Model B-14 (Open Discharge 8 - 72") - Inline Configuration |

  Introduction: The Bailey Valve model B-14 sleeve valve has been designed to incorporate features that provide superior valve performance for atmospheric or submerged discharge in flow control and pressure reduction applications. Typical applications for the model B-14 are turbine bypass, reservoir discharge and ground water recharge. The Bailey model B-14 valve dissipates energy and controls flow by diverting the water through multiple orifices located within the sleeve and discharging to atmosphere or body of water. The valve modulates flow by sliding an outer pipe called the gate over an inner pipe called the sleeve. The sleeve is designed with multiple sized and spaced tapered nozzles for each specific project. This design controls cavitation by directing damaging implosions away from any metallic surfaces, thus reducing vibration 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 gate. 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 from the inside of the valve out through tapered nozzles in the sleeve and energy is dissipated outside of the valve body. The advance and retract movement of the gate is accomplished through two (2) drive screws or hydraulic cylinders located on each side of the valve. The Bailey Valve model B-14 is capable of flowing from 500 GPM to over 443,939 GPM. Standard Materials: Inlet Body: Epoxy Coated Carbon Steel Outlet Body: 304 or 316 Stainless Steel Gate: Stellite Hardfaced 304 or 316 Stainless Steel Seat Ring: 304 or 316 Stainless Steel Seals: Buna-N Pressure Class: ANSI B16.5 Class 150 => 250 PSI Class 300 => 640 PSI Class 600 => 1000 PSI Size Range: 8” (200mm) through 72” (1830mm) Product Category: Inline – Straight w/ open discharge or submerged discharge Features: - Offer 1:1 Stroke to Diameter Ratio
- Provides better flow control over short stroke configuration by increasing the sleeve nozzle spacing
- Reduces the risk of oscillating the gate on the seat under low flow and high delta P condition
- Allows for more cavitation dissipation compared to shorter stroke valves
- Reduces vibration by spreading discharge energy over broader range compared to shorter stroke valves
- High flow turndown allows the use of one valve in lieu of multiple parallel valves and eliminates oscillation off the seat for most applications
- Stellite Hardfaced Gate
- Provides superior hard surface edge to reduce high velocity erosion of the gate
- Creates dissimilar hardness in non-bound mating materials
- Provides gate leading edge hardness sufficient to shear debris within the nozzle
