Working Principle
_/
_/
_/Pressure switch
_/ uses the action of elastic elements to drive micro-movements Pressure control instrument for switch operation. The controller has the characteristics of reasonable structure, accurate action, reliable use, high opening and closing frequency, vibration resistance and large contact capacity.
_/It is different from other models of differential pressure controllers in that it is equipped with a single-pole double-throw floating contact. Through the action of the floating contact, the contact plate is connected, allowing the motor driver to operate the valve.
_/A typical application example is to install the valve in the bypass line near the system water pump. When the pressure difference between the system supply and return pipes exceeds the set value of the controller,
When the valve is opened wide, more water flows through the bypass valve, reducing the pressure difference between the supply and return pipes of the water system. On the contrary, the pressure difference between the supply and return pipes of the water system increases.

Product Features
_/
_/Differential pressure switch
_/ is a safety switch that can be used to protect refrigeration The compressor is protected from damage due to low lubricating oil pressure. If the oil pressure is too low, the controller will stop the compressor after a period of time.
_/
_/Not only suitable for refrigerants using Freon as the medium, but also for air and liquid (allowable liquid temperature
℃~+
℃)
_/
_/The pressure difference setting value of the controller is adjustable
_/
_/The novel micro switch ensures reliable conversion function
_/ < br/> _/Smart mounting plate, suitable for different occasions
_/
_/Can be used in water systems to achieve a constant flow rate by controlling the pressure difference between the inlet and outlet ends of the pipeline.
_/
_/Because the controller withstands high working pressure, it can be used as an oil pressure protection device for screw refrigeration compressors
_/
_/No delay device pressure difference Controller (cooling water) with time device differential pressure switch (oil pressure protection)
_/
_/Maximum working pressure of the controller
Can be used as oil for screw refrigeration compressors Pressure protection and oil filter clogging protection device.
