Direct Acting, Poppet Type, Metric Cartridge – DB3E

Relief-valve---DB3E

The pressure relief valve DB3E is a direct-acting, spring-loaded poppet valve. Its function is to relieve pressure in the system.

The spring exerts a force on the poppet and presses it on the valve seat. On the opposite side, the system pressure exerts force on port 1 of the valve. If the hydraulic pressure is below the pre-set spring tension, the valve is closed. Only if the hydraulic force exceeds the pre-set spring tension does the valve open and flow is diverted to tank via port 2.
