The shut-off valve is an integral <br />part or the drop tube used for gravity filling. The OPW 6150 allows easy installation (withou( <br />breaking concrete) and requires no special manholes. <br />The OPW 61 SO is a two-stage shut-off valve. When The liquid level rises to al,out 95% of lank <br />capacity, the valve mechanism is released, closing automatically with the flow. This reduces the <br />now rale to approximately 5 qpm through a bypass valve. The operator may then stop The filling <br />process and disconnect and drain the delivery hose. As long as the liquid exceeds the 95% level, <br />the valve win close automatically each time delivery is attempted. <br />If the delivery is not stopped and the liquid rises to abnut q8% of lank capadly, the bypass <br />valve closes completely. No additional liquid can now into the lank until the level drops below a <br />reset point. <br />Models of the 61SO are available to meet virtually any UST application including two-point, <br />coaxial, Poopeled coaxial and remote fill. The 61SO-30W provides two-point overfill protection for <br />3" riser pipes, and the 61SO-1000 and 61S0 -100C (CARO) feature a grooved -tube design for use <br />with lank gauging systems. Methanol and CARO (vapor -tight) approved models are also available. <br />The OPW 61S0 is approved by the New York City Fire Department. (Approval 04902) <br />PAGE 05 <br />IMPORTANT <br />In order to prevent product spnlage from the Underground Storage Tank (UST), properly maintained delivery equipment and a proper <br />connection at Ilie fight -tel adaptor are essential. Delivery personnel should be managed and trained to inspect delivery elbows and <br />hoses for damaged and missing parts. They should always make certain there is a positive connection between the adaptor and <br />elbow. It delivery equipment is not properly maintained, or The elbow is not securely coupled to the adaptor, a serious spill may result <br />when the OPW 6150 closes, causing a hazard and environmental contamination. <br />NOTE: The OPW 61SO is designed fur use on fight -fin gravity drop applications only. Do not use for pressure fill applications. <br />Features: <br />* Simple, Easy and Quick Installalion <br />No excavation or special manholes <br />required. <br />* Economical . Costs a traction of <br />expensive. complicated and difficult <br />to install valves. <br />* Furnished Complete - Supplied with <br />new upper and lower drop lubes, <br />mounting hardware and thorough <br />Instructions for quick job site time. <br />* Completely Automatic Operation - No <br />prer:hecks to Perform. no resets, and no <br />overrides to be broken or abused. <br />* No Pressurization of The Tank - <br />Operates directly from liquid level. <br />• VWIl Accept a Dipstick for Gauging. <br />* Retrofits Directly • For both new and <br />existing tanks with 3" or 4" till risers. <br />* Quick Drain Feature - Automatically <br />drains hose when head pressure is <br />relieved. <br />* Hest Flow Rate in The Industry.* <br />11331 witnessed by Bowser-Momer.

ResulO available <br />upon request. <br />Advantages of Overfill Prevention <br />Compart!d to Overfill Warning S_ystoms: <br />* Completely Automatic Operation - <br />Does not rely on the alertness or speed <br />of response of the delivery altendanL <br />for certainly of overfill prevention. <br />* <br />Keep the Top of UST "Dry," per <br />EPA Requirements - Ellrrinating <br />possible teaks at loose bung fittings <br />and the need fm double containment <br />on vent lines. <br />♦ Does Not Rely an Pressure in the <br />UST to Stop Flow - Allowing fester fill <br />limes and reducing spin risk. <br />♦ Speeds Delivery Operations - <br />Product flows unimpeded into the tank <br />until the hose "kick" that accompanies <br />the valve shut-off provides a clear <br />signal that the liquid has reached the <br />shut-off level. <br />* Simple and inexpensive lnstallaUon - <br />In both two-point and coaxial Bq <br />applications, no additional excavation, <br />manholes or vent piping are required. <br />Certifications <br />NY City Fire <br />and U10 9!
