EN 593 High-Performance
Butterfly Valve, API 609, 20 Inch/DN500, 150 LB, Double Eccentric.
A double offset butterfly valve is ideal for pipeline isolation and regulation, particularly where frequent open/close operations are needed. Bosseal valves offer several advantages: zero leakage, low torque, long working life, and low emissions. Additionally, they provide bi-directional sealing and are fire-safe, making them highly reliable and efficient for demanding applications.
