Check valve such as DIN Lift Check Valve is one of the commonly used valves, referring to the flow of the medium itself to automatically open, closed disc, used to prevent the medium flow back. As a China Industrial Valves Brand, We want to say Divided into several types, different check valves have different functions. Get to know today.

(1) lift check valve. The disc of swing check valve is like a disc, rotating around the axis of seat passage, because the valve inner passage into a flow line, flow resistance than the lifting check valve small, suitable for low flow rate and flow do not change the large aperture occasions, but should not be used for pulsating flow, its sealing performance is not as good as the lifting. There are three types of swing check valves: single valve type, double valve type and half valve type. These three types are mainly divided according to the valve diameter. The purpose of these three types is to prevent the medium from stopping the flow or reversing the flow to weaken the hydraulic impact.

(2) compression check valve. This valve is used for boiler water supply and steam cut-off. It has the integrated function of lifting check valve and globe valve or Angle valve.

(3) pipeline check valve. A valve that slides along the center line of the body. Pipeline check valve is a new valve, small size, light weight, processing technology is good, is one of the development direction of check valve. But the fluid resistance coefficient is slightly larger than the swing check valve.

In addition to these three, there are other types of check valves, if you want to know more welcome to contact us!We are Gost Globe Valve Supplier. Providing you with high quality services and products
