Variable valve timing and variable valve lift may sound similar, but they're entirely different. Here are the differences between them and how they work.

LONG BEACH, Calif. - Pumps are responsible for a significant part of the world’s electrical energy consumption, but their impact can be by using variable-speed pump control, especially in hydronic ...

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, ...

Control valves experience significant reaction loads when they regulate choked flow. The highly restrictive, complex flow path of existing severe-service valves dissipates the forces from ...
