4 909-953-001 BUTTERFLY VALVE

Suitable for chemical, food or sanitary applications, ABZ™ 909/919 resilient-seated butterfly valves feature a thin profile that maximizes open fluid flow. As with all of our valves, we manufacture the 909/919 series for optimal sealing that protects every valve component. As an example, our unique double-V stem self-seals to protect the stem's top bushing in vacuum pressurized services. In addition, the ring seal is molded as part of the seat to create a positive secondary seal that prevents both leakage into the stem journal and media migration behind the seat.
