LF5D series differential pressure switch/pressure control, normally use in water, oil series control difference of the outlet tube and inlet tube. One typical application is, put valve install in the next to water (oil) system pumps by-pass valve line, when the pressure difference rise (or reduce) of two sides of the tube of the system exceeds the setting data of the pressure control, so the valve open big (or close small), so the system tubes two sides pressure difference is to reduce, to reach the system normal circulate.
LF5D series differential pressure controls two sides have a high-sensitive part each other, when the pressure of two sides of the parts changes, it will let switch institution action to control systems equipment, such as motor drives valve.
