Check valves are installed in many piping systems. Their purpose is to allow flow in only one direction, which can be critical for plant safety and to protect equipment from damage. There are a few ...

Directional-control valves are common in pneumatic systems. They control compressed-air flow to cylinders, rotary actuators, grippers, and other mechanisms in packaging, handling, assembly, and ...

Flow reversal in piping systems can degrade equipment performance and cause significant water hammer, potentially resulting in catastrophic failure. Power plant condenser cooling water systems—or ...
