Description

Resilient Seated Butterfly Valve – Series 30/31 (Bray), Wafer & Lug Style, Actuator-Ready

The Bray Series 30 and 31 Resilient Seated Butterfly Valves provide high-performance flow control in both manual and automated systems. Designed for dependability and ease of installation, Series 30 (wafer) and Series 31 (lug) models feature a robust epoxy-coated ductile iron body with concentric disc and resilient seat for bubble-tight shutoff in both directions.

Engineered with an ISO 5211 actuator mounting pad, these valves accommodate direct mounting of Bray pneumatic or electric actuators, enhancing automation efficiency. The high-strength stem design, blowout-proof shaft, and replaceable seat and bushings contribute to extended service life and low maintenance.

With full compliance to industry flange standards and a wide range of disc and seat materials, Series 30/31 valves are ideal for HVAC, water treatment, fire protection, and process piping systems requiring precise shutoff and throttling performance.
