Single Plate Check Valve Design Characters:

  1. Shorter Face-to-face dimension, lighter in weight
  2. More easy and quick to be shut off.
  3. Swift check valve is suitable for both horizontal and vertical pipe lines easily.
  4. Less resistance force and perfect sealing performance.
  5. Applicable to harsh working condition, such as high temperature, high pressure conditions.
  6. Metal to Metal sealing workable for -40~+500 degree C.
  7. The higher working pressure, the better sealing performance.
