Valves are designed, manufactured, and tested in accordance with AWWA C508. ANSI B16.1 Class 125 Flanges. Working temperature is 14°F to 248°F.

F B E C :F B E C :

J&S Valve’s check valve is provided with fusion bonded epoxy coating inside and out. FBE coating is NSF61 approved for potable water and in compliance with AWWA C550. Fusion Bonded Epoxy is a one-part, heat cured, thermosetting epoxy coating that is applied as a dry powder to the sand-blasted surface of a pre-heated valve and then fused and cured in a high- temperature oven. The result is a durable coating with exceptional abrasion and chemical resistance making it ideally suited for valves in water and wastewater applications.

D I C :D I C :

J&S Valve provides standard swing check valves with ductile iron construction rated to 250 psig. Cold Working Pressure (CWP). Ductile iron provides a greater strength and toughness than conven-tional gray iron materials. With ductile iron construction, the body, disc, and disc arm can safely with-stand high stresses and shock loads.

C R :C R :

The body and disc are fully encapsulated with NSF/ANSI 61 certified fusion bonded epoxy per AW-WA C550 to prevent corrosion and provide an extended service life. The shaft, disc pins, and seat hardware are constructed of 300 series stainless steel for the maximum corrosion resistance in se-vere service. Lead-Free Bronze bushings are provided in the body to provide smooth and reliable disc closure.

L S :L S :

In addition to the many features and characteristics of the swing check valve, an optional SCADA compatible limit switch can be utilized for remote panel read outs and/or secondary system opera-tions indicating the open or fully closed position of the valve.
