Companies adhere to the "quality first, integrity management" purposes, to provide customers with affordable products and perfect after-sales service, welcome to buy! A pneumatic lined ball valve Product Overview Q641F46 pneumatic valve is lined for a variety of corrosive media pipeline designed to automatically open and close control, Q641F46 pneumatic lined ball valve is widely used in petroleum, chemical, dyes, acid system alkali and other industries, is currently one of the best anti-corrosion valve device selection. PTFE lined ball valve pneumatic fluorine plastic lining, investment casting shell with high strength, appearance and smooth contact with the liquid portion of all fluorine plastic, so the pneumatic lined ball valve can be long-term in the range of -50 ℃ ~ 180 ℃ any concentration used in corrosive piping line work. Second, the main technical parameters of pneumatic lined ball valve nominal diameter DN (mm) 15 ~ 300 actuator models GT, AT, AW series of single and double acting pneumatic actuator nominal pressure (MPa) PN1.0,1.6 MPa supply pressure of 0.4 ~ 0.7MPa valve in the form of a two-stage valve (floating sphere, fixed sphere) air interface G1 / 4 ', G1 / 8', G3 / 8 ', G1 / 2' of connection flange Ambient temperature -30 ~ + 70 ℃ spool in the form of 'O' type poppet action in the form of single-acting actuators, double acting actuator packing polytetrafluoroethylene (PTFE) can be equipped with accessories positioners, solenoid valves, air filter pressure reducer, to secure his position valve , flow characteristics limit switch, valve position transmitter, handwheel institutions approximation using the new quick-open pneumatic actuators, double acting and single acting (spring return), rack and pinion, safe and reliable; large diameter valves using AW series pneumatic actuator fork-type transmission, reasonable structure, output power, a double-acting and single-acting. 1, gear dual-piston, output torque, small size. 2, the choice of aluminum alloy cylinder material, light weight, beautiful appearance. 3, at the top, bottom mounting manual operating mechanism. 4, the rack can be adjusted opening angle connector, the rated flow. 5, the actuator feedback signal indicative and optional accessories charged to automate operations. 6, IS05211 standard provides a convenient connection to install the replacement product. 7, both ends of the adjusting screw allows the sections of standard products in the 0 ° and 90 ° with the adjustable range of ± 4 °. To ensure the accuracy of synchronization with the valve. Operating range 0 ~ 90 ° soft seal leak amount Q: zero leakage Temperature PTFE≤180 ℃ basic error with positioner: less than ± 2% of full stroke dead zone locator: less than 2% of full stroke adjustable range of 250: an actuator configured GT, AT, ST, AW series single and double acting pneumatic actuator control mode switch two controls, 4-20mA analog control three, lined ball valve pneumatic actuators actuator technology parameter model GT, SR, ST, AT, AW series of single, double acting pneumatic actuator supply pressure 0.4 ~ 0.7MPa Air Connection G1 / 4 ', G1 / 8', G3 / 8 ', G1 / 2' Ambient temperature -30 ~ + 70 ℃ action form single acting actuators: air-to-close (B) - When the loss of gas valve opening (FO); open air (K) - when the loss of gas valve off (FC) double acting actuators: air-to-close (B ) - loss of gas when the valve position to maintain (FL); open air (K) - loss of gas when the valve position to maintain (FL) can be equipped with accessories locator, solenoid valve, air filter pressure reducer, to secure his position valves, stroke switches, valve position transmitter, the four hand wheel, pneumatic lined ball valve main parts and materials Part Name Material Body, bonnet WCB + F46 304 (CF8) + F46 316 (CF8M) + F46 316L (CF3M) + F46 sphere 2Cr13 + nitriding +46 304 + 46 316 + 46 316L + 46 stem 2Cr13 + 46 304 + 46 316 + 46 316L + 46 seat ring PTFE, carbon fiber + on the V-type PTFE packing PTFE packing Haiqiao Yap valve to provide you with professional pneumatic lined ball valve] [Q641F46 solutions, if there is any doubt, we will try our best to answer your questions!
