Structural Characteristics Of Swashplate Anti Slam Check Valve

Structural Characteristics Of Swashplate Anti Slam Check Valve

Double eccentric disc, when closed, the valve acne gradually contacts with the sealing surface to achieve impact-free and noise-free work.

2. Micro-elastic metal seat, good sealing performance.

3. Butterfly disc design, switching fast, sensitive, long service life.

4. The swashplate structure makes the fluid passage streamlined, with small flow resistance and energy-saving effect.

5. Check valves are generally suitable for cleaning media, not for media containing solid particles and high viscosity.
