2 New nti-condensation luminum Diecast Body 04MHLV 7V/8V 77ZNV-Z Revolutionary super light aluminum diecast body butterfly valve Larger Flow Rate Improved seat design (new cosine-curve seat) with rib disc (*except 40mm type) can provide a larger flow rate and larger Cv value than existing models by maintaining mechanical strength of the disc. *atent pending Ultra Super Light Weight Easy installation due to lighter (0% lighter than 2Z on mm types) and alignment ribs. mm 0mm mm Remarkable nti-condensation Capability Better anti-condensation capability is achieved by utilizing a high performance engineering plastic column. The high performance engineering plastic has excellent features such as low water absorption, high corrosion resistance, heat resistance, nonflammability as well as shock resistance, which is approximately four times that of hard VC material. Features Examples of (Kg) with gear operator Conventional 2Z-2I 77Z-2J (Iron body) Room temperature (degree C) (luminum diecast body) The graph below shows anti-condensation performance under degrees C cold moisture No condensation will be formed below the line on 77Z-2J, mm to mm No condensation will be formed below the line on 77Z-2J 40mm and 77Z-2! 2mm and 00mm Humidity (%) Engineering lastic Housing of Gear operator with stainless steel worm shaft The high performance engineering plastic housing and stainless steel worm shaft are standardized to prevent corrosion for the 2J type worm gear operator. Silicon Seat (mm to mm) The silicon seat is designed for chlorinated hot water applications for sanitary use in the 778Z. S Disc 778Z The S lined disc (poly phenylene sulfide with stainless steel core) is available up to mm and is an optimum product for corrosive fluids (subject to the performance of the rubber material). It works under the same concept as plastic butterfly valves whose contact parts with fluid consist of a plastic disc and rubber seat. NV-Z-01 21

General description Dew condensation 04MHLV 7V/8V 77ZNV-Z This revolutionary aluminum diecast body butterfly valve is an extended model of our best selling 2Z. The high performance engineering plastic top plate (patent pending) with aluminum diecast body can prevent dewcondensation and allow auto-actuation with the ISO top flange design. 216 NV-Z-02
