Direct Acting, Poppet Type, Metric Cartridge – DB4E

Relief valve DB4E

The pressure relief valve DB4E is a direct-acting, spring-loaded poppet valve. Its function is to relieve pressure on the system.

The spring exerts a force on the poppet and presses it onto the valve seat. If the hydraulic pressure is below the preset spring tension, the valve is closed. When the hydraulic force exceeds the preset spring tension, the valve opens and allows flow to the tank via port 2.
