1. Hydraulic relief valve block uses the principle of pressure reduction when oil passes through the gap to keep the outlet oil pressure stable and low.
2. The pilot pressure reducing valve consists of a pilot valve and a main valve. The pressure flows out from the oil inlet of the main valve and then flows out from the oil outlet.
3. When the outlet pressure is higher than the set pressure of the pilot valve spring, the pilot valve opens, the main valve core rises, the X opening is the smallest, the outlet pressure drops, and the pressure is reduced.
4. The hydraulic balance valve block can set the pressure ratio to 1.5:1 3:1 4.5:1.
