FloSource has recently expanded our stocking program for the Bray Series 30/31. We thought this would be an appropriate time to review this product for our clients. Don’t hesitate to call us for additional information or technical assistance.
Bray Series 3o are the wafer version while the series 31 are the lug version. Both are resilient seated butterfly valves with unique features that make them a cut above the rest. For starters the Bray 31 (LUG) is standard with a Ductile Iron Full Lug Body. This is a much stronger body material than cast iron which is found standard in most butterfly valves. All Iron bodies receive a best in class glossy RED polyester coating that is corrosion and wear resistant.
Bray Series 30/31 valves offer a 1 piece stem which is stronger than 2 piece stems. The unique double D stem to disc design doesn’t utilize taper pins or plugs thus eliminating dis-engagement and loose parts in your pipeline. This design is precision machined and eliminates hysteresis. Along with that the valves don’t utilize a bottom entry plug for a lower stem or bushing. This eliminates a very common leak point for customers.
Bray has standardized on a unique tongue and groove seat design. The tongue and groove design locks the seat in place and allows it to be used in dead end service. Bray also offers the largest seat material selection of any manufacturer, which makes finding a compatible seat material easy.
All these features add up to a valve that is maintenance people truly appreciate. The Bray 30/31 are among the easiest to rebuild and can be done with no special tools or fixtures. A typical rebuild takes around 10 – 15 minutes once out of line.
