Pressure Relief Valve
Poppet Type, Direct Acting
Metric Cartridge – 48 bar
DB10120A-13X
60 l/min
48 bar
The pressure relief valve DB10120A-
13X is a direct-acting, spring-loaded
poppet valve. If the hydraulic pressure
is below the pre-set spring tension, the
valve is closed. If the hydraulic pressure
exceeds the pre-set spring tension, the
valve opens and the oil can ow to tank
via port 2
