Colton Industries develops high performance butterfly valves that feature a carbon steel wafer/lug body or stainless steel wafer/lug body. Both butterfly valve types are available in 2-1/2" to 12" sizes with bodies designed to fit between ANSI 150 flanges. All valve sizes are available with a multi-position latching or a wheel-handled gear operator. The carbon steel valves feature a maximum operating pressure of 285psi, while the stainless steel valves have maximum operating pressure of 275 psi.

Cameron provides WKM-brand triple offset butterfly valves used for liquid pipelines. The valves eliminate friction at the sealing surfaces; and feature a disc and seat surface that meet at a chosen contact angle for frictionless compression. The seat contour of the valves ensures compressive sealing around the entire seal ring.

Erdmann Corporation distributes high performance butterfly valves manufactured by Xomox.The valves feature positive bi-directional flow, along with a double offset and eccentrically-mounted disc. Available valve configurations include: cyrogenic, enhanced fugitive emissions control, extended packing, fire-tested, high temperature, jacketed, rail tank car valve, steam trace, and wafer and lug styles.

Valtorc designs and manufactures double eccentric, high performance butterfly valves; double offset, high performance butterfly valves; and triple offset, metal-seated butterfly valve. The triple offset valves are for cryogenic and high temperature applications, and features zero leakage, tight shutoff, and low friction and torque. The double offset valves are rated to full 285 psi pressure, with a pressure/temperature rating of ANSI B16.34. The double eccentric valves conform to full ASME Class 150 and 300 ratings, and feature a one-piece wafer body style or full lug-style for dead end service.

ABZ Valves & Control manufactures high performance butterfly valves available in 2" to 72" and 2" to 24" sizes. Featuring double or triple offset design, the valves have either wafer, lugged, double flanged, or butt-welded connections - with rating of ANSI 150/300/600. Other valve features include: a free floating seat design and direct mount operation.

Butterfly Valves & Controls Inc. produces triple eccentric butterfly valves in sizes 3" through 24". Available in triple eccentric, wafer, lug, gate valve, and face to face styles, the valves feature working pressures of ANSI 150, ANSI 300, and ANSI 600. Additionally the butterfly valves feature a cast carbon steel or stainless steel body.

Shipham Valves designs and manufactures high performance, double offset butterfly valves in 2" to 24" sizes. Featuring double flanged or wafer lugged end connections, the valves are resilient seated and feature pressure class 150 or 300.
