HYDAC pilot operated pressure relief valves in poppet version are spring-loaded poppet valves which limit the pressure in hydraulic systems in the elevated performance range. Different pressure ranges enable an optimal system adjustmen
The pilot operated pressure relief valve VP-DBP10 is a leakage-free poppet valve - subplate mounted - used for limiting the inlet pressure by opening the outlet against spring force. Qmax = 200 l/min Pmax = 350 bar
The pilot-operated pressure relief valve VP-DBP10 in subplate design has a pilot
and a main stage – both are poppet-type.
Its function is to limit the pressure in the system. When the hydaulic force at port P
exceeds the pre-set spring tension of the pilot stage, the poppet opens and oil flows
from the rear side to the tank port. Due to the resulting pressure imbalance, the main
piston moves against the return spring and lets oil from port P to T.
This continues until the system pressure is equal to the spring pressure and the
valve closes again.
Attention: pressures at port T are increasing the opening pressure!
