VALVES & ACCESSORIES &Awg <br />SERIES 7800 <br />Check Valves <br />For use In Grooved End Piping Systems <br />The GruvlokSeries 7800 Check Valve Is a compact oast effective valve <br />offering low pressure -drop, non -slam performance. The Series7800 Check <br />Valve assembly Is Iiighterand faster to Install, and oasts less than Flanged and <br />wafer valve assemblies <br />In the fully open position the Series7800 swing clapper Is held tightly against <br />the valve body, out of the Flow stream, to provide maximum Flow area and <br />prevention of clapper Flutter The clapper design produces quick, non -slam <br />closure before Flow reversal an occur, while meeting FM requirements for an <br />anti -water hammer valve rating. <br />Each valve Is hydrostatically tested for leak tightness to 500 PSI. The clapper - <br />seat design permits leak free sealing of back pressures in service conditions <br />ranging from 300 PSI (207 bar) to as low as PSI (0.07 bar) (head pressure'. 28'). <br />PERFORMANCE: <br />Pressure Rating: <br />Commercial Applications -Shes2" flffim 12Inclusive 300 psi (207 bar) <br />maximum working pressure <br />=• O <br />•rmoveo <br />�IAL SMICAT <br />BODY, Duane Iron conform ing toASFM A 536, Grade 65-45-12 <br />COATING: Rust Inhibiting paint on exterior and Interior— color'. orange enamel <br />Body <br />CLAPPER 2"-5"Type304 or 302 stainless steel to ASFM A167 <br />6"-12" Ductile Iron conforming toASFM A 536, Grade 65-45-12 <br />CLAPPER FACING: <br />Spring <br />Clapper <br />❑ Grade EEPDM:-40'to23o'F(-40'to 110'C) Service Temperature Range <br />Assembly <br />Recommended for water service, dilute acids, alkaline, oil -free air and <br />Bushings(2) <br />many chemical services. <br />NOT FOR USE IN PETROLEUM SERVICES. <br />Hinge Pin <br />❑ GadeTNimle:-29to189F(-2Y to 8o'C) Service Temperature Range <br />Recommended for petroleum products, air wlffi oil vapors, vegetable <br />/� <br />oils and mineral oils <br />Hinge Pin Plug (2) <br />Drain <br />NOT FOR USE IN HOT wATERSERVICES. <br />Connections <br />SEAT RING: Type 304 stainless steel ASFM A 173, ASFM A 213, <br />ASFM A 312 or ASFM A 269 <br />SPRING: Type 302 stainless steel to ASFM A313 <br />Seat Ring <br />HINGE PIN: Type 304 or 302 stainless steel to ASFM A 580 <br />HINGE HN BUSHINGS: Slntered bronze toASFM B 438 <br />HINGE HN PLUGS & DRAIN RUGS: Cast Iron to ASFM A 126 ClassA <br />PROJECT INFORMATION <br />Project: <br />APPROVAL STAMP <br />❑ Approved <br />Address: <br />❑ Approved as noted <br />Contractor: <br />❑ Not approved <br />Engineer: <br />Remarks: <br />Submittal Date: <br />Notes 1: <br />Notes 2: <br />GL5 13 <br />
