Electric butterfly valve flange 



 Electric butterfly valve flange 

 Uses and Features 

 Electric soft seal butterfly valve made of rubber sealing flange and carbon steel or stainless steel butterfly valve plate, stem form. ≤ 120 ℃ for temperature, such as textile, paper, food, pharmaceutical, chemical, oil, electricity, and other drainage, gas pipes for regulating traffic and closure of the role of media. Its main features are: 
 1, novel design, reasonable, unique structure, light weight, open and close quickly. 
 2, operating torque is small, easy to operate, saving smart. 
 3, can be installed anywhere, easy maintenance. 
 4, the seals can be replaced, sealing performance and reliable way to achieve zero leakage seal. 
 5, sealing materials resistant to aging, corrosion resistance, long service life.

 Executive body 

 Type: QY Series Features: 
 1. Powerful: intelligent, modulating, switching. 
 2 small size: the volume equivalent to only about 35% of similar products. 
 3 Easy to use: single-phase power, simple wiring; using original ball protruding structure, so that observation is more convenient; free refueling point inspection-free, waterproof anti-rust, installed at any angle. 
 4 protection device has a double limit, thermal protection, overload protection. Transit time 15 seconds, 30 seconds, 45 seconds, 60 seconds. And with manual functions. 
 5 Intelligent NC: built-in modules using advanced computer chip, and intelligent control software directly to the receiving computer or industrial instruments such as the output of standard signals (4-20mA DC / 1-5VDC) to achieve the intelligent control valve opening and precise positioning. 
 Can also be used or NA Series 3810 Series electronic actuators. May choose PSQ series or DYR series. ≥ DN 200 diameter valves generally use the 380VAC electric actuator. Domestic brands such as Ruiji, Australia Rostock, Yangzhou power, two-day, Lan Ling, etc.; foreign brands Britain Rotork, Bernard, France, Germany, Ou Ma, Xi Bosi, Germany (Siemens) and so on.
