Application Information

• Why does the flow rate need to be above 5 feet per second through a swing check valve?

  A swing check valve design relies on the disc being held against the upper part of the valve body when the check valve is in the open position, to prevent the disc from fluttering in the flow of media. Flow rates below 5 FPS will typically not hold the disc firmly against the body.
  
  

• What is water hammer?

  Water hammer, also known as hydraulic shock, is a phenomenon that occurs when a fluid in motion is suddenly forced to stop or change direction. This abrupt change causes a pressure surge or wave in the piping system, which can lead to loud banging noises, vibrations, and even damage to pipes, fittings, or equipment.
