Features & Benefits
Bray’s Series 3A/3AH resilient seated butterfly valve features a double flanged design that is well-suited for dead-end service. International compatibility is a major design advantage of Bray’s modular valve product lines.
The same valve is compatible with most world flange standards – ASME Class 125/150, BS 10 Tables D and E, BS 4504 NP 10/16, AS 2129 and JIS10. Additionally, Series 3A and 3AH valves are designed to comply with ISO 5752-Table 2 (EN558 Table 13) face-to-face and ISO 5211 actuator mounting flanges resulting in one valve design that can be used in a variety of world markets.
