Fluid Power:Bray Controls has designed a line of 22 to 96 inch (550 to 2,400 mm) resilient, seated butterfly valves for highly abrasive and corrosive applications. These valves meet process requirements with chloride content from low to very high parts per million in applications such as seawater, mining, sanitary service and FGD at an economical price.
The internal disc-to-stem connections prevent many valve failures due to erosion, corrosion and vibration. The splined disc-to-stem connection features matched, precision machined male splines in the stem and female in the disc, and is available in valve sizes ranging from 22 to 48 inch (550 to 1,200 mm). For larger valves from 52 to 96 inch (1,300 to 2,400 mm), the double keyed disc-to-stem connection offers double keyways machined into the disc, matching double keys in the stem.
