800X Pump Control Valve Differential Pressure Control Valve

800X Pressure Differential Side Balance Valve

1. PRODUCT PROFILE

The 800x pressure differential balance valve is a valve used for air conditioning system supply/backwater to balance differential pressure. The valve can improve the utilization of the system. Keep the differential pressure precise and constant, and minimize the noise of the system and the damage caused by excessive pressure difference. 800 x differential pressure balance valve is superior to other balancing valve is not executing agency, completely depends on the pressure difference between the medium itself to balance system function, save energy and installation space, is a kind of intelligent valve.

2. Performance characteristics

· Constant valve ends and controlled system pressure difference, to support user system variable flow operation.

· Automatic work depends on pressure difference without external power.

· Can directly show the control pressure difference.

· Can directly set the control pressure difference.

· Control differential pressure adjustment is sensitive, simple operation.

· Medium temperature: 0~150 C.

· Adjustable range of pressure control: 0.05~0.6Mpa

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

3. APPLICATION

· 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.
