First, the performance and application of pneumatic ball valve

       Pneumatic ball valve is one of the most common angle-throttling pneumatic valves. The air source pressure pushes the piston to drive the valve stem to do a ≤ 120 ° rotation to achieve the valve switching, commutation or adjustment. It has many advantages such as sensitive movement and good sealing performance. Is widely used in petroleum refining, long-distance pipelines, chemicals, paper, food, pharmaceuticals, water conservancy, electricity, municipal, chemical and other industries.

Second, the main characteristics and types of pneumatic ball valve

       Pneumatic ball valves are mainly divided into: floating pneumatic ball valve, fixed pneumatic ball valve, switch-type pneumatic ball valve, reversing pneumatic ball valve, adjustable pneumatic ball valve, O -type pneumatic ball valve, V -type pneumatic ball valve, pneumatic ball valve, pneumatic flange ball valve , pneumatic screw ball valve, pneumatic welding ball valve, pneumatic quick ball valve, pneumatic stainless steel ball valve, pneumatic gas ball valve, sanitary pneumatic ball valve, single acting pneumatic ball valve, double action pneumatic ball valve ...

Pneumatic ball valve is the valve with the least fluid resistance in all valves, equivalent to a straight pipe of the same diameter when fully opened;

Small installation space, symmetrical structure and beautiful appearance;

Sealing performance is good, and the valve stem does not have a long service life.

Suitable for most media, water, oil, gas, steam, slurry, etc.
