2.Instruction
  1. This valve is two wires valve, of which when red wire is for opening valve that connects to "-" pole and closing valve that connects to "+" pole; when black wire is for opening valve that connects to "+" pole and closing valve that connects to "-" pole. Motor resistance 21Ω.2
  2. .Valve opening process is that when red wire connects "-" pole and black wire connects "+" pole. And the total time for opening valve is 5s.

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 at min.

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 modified material, and the transmission structure will not be deformed in inferior gas;

— Short switch time within 1 second;

— The drive mechanism is compact 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.
