What's the difference between the check valve and the stop valve?
Check valve is also called check valve or one-way valve, single-phase closed, individual hydraulic control one-way valve, plug valve also has a combination of controllable changes.The cut-off valve has the possibility of variable flow, two-way action, throttling possible, there can be two-way closed applications.
Check valves are used to automatically stop liquid backflow,Stop valve is used in the pipeline to cut off the liquid feed, manual or motorized valve.
The check valve is not the same as the cut-off valve. The difference between them is mainly that the structure is very different.Check valve is a one-way valve, automatically prevent reverse flow of fluid, no knob, can not be artificial blocking forward flow.The valve has a knob, and the controller can control the forward flow. Because of its special structure, the fluid can not flow backwards even if there is no artificial valve.
