Crane Center Line® Series RS Butterfly Valves

PRODUCT DESCRIPTION

Center Line® RS resilient seated butterfly valves provide repeatable, vacuum-tight shutoff across abrasive, corrosive applications. The replaceable cartridge seat design with solid backup enables reliable service life in demanding processes.

The RS centerline series RS butterfly valve delivers maximum corrosion resistance by having only two wetted components (disc and seal) and no exposed metal-to-metal contact points. Additional corrosion and abrasion resistance come from a self-centering disc with a wear reducing smooth spherical edge.
