High Performance Butterfly Valves comply with API 609 Category B and can be used for shutoff and throttling
control. They are designed to handle everything from general applications to viscous and corrosive liquids;
corrosive gases and steam. Our high performance butterfly valves are a standard in many industries including
heating, ventilating and air conditioning, power generation, hydrocarbon processing, water and waste water
treatment, and marine and commercial shipbuilding. A wide variety of seat types are available including the
dynamic PTFE seat which provides bubble-tight shutoff in both directions; dual metal/PTFE seat for dirty,
viscous services; and the Fire Block seat, designed for fire safe applications, which meets API607 fire test
standards.
