Model B-5 -Bailey Valve

The Bailey model B-5 valve dissipates energy and controls flow by diverting the water path through a perforated movable sleeve. The Valve modulates by sliding the sleeve through a seat ring to expose varying amount of nozzle area.

The sleeve is designed with multiple sized and spaced tapered nozzles for each specific project and possesses a 1:1 stroke to diameter ratio for high turndowns. This design controls cavitations by directing damaging implosions away from any metallic from debris surfaces, thus reducing vibrations and noise normally associated with modulating valves.

The nozzles are placed within the sleeve in a helical pattern that allows for specifically desired incremental volume change with movement of the sleeve. Each sleeve nozzle configuration is designed for the application needs to produce superior flow and pressure control over the entire requested flow range. Flow passes through tapered nozzles in the sleeve and energy is dissipated during a mixing process in the center of the valve.

The advance and retract movement of the sleeve may be accomplished by an operator shaft, hydraulic cylinder, or integral piston located on top of the valve. The Bailey Valve model B-5 is capable of flowing from 20 GPM to 10,600 GPM.
