the Selection Criteria of Check Valves

图片
As a  Flange Check Valve Manufacturer , share with you. Swing Check Valve   1. In order to prevent the medium from flowing backward, check valves should be installed on equipment, devices and pipelines; 2. The check valve is generally suitable for clean media, and should not be used for media containing solid particles and large viscosity; 3. Generally, horizontal lifting check valves should be used on horizontal pipes with a nominal diameter of 50mm; 4. straight-through lifting check valve can only be installed in horizontal pipelines; 5. For the inlet pipeline of the pump, a foot valve should be selected. The foot valve is generally only installed on the vertical pipe of the pump inlet, and the medium flows from bottom to top; 6. Lifting type has better sealing performance than swing-opening type, and has larger fluid resistance. It should be installed on horizontal pipelines horizontally and vertically on vertical pipelines. 7. The installation position o...

Dynamic Flow Control Valve

Dynamic Flow Control Valve Performance and characteristics of self-operated flow control valve 1.The flow can be set according to the design or actual requirements, which can automatically eliminate the pressure fluctuation of the system and keep the flow unchanged. 2.Overcome the uneven heating and cooling of the system and improve the quality of heating (cooling). 3.Thoroughly resolve the contradiction between large proximal pressure difference and small distal pressure difference. 4. Reduce the amount of water circulating in the system and reduce system resistance. 5. Reduce the design workload, without the need for tedious hydraulic balance calculations on the pipe network. 6.The layout of the pipeline network is simple, and it is not necessary to use the same layout method to reduce the cost of the pipeline network and the maintenance costs. 7.Reduce the difficulty of network adjustment and change the complicated network adjustment work into simple traffic distr...
