Wafer Type Check Valve


Wafer Type Check Valve


Description of Wafer Type Check Valve:

Wafer check valves are named for their compact size. The small size of the valve enables it to be set between a set of flanges. Flanges are materials designed to connect pipes, valves, and various piping equipment for the purpose of creating a piping system. They help to provide quick access in case cleaning or other maintenance is needed.

Features of Wafer Type Check Valve:

  1. Disc travel is short with less impact force caused by valve closing;
  2. The disc closes quickly with less water hammer pressure. Water hammer pressure is only 1/2 to 1/5 times of flange type swing check valve and flange type lift check valve;
  3. Low flow resistance;
  4. Horizontal and vertical installation available;
  5. Very low opening (cracking) pressure differential;
  6. More reliable due to lower impact forces, and less water hammer.
