OPW 10 SERIES E iENCY SHUT-OFF VALVES I OPW 10 Series Emergency Shut-off Valves are installed on fuel supply lines beneath dispensers at grade level to minimize hazards associated with collision or fire at the dispenser. If the dispenser is pulled over or dislodged by collision, the top of the valve breaks off at the integral shear groove, activating poppets and shutting off the Flow of fuel. Single -poppet models shut off supply flow, while double -poppet models shut off supply as well as prevent release of fuel from the dispenser's internal piping. The base of the Emergency Valve is securely anchored to the concrete dispenser island through a stabilizer bar system within the dispenser sump or pan to ensure proper shearing action. The valve base is secured to the stabilizer bar using a three-point boss mount system or with a U -Bolt Kit. Valve inlet (bottom) connections are female pipe threads and outlet (top) connections are available with female threads, male threads, or a union fitting. Other options include suction system models with a normally closed secondary poppet which maintains prime, and models with external threads on the inlet body which connect to secondary containment systems. Features ♦ High Flow Capacity —The primary poppet is held out of the Flow stream while the secondary poppet is held normally open to minimize head loss across the valve and to protect the poppet seals from damage and erosion. True 1/e' and 2" body sizes ensure maximum flow. ♦ Fire Protection —A fusible link trips the valve closed at 1650 F to shut off fuel supply to the dispenser. *Main Poppet Seat Integral to the Top Assembly — Having the main poppet seat as an integral part of the valve top assures a new, clean seating surface is installed each time the top is replaced. This design also ensures that the integrity of the seal between the valve top and bottom is verified during line testing and allows full inspection of the main poppet when the top is removed.

Patented Thermal Relief Valve Air Test Port Secondary Po Fusible Ll, Nickel -Plated, Teflon -Coated Main Stem Main Poppet *Multiple Mounting Options— Valves are boss -mounted to stabilizer bars in sumps and pans or mounted to bars embedded in the island with U -Bolt kits. Versatile Combination Body (boss mounUU-Bolt mount) models are available to accommodate most mounting applications with one valve style. ♦ Underwriters Laboratories — Listed for use with gasoline and 85% and 100% methanol. All OPW 10 Emergency Shut -Off Valves meet V� requirements of UL STANDARD 842. ♦Duragard%Coat Finish — Provides superior corrosion resistance. NOTICE: As per NFPA 30A, electrical supply to the submersible pump must always be disconnected before servicing meters, dispensers or emergency shut-off valves. IMPORTANT NOTICE: When mounting the OPW 10 Series Emergency Shut-off Valves, the anchoring system employed must withstand a force greater than 650 ft. pounds per valve. NFPA Code 30A, Automotive and Marine Service Station Code, requires that the automatic closing feature of emergency shut-off valves be checked at least once per year by manually tripping the hold -open linkage. OPW recommends the use of PISCES'" Stabilizer Bar Support System for proper mounting of 10 Series Valves. OPW 10S Stabilizer Bar Assembly The OPW 10S Stabilizer Bar Assembly is used in installations where no valve mounting system exists. When properly imbedded into the island concrete, 1 OS holds the OPW 10 Series valves rigidly in place to assure proper shearing action. The 1 OS assembly includes all necessary installation hardware. OPW 1011W Wrench The OPW tORW Wrench is used to install , and remove 1X" OPW 10 Series Emergency Shut-off Valves and is designed to prevent stress to the shear section of the valve dur- ing installation. This wrench is made of ductile iron and has a lx` diameter boss for use with a pipe wrench, and a hole for a /' diameter rod.
