In the early 1980’s Kennedy recognized and increased the requirements and escalating maintenance cost of water systems in the United States. Kennedy responded by introducing the first RW (resilient wedge) Valve in America. This introduction revolutionized the valve market in the U.S. Kennedy was the first to introduce, and still leads in, the design and technical development of the bubble tight resilient seating valve. The RW Valve, with its unique features and benefits, is the first to be manufactured with both AWWA and UL/FM approval for all water system requirements.

• The valves shall have a ductile iron body, and bonnet
• The wedge shall be completely encapsulated with EPDM rubber
• The sealing rubber shall be permanently bonded to the wedge to meet ASTM tests for rubber metal bond ASTM D249
• Valves shall be supplied with O-Ring seals at all joints (no gaskets are used in the valve design)
• The valves shall be either non-rising or rising stem, opening by turning (left or right) and provided with 2 IN square operating nut or a handwheel with the “Open” and an arrow cast in the metal to indicate the direction to open.
• NRS stems shall have (2) O-rings located above thrust collar and (1) O-ring below
• The NRS stems shall also have (2) low torque thrust bearings located above and below stem collar to reduce friction during operation
• Waterway shall be smooth, unobstructed and free of pockets, cavities, and depressions in the seat area, valves shall be able to accept a full size tapping cutter
• The body, bonnet, and stuffing plate shall be coated with fusion bonded epoxy, both interior and exterior on body and bonnet
• Epoxy shall be applies in accordance with AWWA C550 and be NSF61 and NSF372 certified
• Each valve shall have a maker’s name, pressure rating, and year in which it was manufactured cast in the body
• Prior to shipment from the factory, each valve shall be tested by hydrostatic pressure equal to requirements of both AWWA and UL/FM
• All internal parts shall be accessible without removing the body from the line
• Valves shall have all brass components cast and assembled in the USA
