Direct Acting, Poppet Type, Metric Cartridge – DB12120A-CE
The pressure relief valve DB12120A-CE is a direct-acting, spring-loaded poppet valve with CE mark and TÜV SV.
Its function is to relieve pressure in the system. The spring exerts a force on the poppet and presses it on the valve seat. 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. To ensure that stable operation is maintained, the poppet is securely located in the damping piston which produces a damping force, opposing the direction of movement, and this has a stabilizing effect.
