  NSV High Pressure with PSC Swing check valves, like all check valves, are used to which allow fluid to flow in one direction but prevent it from flowing in the other, are available in
a wide range of styles. Swing valves, because of their less controlled opening and closing
mechanics, are used in less sensitive applications.

STRUCTURAL FEATURES

• Advantage&Disadvantage

  The primary benefit of swing check valves is their ability to allow a full, unobstructed flow— which is particularly important in piping systems that may require line cleaning. Swing check valves are also ideal for use in low cost systems with manual valves, such as gate valves in common use.

  Disadvantages include a high rate of wear due to the rotation about the hinge pin and the requirement for full and precise alignment of the disc and seat upon closing. The limitations of this design restrict their use in pulsating systems with intentionally cyclic pressures, as the constant pulsating action of the valve leads to premature wear
