The Series 30/31 is engineered to provide bidirectional bubble-tight
shutoff and isolation of the line media from the stem or valve body.
Available
with a wide selection of high-quality resilient seat & disc
materials for a variety of applications, our Series 30/31 butterfly
valves are easily automated for on-off or modulating service.
The Bray Series 32/33 Resilient Seated Butterfly Valve has many of the design features and benefits of the smaller Bray valves, such as high Cv ratings, minimum parts exposed to the line media, greater reliability and a proven record of long service life.
The Series 20/21 resilient seated butterfly valve surpasses the high standards required in sanitary valve applications, and inherent flow characteristics and capabilities. Bray's Series 20 valve is a wafer version with flange locating holes, and the Series 21 is the companion lug version for dead-end service and other flange requirements.
