Data sheet ERHARD DVF pressure reducing valve

The directly controlled pressure reducing valve Pressure reducing valves such as the ERHARD DVF pressure reducing valve transform a higher, fluctuating inlet pressure into a lower, constant downstream pressure. The desired downstream pressure value is set by pretensioning the spring. There are two types of springs available for the ERHARD DVF pressure reducing valve: spring A (blue) for a pressure range of 1.5 to 6 bar and spring B (red) for a pressure ranging between 5 and 12 bar. When the downstream pressure drops below the preset value, the valve will open and when it exceeds the value, it...
