Throttle devices with suitable differential pressure transducers are used for flow measurements of liquids, gases and vapours in pure phase in pipelines. Since transducers have no movable parts and require hardly any maintenance, this reliable procedure is used preferably in chemical and technical processes. What Valves Can Be Used For Throttling? - XHVAL Valve The Throttling Mechanism. When the pipeline use throttling valve, the media flow rate changes. When partially opening or closing the valve, there is a restriction in the flow of fluid. Thus, the control of media. This, in turn, compacts the media in that partially opened valve. Molecules of the media begin to rub to each other. This creates throttling device restriction orifice US5327941A - Cascade orificial resistive device - Google Patents A cascade orificial resistive device for throttling fluid flow which minies acoustic noise and internal vibrations is described herein. The device has a hollow body defining a fluid passageway, a plurality of perforated plates mounted within the passageway, a fixed end ring adjacent one end of the perforated plates, and a threadable end ring adjacent an opposite end of the perforated plates to throttling device restriction orifice

Theory, and Sizing of Air Valves - Val-Matic Valve

Throttling Device Air/Vacuum Valve Air Release Valve SlowClosing Device Air Release Valve AIR RELEASE VALVES Air Release Valves are probably the best known air valve and are typically furnished in sizes in. (13 mm) through 3 in. (76 mm). The valve has a small precision orifice The Limits of Standard Manual Globe Valves for Throttling They run from highly recommending the use of globe valves as a throttling device to measured caution. The best guideline for manual valve selection is API RP 615. Section 5.3 of that standard promotes the use of globe valves as a control device but section 5.3.3 outlines some of the problems that can occur when a globe valve is improperly throttling device restriction orifice The Limits of Standard Manual Globe Valves for Throttling They run from highly recommending the use of globe valves as a throttling device to measured caution.

CN201513631U - Adjustable restriction orifice - Google Patents

The utility model discloses an adjustable restriction orifice. Throttling discs are arranged in counter bores of two clamping flanges, through-holes are formed on the throttling discs and two clamping flanges, when mounting on a fluid pipeline, and the through-holes on the throttling discs and two clamping flanges and holes of the fluid pipeline are mutually eccentric. Ashcroft Accessories - Pressure Dampening Devices device reduces pressure impact, slows the speed and range of pointer movement, and prolongs gauge life. Throttling effect is obtained by installing a restricting orifice between the gauge socket connection and the Bourdon tube.
