ASHRAE 90.1 indicates that if this pump is 10 hp or greater, a variable volume pumping solution is required, which would include two position (open/closed) valves at each heat pump and a VSD at the ...

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, ...

Over the past several years, researchers have been developing soft analogues of traditionally rigid robotic components. In fluid-driven robotic systems, pumps control the pressure or flow of the ...

This technology helps block contaminants from entering or leaking out of clean rooms in biotechnology, pharmaceutical, and semiconductor manufacturing settings, preserving the sterile conditions these ...
