The OPW 6150 is a two-stage shut-off valve.When the liquid level rises 10 ebuu195%of lank rapacity, the valve mechanism is released,closing automatically will,the How. This reduces the now rale In approximately 5 qpm through a bypass valve. The Oparalor may then stop the filling Process and disconnect and drain the delivery hose.As long as the liquid exceeds the 95%level, the valve will close automatically each lime deliveryis attempted. If the delivery is not slopped and the liquid rises to about 98%of lank caoarily,the bypass valva closes completely.No additional liquid can flow into the lank until the level drops below a resel point, Models of the 6150 are available In meet virtually any UST application including two-point, coaxial,poopeled coaxial and remote fill. The 61SO-30W provides two-point ovefin protection for 3'riser pipes,and the 6150.1000 and 6150-100C(CARD)1e811"a grooved-tube design for use Willi lank gauging systems. Methanol and CARD(vnp(r-09111)approved models are also available, The OPW 6150 is approved by the New York City Fire Deparimenl.(Approval#4902) IMPORTANT — In older to prevent product spillage bran the Underground Storage Tank(UST),properly maintained delivery equipment and a proper connection at the lighl-fill adaptor are essenlial. Delivery personnel should be managed and trained In inspect delivery elbows and hoses for damaged and missing pans.They should always make certain there is a positive connection l ahvann the adaptor and elbow.If delivery equlpmant is rwl property maintained,of the elbow is not securely coupled to the adaptor,a serious spill may result when the OPW 6150 closes,causing a herard and environrireoful contamination. NOTE: The OPW 6150 is designed fur use on light-fill gravity drop applications only. Do not use for pressure fill applications.
