|---|---|
Suitable for agricultural light truck dump truck hydraulic system, can match double multistage cylinder or single rod piston cylinder, lift, drop and slow drop, internal safety relief valve, system pressure can be set. Can use the control valve, remote gas control reversing control.
Built-in System Protection: Includes an adjustable pressure relief valve. If the truck bed is overloaded or hits an obstruction during lifting, the valve bypasses fluid back to the reservoir to prevent lines from bursting.
Open-Center Hydraulic Design: Designed specifically for open-center systems and single-acting oil cylinder layouts, allowing oil to circulate back to the tank freely when the valve is in neutral/idle.
Remote Pneumatic Shifting: Relies on a cabin-mounted air control switch (like the Q23 series) to safely actuate the internal hydraulic spool from a distance

Applications
It is widely used in mini-tippers and light commercial dump trucks (typically 2-ton to 5-ton load capacities).
It controls the single-acting telescopic cylinders that lift the dump bed to unload gravel, sand, or construction debris.
Agricultural Tricycles & Small Tractors: Commonly installed on motorized three-wheelers and small utility tractors equipped with tipping beds [临沂金利液压].
Silage & Grain Trailers: Used to manage the hydraulic tipping mechanisms of specialized farm trailers that dump harvested crops or animal feed.
Mini Garbage Collection Trucks: Controls the lifting and tilting mechanism of small waste containers.
Light Highway Maintenance Tippers: Powers the bed lift on asphalt or tool-carrying service trucks.
Site Dumpers: Used in compact, articulated site dumpers that move earth across tight construction zones.
Light Scissor Lifts / Tipper Attachments: Can be adapted to control basic lifting attachments on skid-steer loaders or utility vehicles.
QHF34-E15L-Light Truck Directional Valves are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
Answer: "E" indicates the valve's pressure rating capability (up to 25MPa), while "15" typically represents the nominal thread port sizing or internal core configuration diameter. The "L" refers to threaded connection configurations.
Answer: No. The QHF34-E15L is specifically configured for single-acting cylinders (common on small tipper trucks). It pushes oil out to lift the bed under pressure but relies on the gravity/weight of the bed to push the oil back through the valve when lowering.
Answer: If the bed sags during mid-stop, there is an internal pressure leak. This is usually caused by a compromised internal seal or scratches/debris stuck on the spool bore, allowing hydraulic oil to weep back into the return line.
Answer: Since this is a pilot air-driven valve, check your truck's air supply lines. If the control air pressure falls below 0.6 MPa, or if there is an air leak in the lines leading to the valve head, it will not generate enough force to overcome the internal spring and shift the oil spool.
Answer: Yes, it features an integrated adjustable relief valve. If your truck struggles to lift its rated maximum weight, the relief valve can be carefully calibrated to safely match your truck's optimal hydraulic operating limit without bypassing too early.
