1. Conditions of use

The pressure control valve is used in combination with the hydraulic reversing valve or pressure control valve in the two-line centralized lubrication system to increase the pressure in the pipeline. It can make the oil supply branch pipe relatively slender, the distributor can be centrally arranged, and the action is reliable. Expand the lubrication range. At the same time, it makes daily inspection work convenient. This valve is more suitable for secondary distribution systems. It increases the oil supply pressure of the primary distributor, allowing it to reliably perform secondary distribution.

5. Instructions for use

1. Connect the outlet to the oil return port of the hydraulic reversing valve or the oil inlet of the pressure control valve within 1 meter in the direction of the arrow.

2. When using two YK F-L31 pressure control valves and one YH F-L1 hydraulic directional valve in combination,Dry thin oil lubricationThe control pipeline interface A of one pressure control valve and the control pipeline interface B of the other pressure control valve should be connected by piping.

3. Combination of two YKF-L31 type hydraulic reversing valves and one YHF-L1 type hydraulic reversing valve; combination of one YKF-L32 type and one YHF-L2 type hydraulic reversing valve or YKF-L4 pressure control valve.

4. When supplying oil, the relationship between the inlet pressure P1 and the outlet pressure P2 (the setting pressure of the hydraulic reversing valve or pressure control valve) is: P1=3P2-P3. P3: Residual pressure in the main oil return line open to the oil reservoir.
