Lefoo Boiler Pressure Switch LF56

Name: Boiler Pressure Switch LF56
Brand: LEFOO INDUSTRIAL CO.,LTD.
Rating: 4.8 (50 reviews)

LF56 series pressure switches are mainly used to control pressure of boiler or water tower regulating system. When the system pressure exceed the setting point, the switch will cut off the circuit for protection. With SPDT contact arrangement, LF56switch can detect the pressure change and shift the internal status accordingly to control the on/off of external circuits, which is available for the pressure control, limit and alarm of non-hazardous liquid, gas and steam.
