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.
