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.

An economical way to reduce control valve or reducing valve noise by 6 to 12 dBA is to install the Les-Sonic Silencing Orifice downstream from the valve between two flanges. Learn More

Leslie Eventemp temperature regulators use a self-contained, liquid-filled thermal system that is completely independent of external power sources such as air or electricity. They use only the flowing medium as the means to operate, resulting in lower initial cost and lower operating cost All Leslie Eventemp regulators are available with an optional calibrated dial (in your choice of °F or °C) for quick, easy and dependable temperature settings. The dial eliminates waiting for equipment to heat up before the proper setting can be determined and avoids overheating due to Òguess" setting. It is suited for production line use where frequent readjustments are necessary for process work. The calibrated dial replaces the standard adjusting sleeve. Learn More

The Leslie GPS Series features multiple different GPS regulator options along with a VPS external pilot option. The pilots have inter-changeable springs for 3-20, 5-50, 10-100 and 20-150 Psig pressure ranges. Learn More

Leslie Class VKP steam pressure reducing valves use an adjustable, spring-controlled integral pilot valve to establish a pressure feedback loop which controls the main valve. This entirely mechanical principle tends to keep systems in equilibrium within 90 percent of the set point. Learn More

The Leslie Class DOT cage throttling, 3-Way control valves provide easy maintenance and increase valve stability and trim life. Spring loaded Teflon® chevron stem packing eliminates the need for periodic adjustment. The DOT features a one-piece body eliminating the conventional tail piece and extra gasketed joint. Common applications include the circulation of water, oil, sea water, or other liquids in heating/cooling systems where there is a heat exchanger bypass control. They can also be used in blending systems and on/off selector systems. Learn More
