Hydraulic systems are used in everyday equipment, as well as specialised industrial equipment operated specifically for lifting and transporting large loads. Farm, mining and construction industries all make use of equipment and vehicles that are fitted with hydraulic components. relief The design of the hydraulic systems follows a format, with the same components being use.
For this type of system to work the hydraulic oil needs to be put under pressure to either get a motor or cylinder to work. If this hydraulic oil is experiencing too much pressure due to a pump failure, the excess pressure needs to be released before any damage can occur. This is done with the use of a pressure valve.
Pressure relief valves limit the pressure created within a system to a set level. When this level is reached, the valve reacts and feeds the excess flow from the system to the tank. When the hydraulic oil reaches a dangerous level, the pressure relief valve opens the hydraulic system. If the valve does not react, or there is no valve in use damage can occur to the system by damaging hoses or hydraulically driven motors or cylinders. Some safety valves need to be replaced after one use, while others can be reused over again. If a pressure relief valve is activated during use of the hydraulic system, it is a sign that there is a malfunction somewhere in the system that needs to be attended to.
Adjustable relief valves are used in hydraulic systems that are part of a working system such as a hydraulic press. When pressing and bending different types of metals, different pressure settings need to be applied. Therefore, having an adjustable relief valve the operator is able to set the valve to the setting suitable for the metal being pressed. When this pressure setting is reached in the seal system, the hydraulic fluid is released back into the reservoir tank and reused, allowing for the pressure to be maintained at a particular gauge reading for the needed amount of force to be exerted to the cylinders.
Power Team SA stocks and supplies a range of quality valves, including pressure relief and adjustable relief valves. With decades of hydraulic experience Power Team SA is suitably qualified to provide suggestions on the best valve option for their customers based on specifications such as cylinder, pump and application. These valves offer benefits such as optimal fluid flow, correct fluid directional control, effective load and lowering functions, independent pressure control and cylinder sequencing in multi-cylinder applications.
