3.Valve closing process is that when red wire connects "+" pole and black wire connects "-" pole. And the total time for closing valve is 300ms
4.The voltage of valve both ends shall not be less than 3V when the system open-close valve.
5.If the parameters and structure of this internal valve changes, our company will promptly inform your company
A.Key technologies:
— The screw is made of modification material, and the transmission structure will not be deformed in inferior gas;
— Short switch time within 1 second;
— The drive mechanism is compacted with stable performance;
— Guiding element is used to achieve the rotation of the screw motor valve, which is not only stable and reliable, but also easy to operate.
B.Main parameters:
Working medium: natural gas, liquefied petroleum gas;
Flow range: 0~4m3/h
Operating voltage: 2.5 to 5.5V;
Operating current ≦80mA
Opening time: ≤1S; Closing time: ≤1S
Working life: 10,000 times;
Service life: ≤12 years
C.Advanced Technology(characteristics):
— The seal structure is changed from integral seal to segmented seal to avoid the excessive deformation of the rubber and breakage;
- The internal air pressure of the segmented sealing mechanism can be automatically released, which improves reliability;
- The overall structure is compact, suitable for installation in a variety of ways;
- The aluminum valve body can be placed in the pipeline to make an external motor valve;
- Low power consumption greatly improve usage time of the control system;
- Short switch time, small current and good explosion-proof performance.
