I.Conditions of Use

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

II.Technical Parameters

Grease with a penetration of 265 to 385 (25 ° C, 150g) 1 / 10mm grease (NLGI 0 # to 2 #).

V.Instructions for use

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

2. When two YK F-L31 pressure control valves and one YH F-L1 hydraulic directional valve are used in combination, dry thin oil lubrication should connect the control line connection A of one pressure control valve with the other The control valve connection B of the control valve is connected with a pipe.

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

4. When fueling, 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 return main pipe opening to the oil reservoir.
