31 www.morbros.com AST Spill Prevention Equipment 9095 C 9095 DS AST Overfill Prevention Valve Designed for use on low profile top loading storage tanks that require a high level shut-off. Once the product reaches the preset level, the valve will close and allow minimal liquid to pass through to relieve the fill line pressure. A tight fill connection is required for operation. The valve can be retrofitted on existing tanks and fits a 2” opening. This valve accepts a 1½ male threaded drop tube (not included). Typical flow rate is 60 GPM at 60 PSI pressure drop. Typical flow rate is 26 GPM at 10 PSI pressure drop. Minimum requirements: 10 PSI and 5 GPM. Fig. 9095DS Construction Details Adaptor… anodized aluminum Part A or Part F Body…anodized aluminum Float...nitrophyl-N Plunger and dashpot…brass Upper tube and float guard...aluminum Linkage...stainless steel Shut off mechanism...anodized aluminum Features 1. Valve available in preset shut off heights of 2”, 4”, or 6”. 2. Immediate and cushioned shutoff…full flow up to within 1-2 seconds of closing and no abrupt kickback or jolt, or startling noise in the line when valve closes. 3. Dry disconnect…after shut off product is allowed to automatically drain from the highest point so fill nozzle can be removed without spilling. 4. Simple mechanics…minimum moving parts. Shutoff is activated by basic hydraulic principle with no springs, levers or complicated sequence leading to closure. Size Maximum Maximum Pressure Viscosity 2" 100 PSI 150 Centistokes NOTE…For use on clean product only. Not suitable for motor oil. AST Overfill Prevention Valve Designed for use on low profile top loading storage tanks that require a high level shut-off up to 1.25 inches to the top of the tank.
