resilient seated butterfly valve is a Double Flanged design which can be used for dead-end service. A major design advantage of product lines is international compatibility. 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, DIN ND 10/16, AS 2129 and JIS10. In addition, the valves are designed to comply with ISO 5752-Table 2 (EN558 Table 13) face-to-face and ISO 5211 actuator mounting flanges. Therefore, one valve design can be used in many different world markets.
