2-wire Ball Valve

Product Details

1.Basic specs

2. Instruction
1、The ball valve is driven by the motor drive mechanism, and driving the ball to achieve opening / closing valve.
2、This valve has 2 control wires, of which blue / white is the motor wire.

3、 Opening valve process: when white wire connects “-” pole and blue wire connects “+” pole, detection of the locked rotor current means the opening valve is completed.
4、Closing valve process: when blue wire connects “-” pole and white wire connects “+” pole, detection of the locked rotor current means the closing valve is completed.
5、If wire is extended by connectors, opening/closing procedures follows the same manner.
6、The voltage of valve both ends shall not be less than 2.5V
7、The driving current of valve control circuit provided cannot be less than the motor peak current.
8、If the parameters and structure of this internal valve changes, our company will promptly inform your company.

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-rate range: 0.016~6m³/h

Operating voltage: 2.8 to 5.5V;

Operating current ≤80mA

Opening time: ≤5S; Closing time: ≤5S

durability:Open/close times≥ 10,000 times;

working lifetime: 10years

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.
