      • Product Introduction
      • Service Promise
      • Ordering Process

      The 800X differential pressure bypass balance valve is a kind of valve that balances the pressure difference between the supply and return water of the air conditioning system. Differential pressure by-pass valve can improve the utilization rate of the system, maintain accurate pressure difference straightening each other, and minimize the noise of the system, as well as damage to equipment caused by excessive pressure difference. The 800X differential pressure balance valve is superior to other balancing valves in that it has no actuator, and the pressure difference of the medium itself can achieve the function of balancing system, save energy and installation space. It is an intelligent valve.

      Performance characteristics

      1, constant valve ends and controlled system pressure difference, to support user system variable flow operation.

      2, automatic work depends on pressure difference without external power.

      3, can directly show the control pressure difference.

      4, can directly set the control pressure difference.

      5, control differential pressure adjustment is sensitive, simple operation.

      6, medium temperature: 0~150 C.

      7. Adjustable range of pressure control: 0.05~0.6Mpa

      8. The error of control pressure difference is less than or equal to 5%.

      Main uses

      Normally closed by-pass pressure difference control valve is used between fuel and gas heat source supply and return pipes, central air conditioning distributors and water collectors. As a primary flow measurement, secondary side variable flow system by-pass installation can effectively protect fuel and gas units from excessive temperature damage caused by flow too small, can effectively protect cold water. The unit is damaged by local freezing caused by too small flow.

      Normally open by-pass pressure difference control valve is used in central heating system with large height difference and high heat source. 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 proper position of the return pipe in the low area. The pressure of the return pipe is adjusted and set by adjusting the valve. It can not only ensure that the users in the high area will not empty, but also protect the equipment in the low area from damage due to high pressure.
