Introduction
DIN stainless steel single plate wafer check valve, also named reflux valve, is used to prevent backflow and leakage of medium, and reversal of pump and driving motor. This stainless steel 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. This single plate check valve can also be installed in auxiliary pipeline system to balance system pressure.
Application of Stainless Steel Check Valve
DIN stainless 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.
Advantages
1. Valve Body
Precision casting technology is adopted for manufacturing valve body.
2. Sealing
Small friction between sealing surfaces ensures low wear rate of sealing component.
3. Surface
Two times shot blasting processing of valve surface make DIN stainless steel check valve look fine and smooth.
4. Disc
1) CNC processing technology is adopted to produce disc.
2) Disc restrainer is designed to prevent that the open position of disc is too high to be shut down.
3) Disc of this reflux valve is with high strength and stiffness.
4) The disc sealing surface can be customized. Customer can choose sealing material for disc sealing surface according to needs.
5. Axis Pin
High strength solid axis pin is installed precisely to assure DIN stainless steel check valve’s reliable performance and long service life.
