Bray Controls has specifically designed a line of 22in to 96in 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. 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 it is available in valve sizes ranging from 22in to 48in. For larger valves from 52in to 96in, the double keyed disc-to-stem connection offers double keyways machined into the disc, matching double keys in the stem.
