
② Dual-Circuit Valve (e.g., HT-SAE-1150): This offers higher safety and stability. If your vehicle operates in harsh conditions (like mines) or requires synchronized control of multiple cylinders, the dual-circuit design provides stable support and prevents tipping risks caused by single-line failure.
① Specialized Expertise: We focus exclusively on hydraulic systems for dump trucks. Our product line covers everything from light-duty to heavy-duty mining applications.
② Customized Service (OEM/ODM): We go beyond standard products. Whether you need specific mounting dimensions or custom branding, we offer deep customization to meet your exact requirements.
③ Factory Direct Quality: As a manufacturer, we provide you with exclusive discounts and strict quality control. Every valve undergoes rigorous pressure and sealing tests before shipment—we never sell refurbished parts.
