Doosan DX180LC Manual Instruction Extract:

 

Add-on Main Relief Valve Operation
1. This relief valve is inserted between the neutral path “HP” and the tank path “LP”. Oil is filled into the inner space (C) through the orifice of the main poppet . The sleeve (2) and main poppet (1) are securely seated by the areal difference between “A” and “B”.
2. When the pressure in the neutral path “HP” reaches the preset pilot spring force, the pilot poppet (3) will be opened.
Oil flows around the pilot poppet (3), through the drill hole (E) and circular gap (D), and is guided to the tank path “LP”.
3. When the pilot poppet (3) is opened, the pressure in the inner space (C) is decreased to open the main poppet (1). Therefore, the oil in “HP” flows directly through path “LP”.
