Changzhou LangO Machinery and Technology Co.,Ltd is a professional lubrication pump manufacturer and exporter in china, that is concerned with the design, development and production of lubrication equipment.
Type YZF-L4 pressure control valve is a signal sending unit employing pressure difference signal to translate to electric signal through mechanical transmission which is installed on the end of two main pipelines of motor driven terminal type grease concentrated lubricating system. If the end pressure exceeds the set pressure value of the valve when the main pipeline is supplying grease, the valve will send a signal to electric control cabinet. Alternative grease supply of the two main pipelines can be realized by using electromagnetic reversal valve. The signal sent by the valve is correct and reliable. The set pressure value can be adjusted.
Nominal pressure (MPa)
Setting pressure (MPa)
Pressure adjusting range (MPa)
Loss flow (ml)
Use grease with cone penetration 265~385(25℃，150g) 1/10mm (NLGI0#~2#).
1. Pressure control valve should be installed on the end of the two main grease supply pipelines of terminal type system.
2. A grease feeder should be mounted behind of pressure control valve for the purpose of updating the lubricating grease in the valve.
3. The distributor behind of valve can be led out by connecting an inner joint and tee joint at the pressure gauge interface of valve body.
4. The set pressure can be adjusted lower by rotating the screw rightward, and higher leftward.
