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, ...

An oscillating control valve may appear to be the source of control instability and repair efforts are usually focused only there. When this fails to solve the issue, further investigation often ...

The piSAVE sense is a flow-control/check valve for suction cups. It works in any orientation, is dirt tolerant, and increases vacuum flow through the valve when vacuum level drops to compensate for ...

Equipment designers find that proportional control technology is ideal where precise performance is required in variable pressure or flow applications. Often perceived as more complicated than other ...

studying control valve user requirements for dynamic performance of control valves defining of terms, performance categories, test methods and instrumentation, performance parameters, specification ...

Cavitation is the implosion of tiny vapor bubbles in a liquid when the static pressure reaches the vapor pressure of the specific liquid. This happens when, due to a high pressure differential across ...

Hyundai is recalling 85,043 Sonata sedans whose gas tanks may melt, increasing the risk of a fire. An issue with the purge control check valve can fill the tank with compressed air, leading to ...
