Water & Wastewater
Bray is the leading butterfly valve and actuator manufacturer in water filtration.
Bray International is the world’s premier manufacturer of valve and actuation products for the water/wastewater industry. In most regions of the world, water is a scarce resource and Bray is a leading solution provider of products on a wide variety of treatment systems and installations.
Butterfly, ball, check, knife gate, actuators and control products manufactured by Bray meet the highest industry standards in water and wastewater applications around the globe.
Valves suited for the purpose
Resilient Seated Butterfly Valves
In applications up to 250 psi for valves up to 12 inches and 150 psi for 14 inch and larger.
Temperatures up to 250 degrees F and pipeline velocities at or below 30 feet per second.
High performance valves
Pressure ratings comply with ASME Class 150, 300 and 600.
Temperatures up to 450 degrees F.
Featuring superior materials for erosive and corrosive services including water velocities higher than 30 feet per second.
The strength of Bray valves
Part of the strength of Bray valves is that they offer three disc-to-stem connections; Double ‘D’, Splined, and Double Key. These internal non-wetted connections eliminate typically exposed external disc-to-stem connections such as screws or taper pins. Disassembly of Bray’s internal connection is performed by simply pulling the stem out of the disc. Bray’s precision machining of the disc and the stem connection minimizes hysteresis and produces maximum strength engagements. All stem designs incorporate a blow-out proof feature.
