Leslie Controls Synflow Sweep Angle Valves for Synfuel Service
Hot separator letdown
Well choke production
Slurry letdown service is the most critical of these applications, involving three-phase flow of solids, liquids and gases at extremely high temperatures and pressure drops that can destroy a conventional valve in a matter of hours.The Synflow Valve has been used successfully in a number of synfuel pilot plant situations where its actual service life has exceeded that of other valves by several orders of magnitude.
Critical body passages of the Synflow are designed to keep wear to a minimum. Plugs and seats are a special tungsten-carbide alloy for corrosion and abrasion resistance. To facilitate maintenance and inspection, all internal parts (except the seat ring) are easily removable from the top of the valve. In the bonnet closure, all boltings and gaskets are designed to eliminate problems inherent in thermal transients.
