The Bailey Valve Model B-5 sleeve valve has been designed to incorporate features that provide superior valve performance for inline flow control and pressure reduction applications. Typical applications for the model B-5 are water treatment plant flow control, pump control, tank level control, metering vaults, reservoir discharge and ground water recharge. 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.
