DIN Cast Steel Single Plate Wafer Type Check Valve

Introduction
DIN cast steel single plate wafer check valve is installed on one-way flow pipelines. It is mainly made up of valve body, disc and spring. This single plate check valve is used to prevent backflow and leakage of medium, and reversal of pump and driving motor. This cast steel check valve can also be installed in auxiliary pipeline system to balance system pressure.

Application
DIN cast steel single plate wafer check valve can be widely applied in tap water, sewage, construction, petroleum, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy, and other pipeline systems.

Features of Single Plate Check Valve
1. Disc is with high strength and stiffness.
2. CNC processing technology is adopted to produce disc.
3. Integral structure of this cast steel check valve is simple and compact.
4. DIN cast steel single plate wafer check valve can be installed in horizontal or vertical section of pipes and installation is very easy.
5. Small friction between sealing surfaces ensures low wear rate of sealing component.
6. Precision casting technology is adopted for manufacturing valve body.
7. CNC processing technology is adopted to produce disc.
8. Disc restrainer is designed to prevent that the open position of disc is too high to be shut down.
9. Two times shot blasting processing of valve surface make DIN cast steel single plate check valve look fine and smooth.
10. The disc sealing surface can be customized. Customer can choose sealing material for disc sealing surface according to needs.

Working Principle of Single Plate Check Valve
DIN cast steel single plate wafer check valve allows medium to flow through in only one direction, and prevents reverse direction flow. 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.
