Pneumatic high-pressure ball valve production

Pneumatic high-pressure ball valve

The pneumatic piston actuator adopts low friction materials, and the inner and outer surfaces of the cylinder body are treated with hard anodizing and anti-corrosion treatment, greatly improving the service life of the cylinder. Working principle: When the pneumatic actuator is connected to the circuit and system air source, air enters cylinder A (cylinder B) through pipe A or B, pushing the piston to move towards one end, thereby driving the rotating shaft and ball core to rotate 90 ° □ The top of the pneumatic actuator is linked with a visual sensor. When the green sign points to the "open" character, it indicates that the valve is open.

Pneumatic high-pressure ball valve

Using intelligent control and positioning, matched with an electrical valve positioner, the operation can be controlled by inputting 4-20mADC signals and 0.4-0.7MPa gas source, achieving adjustment of parameters such as pressure, flow rate, temperature, and liquid level. It is powered by compressed air, and the valve stem drives the valve core to rotate 90 degrees inside the valve body to achieve full open close action. This product is divided into metal seals and soft seals based on 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 situations where the medium is viscous, contains particles, and has fibrous properties. It can be widely used in automatic control systems for industries such as petroleum, chemical, teaching equipment, light industry, high-voltage equipment, pharmaceuticals, papermaking, etc., for remote centralized control or on-site control.
