Wholesale HVAC System Oil Differential Pressure Switch

Oil differential pressure switches are pressure differential switches which normally used in water or oil fluid to control the pressure differential of the outlet tube and inlet tube. Bellowing is one of the typical application: install the valve in the pipeline which near the water(oil) pump, when the pressure differential of the two sides of the system increasing or decreasing and exceed the setting value, the valve will open. 

Then the system pressure differential will reach to the normal circulate. Both two sides of LF5D series have a high sensitive components, the switch will act to control the system of the equipment such as motor driven valve while the pressure differential changes.
