New research may take the current 'gold standard' for heart valves to a new level of reliability. A team of researchers has developed a way to improve overall blood flow through the valves, so the ...

Half-Life 3 may not be here yet, or ever arrive, for that matter, but that doesn’t mean there aren’t already plenty of ...

Turbine bypass valves are one of the most difficult applications in a power plant. Keeping these valves operating efficiently and avoiding unexpected failures is critical for plant operation. When ...

Scaling is one of the most frequently occurring problems in geothermal power plants and can prohibit the control of well flow if it builds in the well or wellhead. At HS Energy on the Reykjanes ...

Following last week's report Valve is working on a new iteration of its brilliant (if divisive) Steam Controller, a fresh leak has offered what might well be a first look at its refreshed design - and ...

New ZL Series proportional flow control valves from HydraForce Inc. (Lincolnshire, IL) are internally pressure-compensated and operate in two directions. "The valves provide identical flow vs current ...

Fluid-handling devices are not basically concerned with the modulation of power, but only with the movement of fluid. Choosing a fluid-handling valve used to be easy, because each one had its own area ...

• The first step in selecting a valve is determining its function. • Review Cv or pressure drop when considering one valve versus another. • Don’t overlook maintenance requirements when specifying a ...
