Bray/Rite Sized Design Minimizes Wear and Enhances Service Life

Bray Rite Bray Rite -2

Ideal for Control Valves and Low-Pressure Systems

Enhanced Service Life with Shape-Optimized Check Valves

Bray/Rite wafer combination swing check valves are flow activated, and Rite Sized. Bray/Rite inlet ports and disc have been shape optimized to achieve a fully open position at low flow rates (3 ft/s on average). Therefore, the Bray/Rite operates exceptionally well in the flow rates typically found in pipelines containing control valves and lines with varying media flows.Compare the Bray/Rite to typical full-sized swing check valves-- Due in part to their oversized, heavier discs, these valves only fully open at an average flow rate of 11 ft/s. When activated at a lower flow rate, these valves loose true controllability and do not fully open. A partially open disc creates an obstruction that produces a higher pressure drop and fluttering of the valve disc - disturbing the flow and increasing the chance of water hammer.Bray/Rite is Rite Sized to eliminate these problems. 它经过精心设计,可加速通过阀门的管路介质,在低压下实现几乎畅通无阻的完全打开状态。Rite尺寸,加上运行时内部部件的有限移动,能够减少磨损,延长Bray/Rite阀门的使用寿命。
