Pneumatic valve action

After understanding the working principle, classification and characteristics of pneumatic valves, what is the function of pneumatic valves? Next, Bian Xiao will specifically introduce the function of pneumatic valve and the related contents of matters needing attention in the use of pneumatic valve.

Pneumatic valve function:

1, realize proportional adjustment.

The purpose and characteristic of pneumatic valve is right-angle rotating structure, which can be used in conjunction with valve positioner to realize proportional adjustment.

2. Small size and sensitive adjustment.

V-shaped valve core is suitable for various adjustment occasions, with large rated flow coefficient, large adjustable ratio, good sealing effect, sensitive adjustment performance and small volume, and can be installed vertically and horizontally.

3. Controlled substances

Suitable for controlling gas, steam, liquid and other media.

Matters needing attention in the use of pneumatic control valve:

1. The valve should be stored in a dry room, and both ends of the channel must be closed. Stacking and storage are not allowed.

2. The regulating valve stored for a long time should be inspected regularly to remove dirt, and the moving parts and machined surfaces should be coated with antirust oil to prevent rusting.

3. This valve should be installed on the horizontal pipeline and must be installed vertically. The valve stem is up.

4. Installation must be carried out according to the flow direction of the medium shown by the arrow in the figure.

By introducing the function, working principle, classification and characteristics of pneumatic control valve, do you know more about pneumatic control valve?
