The Treloar-OPW High Flow Automatic Nozzles are designed to provide reliable performance for bulk service operations of petroleum products with a viscosity less than 120 SSU. They are ideal for truck, bus, diesel locomotive and prime mover refuelling as well as drum-filling and home deliveries of fuel and heating oil. Flow rates from 23 to 325 litres/min (5-72 gpm) are achievable with these two nozzles. Each nozzle has an automatic shut-off characteristic when the product being pumped rises a short distance (approx. 10 mm.) beyond the end of the spout of each nozzle. Features:
