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 ...

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 ...

Every medical device engineer likely has that one project that's both challenging and interesting enough to stick with them long after it's completed. For John Hayes, director of integrated systems at ...

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 ...

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 ...

• Standard solenoid valves pose an ignition danger near hazardous materials. • Valves with pneumatic and magnetic actuators require no electricity, making them inherently safe in hazardous locations.
