Bray/Rite

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. Il a été conçu pour accélérer l'écoulement de fluide à travers la vanne et atteindre une ouverture totale presque entièrement dégagée à faible pression. Rite Sized, combined with the limited movement of internal parts during operation, reduces wear – enhancing the long service life of a Bray/Rite® valve.
