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, ...

Setting up a pressure control process involves choosing between absolute pressure and gauge pressure. For a number of applications the choice could be to stick to an established convention, however ...

The hypertensive and normotensive Appropriate Blood Pressure Control in Diabetes (ABCD) studies were prospective, randomized, interventional clinical trials with 5 ...

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 ...

Pneumatic furnace damper drives may be more common, but electro-hydraulic actuators provide several advantages to the more traditional control scheme. One fossil-fired plant in Taiwan achieved more ...
