Leopard pressure reducer LEOPARD pressure reducing hydraulic diaphragm valve. Used in places where a diminution of the pressure is needed. Leopard Pressure reducing hydraulic valve Leopard pressure reducer valves are available from DN 20 to DN 300 diameter. Applications The pressure reducer valve is used in places where pressure is needed for: Adjust the pressure to consumption. Protect installations. The pilot acts on the valve so that it has a modulating function, in order to keep the downstream pressure constant for the setting value. Functioning The pilot sets the downstream pressure regardless the inlet pressure. If the outlet pressure is lower than the preset pressure the pilot will open the valve and it will act just when the outlet pressure exceeds the preset one. The reducer pilot must be adjusted regarding the installation needs. Turning the pilot screw clockwise you will reduce the outlet pressure. Turing the pilot anti-clockwise you will increase the outlet pressure. Maximum reduction ratio: inlet pressure x 1/3. For example, with a 6 bar inlet pressure the outlet pressure will be 2 bar. Working in pressure under 2 bar the valve will suffer cavitation complications. Precision ratio: preset pressure ±0,3 bar.
