Product Overview DQF series of electric valve is the company specifically for the cement plant raw material library, silos and other inflatable control the development of a patented product. Its action life of one million times, closing time is 2 seconds / time (0 ~ 90 °), two targets were exceeded imports of similar products, is ideal for contemporary dedicated switch valve pneumatic control. Currently, the major domestic cement and Design Institute has generally choose this valve, have eliminated the common solenoid valve, pneumatic solenoid valve, pneumatic valve type 0, traditional electric valve and rotary air distributor, the country has 300 dry cement production line to apply this valve, and exported to Thailand, Vietnam, Laos, Pakistan, Saudi Arabia and Chile and other countries through international and major cement Sinoma Design Institute. Product parameters DQF electric valve open in the absence of external signals (relay electrical signals) of the cases, the role of the power supply, keeping fully closed electric lock, then dial in the fully closed position indication, indicator switch electrical signal (electrical relay ) no output. After adding turn signals, internal mini relay, main motor rotation immediately, on its drive shaft pinion synchronous rotation, drive shaft and large gear and stainless steel ball synchronous rotation, after 2 seconds, the valve is in the fully open position, in the limit Under the role switch, the motor stops rotating, and remain locked while the electrical signal indicating the switch is touch operation, the switch signal output enable control room lights corresponding instructions, then dial in the fully open position indication. Conversely, when the turn signals disappear, the motor immediately reverse, after 2 seconds, in effect reverse limit switch, the motor stops, when the valve is fully closed position. Product specifications DQF electric valve models: DQF-15, DQF DN15, DQF-25 DN25, DQF-32, DQF DN32, DQF-40, DQF DN40, DQF-50, DQF DN50, DQF-65, DQF DN65, DQF- 80, DQF DN80, DQF-100, DQF DN100, DQF-125, DQF DN125, DQF-150, DQF DN150, DQF-200, DQF DN200
