    Limitorque Actuation Systems A profile of the company that’s intelligently automating the world’s valves Making valve control eas for customers When the gates of a huge hydroelectric dam open and allow millions of gallons of water to around the surge through, there’s a hidden force that moves them. When oil pipelines stretch over hundreds of miles of frozen tundra or across furnace-like wor desert sands, there’s a control mechanism that automates the flow no matter how hostile the environment. When a nuclear-powered super carrier puts to sea, it becomes a floating city supported by a network of pipes and valves delivering everything from the steam that powers the propellers to water for the kitchen sink. The complex engineering behind each of these systems depends on the precise, reliable operation of a relatively simple mechanism: a valve. For well over half a century, valves in applications from the extraordinary to the everyday have depended on valve actuators from a company called Limitorque. 2 A heritage of innovation that spans more than seven decades. Limitorque is an operating unit of Limitorque’s original torque-limiting Flowserve, a $2.5+ billion-a-year innovation was devised, company strongly focused on then was adopted by essentially all automation.

  • Fluid Ow in a Rotating Low-Specific-Speed Centrifugal
    Fluid Dynamics Research 24 (1999) 275–292 Fluid ow in a rotating low-speciÿc-speed centrifugal impeller passage F.C. Visser ∗, J.J.H. Brouwers 1, J.B. Jonker Faculty of Mechanical Engineering, University of Twente, Enschede, The Netherlands Received 17 December 1997; revised 25 June 1998; accepted 4 July 1998 Abstract Results from experimental investigations of the blade passage ow in a model pump impeller of low speciÿc speed are described. It is found that the ow inside the rotating impeller passages is well described by the ow distribution postulated by potential- ow arguments and boundary-layer considerations. Using a custom-designed two-component laser-Doppler- velocimetry ow measurement system, mounted on a frame co-rotating with an impeller, the radial and circumferential velocity components of the relative ow inside an impeller passage were measured. Measurements were taken from blade to blade, and from this the passagewise uid velocity was determined. The measured passagewise uid velocity is compared to the potential- ow solution of the impeller passage- ow velocity that holds asymptotically in a region well away from the blade tips. Additional potential- ow ÿnite-element calculations are used for comparison for those regions where the asymptotic expansion does not hold. The agreement between the experimental and theoretical values is seen to be good for the core ow region, which extends from the blade pressure side to the viscous boundary layer at the blade suction side. Furthermore, the calculation of the boundary-layer development along the suction side of the impeller blades is highlighted. Contrary to the blade pressure side, only there a signiÿcant departure from inviscid ow behaviour is observed.
