1) Installed on fuel supply lines beneath at grade level to minimize hazards associated with collision or fire at the dispenser 2) If the dispenser is pulled over or dislodged by collision, the top of the valve breaks off the flow of fuel 3) 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 4) Base securely anchored to the concrete dispenser island through a stabilizer bar system within a U-Bolt assembly 5) Valve inlet (bottom) connections are female pipe threads and outlet (top) connections are available with female threads, male threads, or a union fitting 6) Other options include suction system models with a normally closed secondary poppet which maintain prime, and models with external threads on inlet body which connect to secondary containment system 7) Materials: A) Body: Cast iron (spray-paint) B) Seal: Buna-N, O-ring 8) Flow rate: 0-120L/m 9) Working pressure: 0.2MPa 10) Valve closing speed: 0.5s 11) Lowest shut-off temperature: 75oC 12) Medium: Water, gasoline, diesel and kerosene 13) Operating environment: -30oC~+55oC 14) Fire protection: A fusible link trips the valve closed at 75oC to shut off fuel supply to the dispense 15) Integral test port: A 3/8" test port allows the piping system to be air tested without breaking any piping connection 16) Low-profile tops: Female and union-top double-poppet valves have a low-profile top to allow upgrading from Aile single-poppet valves without changing existing piping 17) Multiple mounting option: Valves are boss-mounted to stabilizer bars in sumps and pans or mounted to bars embedded in the island with U-Bolt kits 18) Versatile combination body (boss mount/ U-Bolt mount) models are available to accommodate most mounting applications with one valve style 19) 100% factory tested 20) Ordering specifications: A) QDYH 901-911 B) Inlet thread: NPT1+1/2", BSP1+1/2" (female) C) Outlet thread: NPT1+1/2", BSP1+1/2" (female, male) D) Poppet configuration: Single, double 21) Replacement parts: A) Key 1: Protect pin B) Key 2: Cap (single), weight 0.795kg C) Key 2: Cap (double), weight 0.895kg Outer packing: 6pcs/ctn Carton dimensions: 37.5 x 13.5 x 39cm N.
