¤ Precision Control valve

●Features: 

Precision Control valve applied with micro pump ,it is adjust the delicate, wide regulating range,
convenient installation,easy to use.It is connected with different lines, which can adjust the flow rate,
the vacuum degree and the output pressure.

●Working principle: 

By adjusting the knob to change the valve opening degree, to achieve the pressure and flow regulation.

●Technical Specification:

Model

AS2002F

Maximum Drift diameter

≈Ф2mm

Working pressure

<0.2MPa

Radius of mounting hole

≈Ф3.2mm

Working medium

Gas

 Medium gas temperature

-5℃ ~ 60 ℃(Unfrozen )

Main materials  of valve

Brass and PBT

●Warming:

1.Maintenance : the valve should be used in a dry and ventilated environment and maintain
the cleanliness of the threaded parts.

2.Valve adjustment to the limit of the full open and full closed position, the force should
not be too large to avoid damage to the spool.

3.When the joint is changed, the movable ring must be pushed to the direction of valve body.

4.Do not frequently plug and swivel joints, otherwise it will damage the control valve!
