For hydraulic systems and lubrication systems, we have a comprehensive range of high-pressure filters in our product portfolio. These are available in various designs and dimensions and for different pressure ratings. A cold start valve can be integrated in the filter head of the Pi 4000. It ensures that only filtered fluid is supplied to the hydraulic system in all operating states.
If the differential pressure rises above the opening pressure of the cold start valve (e.g. due to excessive viscosity of the fluid during a cold start or if the element has not been changed), a partial flow is returned to the hydraulic tank via the tank connection on the filter head. The robust housing can withstand strong operating pressure, while the streamlined designs also ensuremaximum performance. The filter elements are classified according to DIN 24550.
