Description
DIN stainless steel lift wafer check valve is made up of valve body, disc and spring. It is installed in tap water, petroleum, sewage, construction, chemical, food, medicine, textile, electric power, shipbuilding, metallurgy and other pipeline systems. This type of lift check valve can be installed on both horizontal and vertical pipes.
Functions
1. DIN stainless steel lift wafer check valve is used to prevent reverse flow and leakage of medium as well as reversal of pump and driving motor.
2. It can also be employed to balance the pressure between main pipe system and auxiliary pipe system.
Advantages
1. DIN stainless steel lift wafer check valve has characteristics of sensitive movement, good sealing property, high reliability and long serve life.
2. High strength solid axis pin is installed to guarantee valve’s long service life and excellent performance.
3. Small friction between sealing surfaces assures low wear rate of sealing surface.
4. Sealing surface can be customized according to customers’ requirement.
5. Our lift check valves have passed DIN and CE certifications.
Features of DIN Stainless Steel Lift Wafer Check Valve
1. Flow channel inside the valve is unobstructed, so fluid resistance is small.
2. CNC technology is adopted for producing disc.
3. Disc closes fast with little water hammer pressure generated.
4. Disc restrainer is designed to avoid that disc is too high to be closed.
5. Two times shot blasting on valve surface ensures its beautiful appearance.
Working Principle
DIN stainless 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.
