Welded three-piece pneumatic ball valve

1. Overview of the three-piece welded pneumatic ball valve : The
pneumatic three-piece internal threaded ball valve is composed of a double (single) acting pneumatic piston actuator and an internal threaded ball valve. The valve body can be divided into integral type, two-stage type and three-stage type. The valve seat adopts an elastic sealing structure, which is reliable in sealing and easy to open and close. The valve stem adopts a bottom-mounted structure with an inverted seal. When the valve cavity is abnormally increased in pressure, the valve stem will not be impacted. The pneumatic piston actuator adopts low-friction materials to make the bearing sleeve, and the inner and outer surfaces of the cylinder are treated with hard anodized anti-corrosion treatment, which greatly improves the service life of the cylinder. This product has stable performance and is widely used in petrochemical, metallurgical, electric power and other industrial sectors.
