Piston / Lift Check Valves

Why Check Valves?

The main goal of a check valve is to keep medium flowing in the proper direction.  These must be installed per the arrow that is on the body to ensure the correct flow direction.  There are also other uses for check valves such as to prevent backspin, water hammer and thermoacoustic oscillations.

Advantages of Check Valves
  • Very low maintenance required
  • Effective method for preventing water hammer or thermoacoustic oscillations
  • Protection for pumps from reverse flow or pressure
  • low footprint, especially with wafer check valves
  • Open and close automatically as flow stops/starts
Disadvantages of Check Valves
  • Not recommended for use with constantly variable on/off due to wear on the seats or springs
Types of Check Valves Available
  • Swing
    • These valves have a swinging plug internally and can be opened for maintenance/cleaning
  • Lift / Piston
    • Very low profile valves that have all integral parts.  The spring in this valve re-seats at very low flows/pressures and gives a positive seal.  Piston check valves are typically specified with a cracking pressure number.
  • Wafer
    • Check Valves that are held between two flanges.  Easy maintenance and installation.
