Common Causes of Swing Check Valve Failure and How to Diagnose and Resolve Them
Posted by Jeff Kane on
Swing check valves use a hinged swinging disc to block and control the movement of fluid in a system. As they are used to prevent the reverse flow of fluids or gases, any failure can lead to leakage, loss of pressure, contamination, overflow, and, in the most severe cases, complete system failure. Below we discuss… Read More
Why Do DFT® Axial Flow Check Valves Inherently Reduce Water Hammer?
Posted by Jeff Kane on
Hydraulic shock—more commonly known as “water hammer”—occurs when the flow within a pipe is suddenly forced to change direction, which creates a pressure wave that can be characterized by a loud knocking or banging sound. In piping and process systems, water hammer often happens upon closing a valve to stop or redirect flow. It’s important… Read More
