Direct Acting, Poppet Type, Metric Cartridge - DB10120A


The pressure relief valve DB10120A is a pilot-operated, spring-loaded poppet valve.

Its function is to relieve pressure on the system and close is its normal position. Therefore, if the pressure at port 1 exceeds the preset spring tension, the pilot stage opens and oil flows from behind the main piston to tank port 2. Then, the resulting differential pressure causes the main piston to move against the return spring and allows the oil to flow from port 1 to port 2.

This continues until the system pressure is equal to the spring tension and the valve closes again.
