DIN Cast Steel Lift Wafer Type Check Valve
Description
DIN cast steel lift wafer check valve is installed in various pipeline, such as tap water, petroleum, sewage, construction, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, and other pipelines. It can be installed on both horizontal and vertical pipes. This cast steel check valve is used to prevent reverse flow and leakage of medium as well as reversal of pump and driving motor. It can also be employed to balance the pressure between main pipe system and auxiliary pipe system. This valve is mainly composed of valve body, disc, bonnet and gasket.
Features
1. DIN cast steel lift wafer check valve has characteristics of sensitive movement, good sealing property, high reliability and long serve life.
2. CNC technology is adopted for producing disc.
3. Disc restrainer is designed to avoid that disc is too high to be closed.
4. Disc closes fast with little water hammer pressure generated.
5. Two times shot blasting on valve surface ensures beautiful appearance of the cast steel check valve.
6. Flow channel inside t DIN cast steel lift wafer check valve is unobstructed, so fluid resistance is small.
7. Small friction between sealing surfaces assures low wear rate of sealing surface.
8. Sealing surface can be customized according to customers’ requirement.
Working Principle
DIN cast steel lift wafer check valve is installed in one-way flow pipeline. It allows medium to flow through the valve in only one direction, and prevents reverse direction flow. Valve disc opens and closes automatically depending on force from media flowing. Disc will open under the pressure of forward flow fluid. When fluid flows in reverse direction, the disc will be closed by fluid pressure and dead weight so as to cut off the flow.

- DIN Stainless Steel Swing Type Check ValveDIN stainless steel swing check valve is installed on one-way flow pipelines. It is used to prevent backflow and leakage of medium (such as fluid, gas, etc.), and reversal of pump and driving motor. This stainless steel check valve can also be installed in auxiliary pipeline system to balance system pressure. DIN swing check valves are widely applied in tap water...
