Explore this product family →How to navigate the range
Choose by service risk and wetted construction
Start with the fluid, pressure and temperature, then narrow the valve construction, wetted materials, connection and actuation.
Aluminum centerline butterfly valves
Start here for compatible water, HVAC and equipment duties where a lighter valve body is useful.
High-performance butterfly valves
Start here when the project calls for Class 150/300 offset soft-seat or metal-seat configurations.
PFA-lined valve families
Start here when media compatibility makes a fluoropolymer-lined wetted path a candidate for review.
Ductile iron and stainless references
Start here when a project specification requests traditional ductile-iron construction or selected stainless pressure-boundary and trim materials.
Butterfly-valve architecture
Compare construction before selecting a model
Aluminum remains the flagship; offset, lined and ductile-iron routes extend the project selection.
