Bray Series 30/31 resilient seated butterfly valves provide reliable isolation and flow control for industrial and commercial applications. Available in wafer (Series 30) and lug (Series 31) body configurations, they deliver bidirectional bubble-tight shutoff within their rated operating limits. The high-strength, one-piece stem and internal disc-to-stem connection ensure efficient torque transmission and dependable operation. A tongue-and-groove seat isolates the body and stem from the process media, helping reduce corrosion. The ISO 5211 top mounting flange allows direct mounting of compatible Bray actuators. With a range of body, disc and seat materials available, these valves can be configured for water, wastewater, HVAC and other compatible fluid-handling systems.
