ANSI 600LB API 6D Flanged Check Valve , Swing Type Industrial Check Valve

Product Description:

1. It is used to prevent fluids from flowing back, when the inlet pressure is lower than the outlet pressure, the valve will automatically shut down to protect the pipe system.
2. The products feature a reasonable structure, reliable seal, good performance and nice modeling.

3. Either soft or hard seal can be selected for the product upon different working conditions. The sealing face is buit up with Co-based carbide alloy, leaving a better wearability, corrosion and scrap resistance and a longer duration.

4. Small opening pressure, the disc can be opened fully with a very small pressure differential.

5. Inside-set bolt-bearing structure reduces leakage and reliable use.

6. PN≥ 16.0MPa(Class1500), the middle cavity uses a self- tightening sealing structure to have the sealing performance reinforced along with the pressure rise so as to ensure

   the sealing performance.

7. Differnt parts materials and different sizes for flange, butt-welding are available for sensible combination according to different working facts and customers' requirements.
