DeZURIK Butterfly Valves

A butterfly valve is a quarter-turn valve with a rotating disc element that allows, controls, and obstructs the fluid flow in a pipeline. These simple, compact valves induce a low pressure drop across the valve.

Where Are Butterfly Valves Used?

A butterfly valve is used to regulate the flow of materials within large pipe diameters. These versatile valves are designed for shutoff of clean and dirty water and gases. They are commonly specified because they allow for quick shutoff and typically cost less than other valve types.

DeZURIK Butterfly Valves

The DeZURIK butterfly valve catalogue includes a number of municipal and industrial butterfly valve styles to handle different applications. There are numerous types of Butterfly valves - from AWWA, Double Off-set, Triple Off-set, High performance, Uninterruped or On-Center Resilient Seated - to completely customized options.

AWWA Butterfly Valves

AWWA Butterfly Valves, designed to meet stringent American Water Works Association C504 and C516 standards, are used for shutoff on clean water and gases. They are a resilient seated butterfly valve, available in sizes from 3-144", with temperature ranges to 290 degrees Fahrenheit.

High Performance Butterfly Valves

High Performance Butterfly Valves are designed for extreme services, including high-temperature services, throttling steam control, high-cycle industrial gas, and more. These ASME Class 150 or 300 valves are available in sizes up to 60”, and can handle temperatures up to 700°F.

Uninterrupted Seat Resilient Seated Butterfly Valves

Uninterrupted Seat Resilient-Seated Butterfly Valves are used to handle a wide variety of liquids and gasses. They provide bi-directional shutoff to the full rating of the valve and can be used in dead-end service without requiring downstream flanges. The Uninterrupted Seat Butterfly Valve is an excellent choice for continuous modulating control, or for extended service applications such as high cycle and higher pressures. Available in sizes 2-42”, with temperature ranges to 250°F.

On-Center Resilient Seated Butterfly Valves

On-Center Resilient Seated Butterfly Valves are used in general service applications for a wide variety of liquids and gases. They provide bi-directional shutoff to the full rating of the valve and can be used on dead end service with downstream flange attached. The On-Center Resilient Seated Butterfly Valve can handle pressures up to 175 psi in 2-12” sizes and up to 150 psi in 14-48” sizes.

BTG Tail Gas High Performance Butterfly Valves

Tail Gas High Performance Butterfly Valves are used for tail gas service in refinery sulfur recovery units, polymer processing or adhesive manufacturing. They are designed to meet the rigorous requirements of services where polymerization or solidification of media can prevent valves from operating.
