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. Das Medium kann praktisch ungehinderte durch die Armatur strömen und ermöglicht schon bei einem niedrigem Differenzdruck eine komplette Öffnung der Scheibe. Rite Sized, combined with the limited movement of internal parts during operation, reduces wear – enhancing the long service life of a Bray/Rite® valve.
