Basic PSA


PSA Mechanical Shock Arrestor (Snubber)The PSA Mechanical Shock Arrestor (Snubber) was designed to protect piping systems and other associated components such as valves, pumps, and steam generators from abnormal movement resulting from water hammer, plant transients, earthquakes, etc.

The PSA Mechanical Snubber controls unwanted movement by becoming a load carrying member between the piping and structure the instant a force sufficient to cause abnormal movement is initiated. The potentially damaging motion is arrested before it has a chance to develop. However, for normal thermal motion movement, the PSA Mechanical Snubber telescopes freely in either direction through its full operating stroke.
