ASAHI AV - JAPAN > > ASAHI AV Manual Valves > > Butterfly Valves Butterfly Valves Product List * BUTTERFLY VALVE TYPE 57( 40-350mm) [ 1 1/ 2-14inch] Excellent Sealing Performance Sealing performance has been improved due to its specially designed seat " PAT pending" . Lowered Operating Torque Required operating torque has been reduced by applying specially designed seat. * BUTTERFLY VALVE TYPE 56( 400mm) [ 16inch] Step Further to All Plastic TYPE 56 with lever operator butterfly valve which metal parts are reduced as much as possible. Easy Transformation of Operation Devices Application of modular design on top flange provides the valve with flexible and easy change of operation types, from lever to gear and from manual to automatic and so on. * BUTTERFLY VALVE TYPE 75( 450-600mm) [ 18-24inch] Long stem type and chain drive type are available on special request. * PDCPD BUTTERFLY VALVE( 700-1200mm) [ 28-48inch] High Corrosion Resistance The body and disc are made of PDCPD. And the corrosion-resistant resin, covering the whole contact surface, makes the valve highly resistant against chemical and sea water. Light Weight PDCPD having 1/ 4 or less the specific gravity of iron, the PDCPD BUTTERFLY VALVE is significantly lighter than a metallic butterfly valve. * ROTARY DAMPER( 40-600mm) [ 1 1/ 2-24inch] DAMPER STYLE is Designed for Flow Control. * BUTTERFLY VALVE TYPE 55( 50-250mm) [ 2-10inch] Extreme Corrosion Resistance All of the wetted parts are completely covered with PTFE, which can result in excellent performance against a highly corrosive media. Improved Cv Value Thinner disc makes the area of flow passage wider and the Cv value is improved as a result. * LUG BUTTERFLY VALVE TYPE 57L 80, 100, 150mm [ 3, 4, 6inch] Incorporated Lug Function into the Type57 Butterfly Valve Design Easy for Maintenance Easy to draw out fluid No-leakage under full line pressure. * PVC LUG BUTTERFLY VALVE TYPE 57L [ ANSI 3-12inch] Incorporated Lug Function into the Type57 Butterfly Valve Design Easy for Maintenance Easy to draw out fluid No-leakage under full line pressure. * BUTTERFLY VALVE TYPE 56D, 75D Type56D: 400mm( 16inch) Type75D: 450mm 600mm( 18inch 24inch) Easy Transformation of Operation Devices Application of modular design on top flange provides the valve with flexible and easy change of operation types, and from manual to automatic and so on. * BUTTERFLY VALVE TYPE 57L-IS Short Face-to-Face Dimension The Valves are Designed to Comply ISO5752 Short Face-to-Face dimension and allowed Replacement of Common Metal Valves. Easy Piping Maintenance It is not necessary to remove fluid from the pipe line.
