An axial flow silent check valve’s disc is held in place by a spring. This upgraded structure design brings about many advantages. First, as its name indicates, the streamlined axial flow path through full-port expanded body prevent turbulence, erosion and vibration, which eliminate the process downtime and maintenance cost. Second, the full port passage and high-pressure recovery of the venturi-s...

For high-pressure piping systems where multiple pumps are used together, the problem of water hammer in the piping system is even more acute. Water hammer is a pressure wave of the ever-changing flow in a pressure pipe, which is a hydraulic shock caused by a pressure rise or fall due to the change in the fluid flow rate in the pressure pipe. Water hammer is the combined result of the inc...

Selecting the correct check valve size is more than matching the valve bore to the pipeline diameter. Check valve sizing directly affects flow stability, pressure loss, service life, and protection against reverse flow. An oversized valve may never reach full opening, causing disc flutter and premature wear, while an undersized valve can introduce excessive pressure drop and limit system capacity....
