BUTTERFLY VALVE WITH ELECTRICAL ACTUATOR 1、 VALVE WITH ON-OFF ELECTRIC ACTUATOR 2、 VALVE WITH ROTARY MODULATING ELECTRIC ACTUATOR Overview： u electric actuator FOLWX series electric actuator is used for controlling 0°～270° rotation of the valves and other similar products, such as butterfly valve, ball valve, damper, flapper valves, cock valves, etc. It’s widely used in petroleum, chemical, water treatment, shipping, paper making, power plants, heating, light industry and other industries. It drives by 380V/220V/110V AC power. Control signal is 4-20mA current signal or 0-10V DC voltage signal, enables move the valve to the desired position, achieving its automation, maximum output torque is up to 4000N•m.. u Butterfly Valve using flat stem without pin of connection,driving & reliable sealing of double direction were strengthened and allowing the disc standing freely in the middle of line,and reducing the torque of opening & closing valve and isolating completely media so that eliminate leakage & corrosion. Valve specific information: Applicable temperature: EPDM：-35℃~ +120℃ NBR：-25℃~ 90+℃ PTFE：-40℃~+150℃ FPM：-29℃~+205℃ Body material: Ductile Iron Cast Iron Cast Steel Stainless Steel Disc material:Stainless Steel Ductile Iron Coated by Nickel Ductile Iron Coated by Nylon Ductile Iron Coated by Vulcanized Rubber Stainless Steel 316L Duplex Stainless Steel 1.4669 & 1.4529 Special for Desulfurization Aluminum Bronze Seal ring material:NBR EPDM Silicon Rubber\ High-temperature EPDM Wear Resistance EPDM PTFE Applicable medium:Water,Salt,Acid,Soda,Natural Gas,Air,Mellow,Oil,Food&Steam etc. Suitable flanged：PN6/10/16kg、 ANSI CLASS 150/300 Working pressure：PN6、PN10、PN16 Coated surface:Epoxy polyester, Nylon 11,Paint, Epoxy
