Conval (Somers, CT) now offers Swivldisc® Gate Valves in 1/2- through 4-inch sizes. The Swivldisc features a superior wedge gate design that employs a flexible disc, explains the company. This disc permits the seating surface to achieve perfect alignment and establishes a tight seal that is not possible with standard wedge gates. Swivldisc Gate Valves are available in ASME / ANSI Pressure Classes through #4500. Standard materials of construction are Carbon Steel 216 GR WCB, Chromalloy SA-217 GR WC9, SA-217 GR C12A, and SA-351 CF3M. Other materials are available upon request. Options include bypass, air, or motor actuators.
