In steam boiler applications, pressure relief valves (PRVs) are the silent sentinels — the last line of defense against potentially disastrous overpressure situations. In a perfect world, boiler ...

Learn about the proper location for those valves, managing blowoff steam and turbine exhaust, and more. Very few deaerators utilize vessels that are not constructed and stamped in accordance with ASME ...

Feedwater control valves play a critical role in boiler operation. One important parameter of their design is the pressure drop at the rated condition as well as off-design conditions. However, ...

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 ...
