Wholesale Semi-trailers Tractors Load Sensing Valves

Semi-trailers Tractors Load Sensing Valves Manufacturers

The load sensing valve (L.S.V.) serves the purpose of automatically adapting the brake pressure and therefore the brake force according to the load of the vehicle. Automatic load-dependent brake force regulation is compulsory for semi trailer tractors with a permissible total weight of more than 7.5 t and semi-trailers with the sum of the permissible axle loads greater than 7.5 t . EC regulations (RKEG 74/132 EWG) as well as the ECE stipulation No. 13 specify automatic brake force regulation for all motor vehicles and trailers with a total weight exceeding 3.5 t provided brake force regulation is necessary.

The Function and Operation of Load Sensing Valves in Semi-Trailers: A Comprehensive Overview


Load sensing valves are hydraulic control valves that regulate the brake pressure of semi-trailers based on the weight of the load being carried. The primary function of load sensing valves is to maintain the required braking force on the trailer wheels, regardless of the weight of the cargo being carried.
Operation of Load Sensing Valves:
Load sensing valves work by detecting the hydraulic pressure in the trailer's brake lines. This pressure is proportional to the weight of the load being carried by the trailer. As the load increases, the hydraulic pressure in the brake lines also increases. Load sensing valves use this pressure signal to adjust the brake pressure applied to the trailer wheels.
When the trailer is empty, the load sensing valve reduces the brake pressure to the wheels, which reduces the braking force required to stop the trailer. This ensures that the brakes are not overly sensitive when the trailer is empty, which can cause the wheels to lock up and reduce the braking efficiency.
As the load on the trailer increases, the load sensing valve gradually increases the brake pressure applied to the wheels. This ensures that the trailer has enough braking force to stop effectively, regardless of the weight of the cargo.
The load sensing valve achieves this by controlling a valve that is connected to the trailer's brake system. The valve regulates the pressure of the brake fluid in the trailer's brake lines, which in turn adjusts the amount of braking force applied to the trailer wheels.

The Advantages of Semi-trailers Tractors Load Sensing Valves


Load sensing valves in semi-trailer tractors provide several advantages, including:
    Improved Safety: Load sensing valves improve safety by preventing the tractor from being overloaded, which can cause stability issues, accidents, and damage to the vehicle. Load sensing valves regulate the hydraulic pressure in the brake system to match the load, reducing the risk of brake failure and ensuring that the vehicle can stop safely.
    Fuel Efficiency: Load sensing valves can help save fuel by reducing the amount of pressure needed to operate the hydraulic system. This reduces the amount of energy needed to power the hydraulic system, which in turn reduces the amount of fuel consumed by the engine.
    Reduced Wear and Tear: Load sensing valves can help reduce wear and tear on the hydraulic system and other components of the tractor. By regulating the hydraulic pressure, the load sensing valve ensures that the system is not subjected to excessive force or pressure, which can cause damage to the system over time.
    Increased Productivity: Load sensing valves can increase productivity by allowing the tractor to operate at its maximum capacity while still maintaining safety and efficiency. By preventing overloading, the tractor can carry more weight without compromising safety or performance, which can lead to increased productivity and profitability.
    Improved Comfort: Load sensing valves can improve the comfort of the driver by providing a smoother ride. By regulating the hydraulic pressure, the load sensing valve ensures that the trailer is not subjected to sudden jerks or movements, which can cause discomfort and fatigue for the driver.
