2. Operating Instructions

1)The ball valve is driven by the motor drive mechanism, and then driving the ball to achieve opening / closing valve.

2)This valve has 4 control wires, of which red / black is the motor wire and 2 yellow wires are  switch wire.

3)Valve opening process: when red wire connects “-” pole and black wire connects “+” pole, detecting the 2 yellow wires are conduction, then the opening valve is completed.

4)Valve closing process: when red wire connects “+” pole and black wire connects “-” pole, detecting the 2 yellow wires are conduction, then the closing valve is completed.

a.Key technologies:

- Dividing the ball valve into a valve unit and a drive unit for controlling the opening and closing of the valve unit make it convenient to manufacture;

- an accommodating groove is installed on one side of the inner wall of the valve body,One side of the outer wall of the valve body is provided with a groove on the accommodating grooves which an accommodation space that extend inward corresponds to, and one end of the valve rod is disposed in the groove through the accommodating grooves, and the other end is connected with the driving unit; stop collar and the elastic elements are matched and installed at the inlet or the outlet of the valve body with more accurate ball body position.   moderate opening and closing force, which is safe and reliable;

- The elastic mechanism is installed in the valve body to limit the contact area and compression of the ball and sealing element. Even if it is subjected to dimensional changes caused by different temperatures, it will not leak with good sealing effect, small friction and low power consumption.

b.Main parameters:

Working medium: natural gas, liquefied petroleum gas;

Flow range: 0~6m³/h

Operating voltage: 2.8 to 5.5V;

Operating current ≦80mA

Opening time: ≤5S; Closing time: ≤5S

Working life: 10,000 times;

Service life: ≤12 years

c.Advanced Technology (characteristics):

- Overcoming other products’ problem that the friction coefficient of rubber sealing elements is large;

- The principle of spring compression is adopted, which has an anti-lock function after lubricating oil failure;

- Critical components will not leak due to dimensional changes at high and low temperatures,ensuring product reliability;

- Use bidirectional switch signal control to make the switch in place without damage when it faces impact.
