Quadrant is a Louisiana-based manufacturer of ball & butterfly valves and actuators to operate these products. Located in Broussard, Louisiana (a suburb of Lafayette), they operate from a 22,000 square foot facility which houses manufacturing, engineering, sales & marketing and all support services.

As an extension of the seal-welded designs, Quadrant has developed the ONLY full line of ASME B16.34 AND API 608 compliant ball valves in Class 900, 1500, 2500, and 4500 (the highest ASME B16.34 pressure class). These products allow users to fully comply with the ASME Piping Code, which require the use of compliant valves in affected facilities.

In Flanged-End Ball Valves, Quadrant excels. The valves are available in a Unibody or 2-piece design, in sizes from 1/2" to 10" and classes from ASME 150 to 600. Every flanged valve is Fire Safe (API 607 5th), NACE Compliant and ASME B16.34/API 608 Compliant. These valves are designed with a "modified square" stem and submerged stem packing to provide direct mounting of ISO 5211 Compliant actuators and gear operators with no interface hardware.

Butterfly Valves in three separate product lines help to flesh out Quadrant's offerings. Available in sizes from 2" through 48" and in wafer and lug styles, these butterfly valves are in compliance with both NACE and API 609 standards, have a Category A Certification from the US Coast Guard, and offer a patented ISO5211 top works to allow direct mounting of actuators and operators with no interface hardware.

In 2007, Quadrant expects to unveil a new High-Performance Butterfly Valve to allow for high pressure dead-end service as well as other unique applications.
