Secondary pressure control circuit

Secondary pressure control circuit refers to the pressure regulating circuit at the air source inlet of each pneumatic equipment. As shown in the figure, the relief valve is mainly used to adjust the pressure. Generally, the water separator, air filter, pressure reducing valve and oil mist separator are called pneumatic three parts (which can be made into joint parts). If there is no need for lubrication in the pneumatic system, the oil mist eliminator may not be used.

Including: 1 - water separator, 2 - pressure regulating valve, 3 - oil mist separator, 4 - pressure gauge
