Electric telescopic valve for temperature ≤ 80 ℃, nominal pressure ≤ 1.6MPa food, medicine, chemical, petroleum, electric power, textile, paper and other water supply and drainage, gas pipes for regulating traffic and closure of the role of media, with compensation pipe thermal expansion and contraction functions. Its main features are as follows: 

 1, novel design, reasonable, unique structure, light weight, easy to operate, open and close quickly; 
 2, telescopic valve for regulation and closure in addition to the role of compensation arising from thermal expansion and contraction pipe temperature function, but also for the installation of replacement, repair the valve with ease. 
 3, seal replacement parts can be adjusted, sealing performance and reliability.

 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.
