800XDifferential pressure bypass balance valve is a kind of valve used to balance the pressure difference between supply and return water of air conditioning system. 800X differential pressure bypass balance valve can improve the utilization rate of the system, maintain the accurate mutual alignment of pressure difference, and 520 pressure reducing and holding valve (1) can greatly reduce the noise of the system and damage to the equipment caused by excessive pressure difference.

800XDifferential pressure bypass valve is a kind of valve used to balance the pressure difference between supply and return water of air conditioning system.
The differential pressure bypass valve can improve the utilization rate of the system, maintain the accurate constant value of the differential pressure, and 520 pressure reducing and holding valve (1) can greatly reduce the noise of the system and damage to the equipment caused by excessive pressure difference.

800XThe advantage of differential pressure balance valve is that it has no actuator. JD745X multi-function water pump control valve completely relies on the pressure difference of medium itself to achieve the function of balance system, saving energy and installation space. It is an intelligent valve.

 

The normally closed bypass differential pressure control valve is used for the water supply and return pipes of fuel oil and gas heat sources, and between the water distributors and collectors of central air conditioning. It is used as the bypass installation of primary flow measurement and secondary side variable flow system, which can effectively protect fuel oil, gas and water
The gas turbine will not be damaged due to too high temperature caused by low flow, which can effectively protect the water chiller from local freezing caused by too small flow.

The normally open bypass differential pressure control valve is used in the central heating system with large height difference and heat source in high area. The pressure difference of the valve is set according to the height difference, and the pressure reducing pump and check valve are installed at the appropriate position of the return water pipe in the low area,
The return water pressure reducing device composed of regulating valve can adjust and set the pressure of return water pipe through the regulating valve, which can not only ensure that users in high area will not empty, but also protect equipment in low area from damage due to high pressure.

Constant pressure difference between both ends of valve and controlled system to support variable flow operation of user system;
It can work automatically by pressure difference without external power;
It can display the control pressure difference directly;
It can directly set the control pressure difference between 0 ℃ and 150 ℃;
The control pressure difference is sensitive and easy to operate;
Medium temperature: control differential pressure, adjustable range: 0.05 ~ 0.6MPa
The control pressure difference error is less than ± 5%;
