Resilient Seated Butterfly Valves
Wed, 09/05/2007 - 8:26am
The ST Series of wafer and lug-style resilient seated butterfly valves offer high Cv (flow coefficients), ISO top mounting, one-piece body with self-centering disc, and a large selection of direct-mount actuators and gear operators. Although they feature direct-mount actuators, they are also available as manual valves with limit switches for those applications that do not require automation but do require feedback to a PLC or network bus system. The valves are available in sizes from 2 through 12 in. with a pressure rating up to 225 psi and from 14 through 24 in. with a pressure rating up to 160 psi. They feature a one-piece, ductile iron body and a fusion-bonded epoxy body coating for corrosion resistance. No gasket is required for mounting between flanges, and additional gaskets or O-rings are not needed for installation. Buna-N or EPDM seats are available; a 316 stainless steel disc is standard while bronze and ductile iron discs are also available.
