The compact Marco control block for hydraulic functions provides a very high flow rate despite its small size. It includes a dynamic pressure limitation valve as well as the required filters and pressure protection. The integrated dynamic pressure limitation valve opens the return flow to the outside if it exceeds 80 bar at an operating pressure of 350 bar. The patented valve reduces the pressure limitation limit in the supply line if the pressure level should drop. If there is no supply pressure, this safety valve opens at 10 bar. Accidental opening of non-lockable functions can therefore not take place.
