Butterfly Valve

Our Central line butterfly valve is produced according to the latest standard mss sp-67 and api-609 of USA and ISO 7005. The production process is managed under the guidance of iso9001(2000version). The valves are completely and fully tested follow api-598, fluid static force, gas force and overall performance of valve are completely and fully carried out following standard of api-598. Thus the zero leakage and high quality are ensured.We are capable of supplying butterfly valves with size ranges from dn-dn600, pressure from dnl0-16. In the meanwhile, we also adopt European and American design standard for different requirements.Our butterfly valves would be applied to:1. Pipeline flange system of iso9005-1992, pn1.0-pn 1.6.2. Pipeline flange system of asme/ANSI bl6.5-1996, cll25 class, cll50 class.3. Pipeline flange system of jis b2211~2213-1996 and pn 0.5-1.6(5d,10k,16k)4. Pipeline flange system of GB/t 9113-2000and pn 1.0-1.6The connection dimension of actuators for the our butterfly valve could be made per is05211 and American national standard or customized.Once you choose our valves, you will be rewarded with simple operation, reliability, low abrasion, small torque, lighter weight. The valves could be easily equipped with pneumatic and electronic actuators according to different requirements.Key features of our butterfly valves:1. Manufactured per mss sp-67 and apl 609;2. Tight sealing and zero leakage under rated pressure (1.0mpa and 1.6mpa);3. Advanced multi-sealing design to free valve body from direct contact with working media and to ensure zero leakage.4. Scientific design for the sealing surface of valves eat to make a tight connection between the seat and valve body, between the seat and flange without any additional accessories.5. Advanced valve shape and mounting pattern design to ensure a better sealing, smaller torque, bigger flow and lower fluid resistance, a swell as flexible two?? Side connection.6. Designed and produced based on multi-standard system so the valve could be applied to flanges of various type, thus the valve enjoys excellent interchangability.7. With top flange make per ISO 5211, the valve could be easily mounted with actuators (pneumatic, electronic and lever). Because all the parts are undergone preservative treatment, the valve could be applied to hard environment.
