Lefoo HVAC Pressure Switch LF58

Name: HVAC Pressure Switch LF58
Brand: LEFOO INDUSTRIAL CO.,LTD.
Rating: 4.8 (50 reviews)

The function of the hydraulic pressure switch in the hydraulic system is to control and adjust the flow direction, pressure and flow of the oil in the hydraulic system, so that the actuator and the working mechanism driven by it can obtain the required direction of movement and thrust (torque) And movement speed (rotation speed), etc.

Through continuous efforts LEFOO pressure control tries to manufacture and launch the world's most innovative and sophisticated hvac pressure switch.

LF58 Dual pressure switches is usually used with fluorinated refriqerants to control the pressure of compressor in refrigerant system. It can also be used in air and water. It provide two pressure set points in one switch.
