VIS Hydraulics IRR0.M24

The IRR valve combines in one compact insert cartridge the typical function of shock relief valve and anticavitation through thecheck valve. In the pressure relief function it’s a side-in nose-exhaust valve, with very low pressure rise thanks to the smart deflectordesign. When the pressure at the high pressure inlet (2) reaches the valve setting, the valve starts to open to tank (1). In the freereverse flow function a very light bias spring allows for ease of flow passage from nose to side (1 to 2). High precision machiningguarantees quick response to load changes, limited hysteresis and reduced internal and external leakage.
