What is Triple Eccentric Butterfly Valve ?
Triple Eccentric Butterfly Valve is a premier valve well-suited for operation in light vacuum to high-pressure applications and ideally suited for applications requiring absolute zero leakage. Compared to gate, globe or ball valves of the same size and pressure class,
Triple Eccentric Butterfly Valve provides space and weight savings while minimizing installation and maintenance costs.
