Two Pump 'Hi-Low' Unloading Valves

Two Pump 'Hi-Low' Unloading Valves

Hydraulic two-pump Hi-Low unloading valves allow the smooth unloading of a low-pressure/high-flow pump into a suitable dual-pump high-low system. A suitable system is a hydraulic system which makes the most of two pumps as a means of providing rapid speed to a relevant actuator.

Hydraulic Two-Pump Hi-Low Unloading Valves

Once resistance is encountered, and the requirement of the fluid switches from a high speed to high force/torque, the low-pressure/high flow pump is unloaded back to tank at minimum pressure. All the available horsepower is directed to the hi-low pump.

Essentially, these models are used in a hydraulic system in which 2 parallel-working pumps are used to release the excess of the higher flow pump to the tank as soon as it reaches the required pressure setting. Typically, these models are made of zinc plated steel, and the very best models will offer no, or very limited, leakage of hydraulic fluid.
