Direct Acting, Poppet Type, Metric Cartridge - DB12120A-CE

POA

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 on the system. The spring exerts a force on the poppet and presses it on the valve seat. If the hydraulic pressure is below the preset spring tension, it closes the valve. Therefore, only if the hydraulic force exceeds the preset spring tension does the valve open and it diverts flow to the tank via port 2.

Moreover, to ensure the maintenance of that stable operation, the location of the poppet is safe and in the damping piston. So, it produces a damping force, opposing the direction of movement, and this has a stabilizing effect.

See datasheet for drawings, dimensions, model code, etc...

Caution: The valve DB12120A-CE is classified as a safety valve according to PED. Always follow the operating instructions supplied with the valve!

The key points are:
  • Tank pressure (port 2) must be p2 max = 0 bar!
  • If the connections are incorrect, the safety function of the valve is disabled!
  • Do not alter the pressure setting!
  • Do not tamper with the valve!
