Benefits Of Electric Flanged Butterfly Valves
Electric flanged butterfly valves can provide you with reliable fluid control solutions, improve your production efficiency and gain more market share. Flanged butterfly valve can replace parts according to your needs, including valve body material, seal material, valve plate material, etc. Available in ANSI standard, JIS standard, DIN standard or GB standard to fulfill your needs.
Used with electric actuators, it can remotely control valve on/off through signal control or Bluetooth control, helping you improve production efficiency.
