Hydraulic Safety Valve Balance Valve for Aerial Work Vehicle
When a hydraulic system uses single acting cylinders, it requires a mechanism to direct fluid flow in one direction while allowing unrestricted flow in the opposite direction. This vital function is efficiently performed by single-balance valves.
The core function of a single-balance valve is load-holding. By preventing backflow when pressure exceeds pre-set limits, it ensures that loads are held securely in position without drift or unintentional movement. This feature is essential for precision applications such as cranes, lifts and presses.
Single balance valves can be set to specific pressure settings tailored to system requirements via their pilot-operated relief valves. This customisation accommodates varying loads and operating conditions, ensuring optimum performance.
In essence, single balance valves are critical components designed to provide precise control of movement within hydraulic systems that utilise single acting cylinders. They offer robust load-holding capabilities while ensuring safe operation by preventing backflow under excessive pressure.
