Assured Automation introduces the HP Series of high-performance butterfly valves. They offer Class VI shutoff and an advanced seat design, which provides a bi-directional interference and pressure-assisted seal. These valves are available in two- through 12-inch sizes (5.08 through 5.08 cm) with a pressure rating up to 285 psi for 150 class and 740 psi for 300 class valves. The body is available in carbon or stainless steel with wafer or lugged flanged-end connections. The HP Series disc is engineered for a quick release from the seat, which reduces torque and seat wear. Machined position stops on the body locate the disc in the seat to achieve maximum seat and seal life. A full range of accessory items are available, including limit switches, solenoid valves, positioners and manual override devices. http://assuredautomation.com, kimo@aa-fs.com
