AWWA C50909 ResilientSeated Gate Valves for Water Supply

AWWA C50909 ResilientSeated Gate Valves for Water Supply Service This standard describes ironbody, resilientseated gate valves with nonrising stems (NRS) and outside screwandyoke (OSamp;Y) rising stems, including tapping gate valves, for water supply service having a

What is the difference between AWWA C509 and AWWA C515

AWWA C509 standard was developed in 1980 to formalize the design standard for resilient seat valves for water and waste water. The wall thickness was adopted from the standard first published in 1952 for metal seated valves AWWA C500.

MODEL 2639 AWWA C509 FULL BODY DUCTILE IRON

Valves shall conform to the latest revision of AWWA Standard C509 covering resilient wedge gate valves. The valves shall be either, nonrising stem or rising stem, opening by turning stem left or rightand provided with 2 square operating nut or handwheelwith the word Open and an Arrow cast in the metal to indicate direction to open.

Resilient Wedge Gate Valves Kennedy Valve Co.

Oamp;M Manual Resilient Seated Gate Valve C509 2quot; 12quot; During the decade of the 1980s, the waterworks industry was introduced to the Resilient Seated Gate Valve, a design principle that is dominant in preference for use in distribution systems.

NRS Gate Valve AWWA C509/C515 Resilient Seat United

Resilient Seated gate valves were first covered by AWWA Standard C509 in 1985. The predominant metal used to cast valves at that time was Gray Cast Iron. Therefore the Standard was written around this gray cast iron material, which has a tensile strength of 31,000 psi, no yield strength whatsoever, and no capability for elongation.

Resilient Wedge Gate Valves Clow Valve

C509 2quot; 12quot; The Clow Resilient Wedge Valve, with its unique features and benefits, was the first to be manufactured with both AWWA and UL/FM approval for all water system requirements. Clow Valve Co was the first to introduce, and still leads in the design and technical development, of the bubbletight resilient seating valve.
