OPW 10 SERIES EMEKGENCY SHUT-OFF VALVES <br />OPW 10 Series Emergency Shut-off Valves are installed on fuel supply <br />lines beneath dispensers at grade level to minimize hazards associated with <br />collision or fire at the dispenser. If the dispenser is pulled over or dislodged <br />by collision, the top of the valve breaks off at the integral shear groove, <br />activating poppets and shutting off the flow of fuel. Single -poppet models <br />shut off supply flow, while double -poppet models shut off supply as well as <br />prevent release of fuel from the dispenser's internal piping. The base of the <br />Emergency Valve is securely anchored to the concrete dispenser island <br />through a stabilizer bar system within the dispenser sump or pan to ensure <br />proper shearing action. The valve base is secured to the stabilizer bar using <br />a three-point boss mount system or with a U -Bolt Kit. Valve inlet (bottom) <br />connections are female pipe threads and outlet (top) connections are <br />available with female threads, male threads, or a union fitting. Other options <br />include suction system models with a normally closed secondary poppet <br />which maintains prime, and models with external threads on the inlet body <br />which connect to secondary containment systems. <br />Features <br />♦ High Flow Capacity —The primary <br />poppet is held out of the flow stream <br />while the secondary poppet is held <br />normally open to minimize head loss <br />across the valve and to protect the <br />poppet seals from damage and erosion. <br />True 13 'and 2" body sizes ensure <br />maximum flow. <br />*Fire Protection —A fusible link trips the <br />valve closed at 165° F to shut off fuel <br />supply to the dispenser. <br />*Main Poppet Seat Integral to the Top <br />Assembly — Having the main poppet <br />seat as an integral part of the valve top <br />assures a new, clean seating surface is <br />installed each time the top is replaced. <br />This design also ensures that the <br />integrity of the seal between the valve <br />top and bottom is verified during line <br />testing and allows full inspection of the <br />main poppet when the top is removed. <br />Materials <br />Top: cast iron* <br />Body: cast iron* <br />Disc: M-19 <br />Carrier: zinc plated steel <br />Stem: copper -nickel -chrome plated <br />brass <br />Poppet spring: stainless steel <br />Seal: M-19 0 -ring <br />Packing nut: brass, Teflon® coated <br />Inlet and outlet thread: V/z" NPT <br />(British threads available) <br />*With black Duragard® coating <br />Low Profile <br />Main <br />Poppet Seat <br />Combination <br />Body -_ <br />♦ Reliable Shut-off —A Stainless <br />Steel Main Spring, a Teflon -Coated <br />Brass Packing Nut, and a Copper - <br />Nickel -Chrome Plated Brass Stem <br />are designed to prevent tar build-up <br />and corrosion from interfering with <br />poppet operation after long periods of <br />normal service without activation. <br />♦ Integral Test Port — A N" Test Port <br />allows the piping system to be air tested <br />without breaking any piping connections. <br />♦ Patented Thermal Relief Valve — <br />Relieves excessive pressure build-up <br />caused by thermal expansion of fuel <br />in the dispenser piping system in <br />the event of fire (double -poppet <br />models only). <br />♦Low -Profile Tops — Female and <br />Union -top double -poppet valves have a <br />low -profile top to allow upgrading from <br />OPW single -poppet valves <br />without changing existing piping. <br />Patented Thermal <br />Relief Valve <br />Air Test <br />' Port <br />Secondary <br />:. Poppet <br />Fusible Link <br />Nickel -Plated, <br />Teflon -Coated <br />Main Stem <br />Main <br />Poppet <br />*Multiple Mounting Options— <br />Valves are boss -mounted to stabilizer <br />bars in sumps and pans or mounted to <br />bars embedded in the island with <br />U -Bolt kits. Versatile Combination Body <br />(boss mount/U-Bolt mount) models are <br />available to accommodate most <br />mounting applications with one valve style. <br />*Underwriters Laboratories— <br />Listed for use with gasoline and 85% <br />and 100% methanol. All OPW 10 <br />Emergency Shut -Off Valves meet V� <br />requirements of UL STANDARD 842. <br />♦Duragard®-Coat Finish — Provides <br />superior corrosion resistance. <br />NOTICE: <br />As per NFPA 30A, electrical supply to the <br />submersible pump must always be <br />disconnected before servicing meters, <br />dispensers or emergency shut-off valves. <br />IMPORTANT NOTICE: <br />When mounting the OPW 10 Series Emergency Shut-off Valves, the anchoring system employed <br />must withstand a force greater than 650 ft. pounds per valve. <br />NFPA Code 30A, Automotive and Marine Service Station Code, requires that the automatic closing <br />feature of emergency shut-off valves be checked at least once per year by manually tripping the <br />hold -open linkage. <br />OPW recommends the use of PISCESTm Stabilizer Bar Support System for proper mounting of 10 <br />Series Valves. <br />OPW 10S Stabilizer <br />Bar Assembly <br />The OPW 10S Stabilizer Bar Assembly is used <br />in installations where no valve mounting system <br />exists. When properly imbedded into the Island <br />concrete, 10S holds the OPW 10 Series valves <br />rigidly in place to assureproper shearing action. <br />The 10S assembly includes all necessary <br />installation hardware. <br />OPW 1011W Wrench <br />The OPW 10RW Wrench is used to install <br />and remove 1X" OPW 10 Series Emergency <br />Shut-off Valves and is designed to prevent <br />stress to the shear section of the valve dur- <br />ing installation. <br />This wrench is made of ductile iron and has <br />a 1% diameter boss for use with a pipe <br />wrench, and a hole for a;�' diameter rod. <br />1W <br />
