We use the simulator simulation and physical test methods for research, the vave in the hydraulic drills by more than half the actual working conditions (flow rate 80L/min, working pressure 21MPa, 22MPa, two regulating valves two points) assessment, the valve has been stable and reliable work, for use in the field has brought great convenience, not only because of the small valve size, light weight, no leakage, small size, the host of the larger operating space, and it reduces maintenance times and instability due to pressure caused by other failures, thus improving operational efficiency and boring cycle rate.
The technical information of cartridge type hydraulic pressure release valve:
Max. operating pressure: 300 bar
Setting pressure: 160bar
Rated flow capacity: 68 L/MIN
Internal leakage: ≤30ml/min
Recommended filtration: 25 MICRON
Hydraulic fluids: Mineral Oil, Viscosity 10 - 400 cST
Temperature range: -30° C to +110° C
Note: For extension of the service life, It is better to use the condition where is no gas or dust in ambient which can corrupt metal or destroy nonconductor
