1 <br />n <br />u <br />1 <br />• • Item #87 <br />Features <br />• High Flow Capacity — The primary poppet is held out of the flow stream while the secondary poppet is <br />held normally open to minimize head loss across the valve and to protect the poppet seals from damage <br />and erosion. True 1 1/2" and 2" body sizes ensure maximum flow. <br />• Fire Protection — A fusible link trips the valve closed at 165° F to shut off fuel supply to the dispenser. <br />• Main Poppet Seat Integral to the Top Assembly — Having the main poppet seat as an integral part of <br />the valve top assures a new, clean seating surface is installed each time the top is replaced. This design <br />also ensures that the integrity of the seal between the valve top and bottom is verified during line testing <br />and allows full inspection of the main poppet when the top is removed. <br />• Reliable Shut-off — A Stainless Steel Main Spring, a Teflon -Coated Brass Packing Nut, and a Copper - <br />Nickel -Chrome Plated Brass Stem are designed to prevent tar build-up and corrosion from interfering <br />with poppet operation after long periods of normal service without activation. <br />• Integral Test Port — A 3/8" (9.5 mm) Test Port allows the piping system to be air tested without <br />breaking any piping connections. <br />• Patented Thermal Relief Valve — Relieves excessive pressure build-up caused by thermal expansion of <br />fuel in the dispenser piping system in the event of fire (double -poppet models only). <br />• Low -Profile Tops — Female and Union -top double -poppet valves have a low -profile top to allow <br />upgrading from OPW single -poppet valves without changing existing piping. <br />• Multiple Mounting Options — Valves are boss -mounted to stabilizer bars in sumps and pans or <br />mounted to bars embedded in the island with optional U -Bolt kits IOUBK-015 (not included). Versatile <br />Combination Body (boss mount/U-Bolt mount) models are available to accommodate most mounting <br />applications with one valve style. <br />• Underwriters Laboratories — Listed for use with gasoline and 85% and 100% methanol. All OPW 10 <br />Emergency Shut -Off Valves meet requirements of UL STANDARD 842. <br />• Duragard®-Coat Finish — Provides superior corrosion resistance. <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 brass <br />Poppet spring: stainless steel <br />Seal: M-19 O-ring <br />Packing nut: brass, Teflon® coated <br />Inlet and outlet thread: 1 1/2" ( 4 cm) NPT (British threads available) <br />*With black Duragard® coating <br />Notice: <br />t As per NFPA 30A, electrical supply to the submersible pump must always be disconnected before servicing <br />meters, dispensers or emergency shut-off valves. <br />irl <br />n <br />
