LF5D series differential 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 side of the systems tube exceed the setting data of the pressure control, so the valve open big (or close small), so the system tubes two sides pressure difference is reduce, to reach the system normal circulate. LF5D series differential pressure controls two side have a high-sensitive parts each other, when the pressure of two side of the parts change, it will let switch institution action to control systems equipment, such as motor drives valve. LF55 Series pressure switches is usually used with fluorinated refrigerants to control the pressure of compressor in refrigeration system. It can also used in air and water. Internal Micro-swith ensures reliable switching. It is provided standard Mounting Bracket. Model Specification
