How to adjust the pneumatic automatic valve GYD20- 16B of air compressor?

The two straight screws in the figure below are used to adjust the pressure. One is to adjust the upper pressure limit, which is used to adjust the pressure difference between the upper and lower limits.

Because these small micro-components can be used under the pressure of 0.2~0.7MPa, they can be integrated into the existing standard pneumatic system. If the piston area of the small cylinder is small and the corresponding power is small, then the small valve will be very different. Under the same flow rate, the new small valve has a more compact structure and a smaller interface size.

For example, the reversing control of the same flow rate is relatively boring, and its volume is only 7% of the past (1997 and 196 1 year). It is the inevitable trend of the development of pneumatic components that the size is constantly miniaturized and the function is constantly strengthened. Despite the limited size, the design of pneumatic components has been further improved.

The function is constantly enhanced and the volume is constantly shrinking;

Miniaturized pneumatic components such as cylinders, valves and modules are being applied in many industrial fields. Micro-pneumatics are not only used in precision machining (such as watch manufacturing), electronic industry (such as printed circuit board production) and module assembly, but also in pharmaceutical industry, medical technology, food processing and packaging technology.

In these fields, a cylinder with a piston diameter as small as 2.5 mm (or a rectangular piston with a width of 1.6 mm), a gas valve with a width of 10 mm (a valve with a width of 5 RNN will be introduced soon) and related auxiliary components, such as gas path plates, gas path distributors, M3 threaded micro-components and many other micro-pneumatic components, have become serial products.
