The OPW 61 SO allows easy installation(without breaking concrete)and requires no special manholes. The OPW 6150 s a two-stage _hut-oft valve, When the liquid level rises to about 95"0 of tank capacity, the valve mecnan sm s released, closing automatically .vith the;low. Th,s reduces the flow rate to aeproximateiv 5 opm through a bvpaSs valve The aoeratcr may then stop the`,llirg orecass and disconnect and drain;he delivery hose.As long as:he iquid exceeds the 951,;;eves, the valve will close automatically each time delivery Is attempted. If the delivery is net stopped and the liquid uses to about 98%of tank capacity, 'he bypass valve closes completely. No additional liquid can flow into the tank unbi the level drops below a reset pont. Models of the 61-SO are available to meet virtually any UST application including two-point, coaxial,poppeted coaxial and remote fill. The 61SO-3000 provides Iwo-point overfill protection for 3"riser pipes, and the 6150-1000 and 61SO-100C(CARB)feature a grooved-tube design for use with tank gauging systems. Methanol and CARS(vapor-light)approved models are also available. The OPW 61 SO is approved by the New York City Fire Department (Approval#4902) IMPORTANT In order to prevent product spillage from the Underground Storage Tank(UST),property maintained delivery equipment and a proper connection at the tight-frll adaptor are essential. Delivery personnel should be managed and trained to inspect delivery elbows and hoses for damaged and missing parts.They should always make certain there is a positive connection between the adaptor and elbow. If delivery equipment is not property maintained,or the elbow is not securely coupled to the adaptor, a serious spill may result when the OPW 6150 closes,causing a hazard and environmental contamination. NOTE: The OPW 61SO is designed for use on tight-fill gravity drop applications only. Do not use for pressure fill applications.
