Pressure regulators are used to control and regulate the compressed air in pneumatic systems. They reliably protect against the maximum permissible pressure being exceeded or they limit the working pressure in a pneumatic system. Festo has three different pressure regulators for a wide range of requirements.
Our mini pressure regulator type LR-3,3 keeps the working pressure constant regardless of pressure fluctuations in the network and general air consumption, i.e. it reliably regulates the operating pressure completely independently of any fluctuations in the input pressure. The LR-3,3 is a directly operated diaphragm control valve with secondary exhausting, and can be mounted on a sub-base in any installation position. It can be used at a maximum output pressure of 8 bar in a temperature range from -10 to +60 °C and, at only 0.050 kg, is one of our most lightweight pressure regulators.
