NMI <br />AST Overfill Prevention Valve <br />Patent 5832953... installed at the fill port of a <br />aboveground storage tank. Used in a tight fill <br />application, the valve terminates flow of <br />product when the liquid level reaches a preset <br />warning level (90-95% full). The valve is <br />installed on a standard NPT male connection <br />when used with the quick disconnect or femal <br />adaptor. The 2" valve can be used in conjunc- <br />tion with the Morrison Fig. 518 and 515 lines c <br />AST spill containers for added spill protection <br />When installed to manufacturers requirements <br />the OPV valve can help eliminate environmen- <br />tally hazardous spills. All models are supplied <br />with an adaptor to mount to Morrison Fig. 419 <br />aluminum drop -tubes. ULC listed. <br />Fig 9 095A -AV ... compatible with aviation fuel <br />systems and the Morrison Fig. 539 Diffuser. <br />Fig 9095ATM ... mechanical test mechanism, <br />includes 0200 top, aluminum, 2" or 3". <br />Construction Details <br />Adaptor... aluminum (hard -coat anodized) <br />Female adaptor... ductile iron <br />Body... anodized aluminum <br />Plunger and dashpot... brass or nickel plated <br />Shaft, linkages and hardware... stainless steel <br />Piping ... steel (epoxy coated) <br />Features <br />1. Adjustable float (1'/z") ... for setting the precise level <br />of shutoff in the field and allowing it to be done <br />using standard length pipe nipples. <br />2. Immediate and cushioned shutolf ... full flow up to <br />within 1-2 seconds of closing and no abrupt kickback <br />or jolt, or startling noise in the line when valve <br />closes. <br />3. One piece adaptor/coupler casting ... no extra seams <br />and joints to leak when top portion is under pressure <br />from closing. <br />4. Dry disconnect... after shut off product is allowed <br />5A to automatically drain from the highest point so fill <br />nozzle can be removed without spilling. <br />5. Simple mechanics... minimum moving parts. <br />Shutoff is activated by basic hydraulic principle <br />with no springs, levers or complicated sequence <br />leading to closure. <br />Code Compliance <br />NFPA 30, 30A, UFC, BOCA, SBCCI/SFC and PEI <br />RP200. <br />909 <br />.Size <br />Maximum Pressure <br />Maximum Flow <br />Maximum Viscosity <br />2" <br />100PSI <br />125gpm <br />150 Centistokes <br />3" <br />lo0PSl <br />300gpm . <br />60 Cent, istokes <br />AST Overfill Prevention Valve <br />Designed for use on low profile tanks that require <br />a high level shut-off. The valve terminates the fill <br />when the product reaches the preset level. The <br />valve can be retrofitted on existing tanks and fits <br />into a 2" opening. A tight fill connection is <br />required for operation. <br />Sold with either a 2" Part F Male Threaded <br />Adaptor or a 2" Part A Female Threaded Adaptor. <br />Typical flow rate is 53 GPM at 30 PSI. <br />Size Maximum Maximum <br />Pressure Viscosity <br />2" 106P81 ": 150 Centistokes <br />'BSP Threads Available <br />Fig. 9095S <br />Construction Details <br />Adaptor... aluminum (hard -coat anodized) <br />Body... anodized aluminum <br />Float... polypropylene <br />Plunger and dashpot... brass <br />Upper tube and float guard ... brass <br />Shut off mechanism... anodized aluminum <br />Features <br />1.
