OneProduct uses
FR-YC Differential Pressure SwitchSeries of adjustable differential pressure controllers are commonly used in water systems of central air conditioning to control the differential pressure between water supply pipes and return pipes.
TwoWorking Principle
FR-YC Differential Pressure SwitchIt is a pressure control instrument that drives the micro switch to work by means of elastic element. The controller has the characteristics of reasonable structure, accurate action, reliable use, high frequency of opening and closing, anti-vibration and large contact capacity.
Unlike other types of differential pressure controllers, it has a single-pole double-throw floating contact. Through the action of floating contact, the contact plate is connected to enable the motor driver to operate the valve.
A typical application example is to install the valve in the bypass pipeline near the system pump when the pressure difference between the system supply and return pipes exceeds the set value of the controller.The valve opens wide and more water flows through the bypass valve, which reduces 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.
ThreeProduct characteristics
1. FR-YC Differential Pressure SwitchThe utility model is a safety switch, which can be used to protect the refrigeration compressor from damage caused by too low lubricating oil pressure. If the oil pressure is too low, after a period of time, the controller will stop the compressor.
2. It can be used not only in refrigerants with Freon as medium, but also in air and liquid; (Allowable liquid temperature: -45 ~120 ~C)
3. The pressure difference setting value of the controller is adjustable.
4. Novel micro-switch ensures reliable conversion function.
5. Smart installation board, suitable for different occasions;
6. It can be used in water system to achieve a constant flow by controlling the pressure difference between the inlet and outlet of pipeline.
7. Because the controller bears high working pressure, it can be used as the oil pressure protection device of screw refrigeration compressor.
8. No delay device differential pressure controller (cooling water); differential pressure switch with time device (oil pressure protection);
9. The maximum working pressure of the controller is 33bar, which can be used as oil pressure protection and oil filter blocking protection for screw refrigeration compressor.
10. FR-YC Differential Pressure SwitchThe micro switch structure ensures reliable and fast conversion function.
11. If the system is used for corrosive media of phosphorus bronze, please put it forward to the manufacturer when ordering, and we will recommend the applicable model.
12. FR-YC Differential Pressure SwitchCan replace imported productsJOHNSON, DANFOSS, SAGINOMIYA, 3S, RANCO, etc.

Note: There are two types of protection for the differential pressure controller. One is to disconnect when the differential pressure is less than the set one, and the other is to disconnect when the differential pressure is greater than the set one.
