ATOS Atos proportional valve system is simple , Easy to connect , The price is low .ATOS The structure type of proportional valve is easy to control internal leakage , Until it drops to zero . therefore , Especially safe to use , Especially suitable for corrosive 、 Toxic or high and low temperature medium . Other automatic control valves usually extend beyond the stem , By electric 、 Pneumatic and hydraulic actuators control the rotation or movement of the valve core .

ATOS Working principle of ATOS proportional valve ：

The pressure adjustment of ATOS proportional valve is directly proportional to the input signal . External control gives 4~20mA The input signal to the electronic amplifier , After the electronic amplifier is processed, the proportional electromagnet is given C2, The proportional electromagnet pushes the conical valve core C5, Make it have an opening corresponding to the input signal , Thus, the corresponding pilot pressure is obtained . By controlling the main valve core A2 To regulate the pressure of the system . Equipped with pressure regulating valve , Limit the high voltage of the system . Equipped with internal pressure sensor C7, Detect the actual pressure value of the system , It can realize the closed-loop control of the pressure in the valve .

ATOS Installation and commissioning steps of ATOS proportional valve ：

1. In the installation ATOS Before the proportional valve , The cleanliness of the oil must reach NAS7 level .

2. Tighten the screws , Fix the proportional valve on the manifold block , And connect the cable .

3. Loosen the air vent screw at the end of one side of the electromagnet with a screwdriver .

4. The valve is available .
