High performance butterfly valves are used for shutoff and throttling control. They are designed to handle everything from general applications to viscous and corrosive liquids; corrosive gases and steam.

A wide variety of seat types are available including:

• PTFE seat  - providing bubble-tight shutoff in both directions),
• Seats for dirty, viscous services
• Fire safe seats - designed for fire safe applications

Soft seats are offered in several materials along with metal seats for the high temperature applications. Stem seal options for fugitive emissions control, pressurized neck extensions for cryogenic applications, plus many other options are available.

High performance butterfly valves come in sizes from 2'' up to 60”, with body materials ranging included carbon steel, stainless steel, duplex stainless steel and other alloys. Their temperature ranges are from -20 to 900F depending on the seat design.

The packing gland is also  included, it would be allows for adjustment of the load to the packing to prevent external leakage. Seat are typically replaceable and the body has a stop to prevent over-travel. The valve stem and valve body are redesign and entrench to meet the require up to class 600 ratings. The connection is included the wafer, flnaged, lugged manual or actuated.

To select the buttefly valve that's right for your application, we need to make sure to take viscosity, temperature, size of bulkal material of the liquid and the application itself into cosideration.
