Brief description of pneumatic high pressure ball valve

Pneumatic high pressure ball valve adopts intelligent control and positioning, which is matched with the electrical valve positioner. The 4-20madc signal and the air source of 0.4~ 0.7mpa can be input to control the operation, realizing the adjustment of pressure, flow, temperature, liquid level and other parameters. It is powered by compressed air, and the stem drives the spool to rotate 90° in the valve body to achieve a fully open - fully closed action.

The product is divided into metal seal and soft seal according to its sealing performance. It has the advantages of compact structure, small volume, reliable operation, good sealing, easy maintenance, convenient installation and strong adaptability. Especially suitable for the medium is viscous, containing particles, fiber properties of the occasion. Can be widely used in petroleum, chemical industry, teaching equipment, light industry, high pressure equipment, pharmaceutical, papermaking and other industrial automatic control systems, remote centralized control or local control.
