Leslie Controls, a manufacturer of valves for the power generation, industrial, marine and oil and gas markets, offers Aeroflow High Performance Control Valves. The Aeroflow line integrates aerodynamic/hydrodynamic flow design, smart valve technology, and a modular design concept to deliver an accurate and reliable valve.
Aeroflow’s aerodynamic flow control valves provide Cv/size ratios while reducing flow turbulence and valve generated noise. As a smart valve, Aeroflow features optional dead zone inlet/outlet for accurate and stable pressure measurements. It also feature digital positioning.
Aeroflow valves exceed ANSI Class VI shutoff, and its pressure energized pilot balanced plug provides zero cc/min leak rates to prevent seat erosion and wire drawing. The pilot design eliminates the need for any piston seals.
