First, Three-piece welded pneumatic ball valve overview:
The three-piece welded ball valve consists of a double (single) acting pneumatic piston actuator and a welded ball valve. The valve body can be divided into integral type, two-stage type and three-stage type. The valve seat adopts elastic sealing structure, which is reliable in sealing and easy to open and close. The valve stem adopts a bottom-loading structure with an inverted seal, and the valve stem is not impacted when the valve cavity is abnormally boosted. The pneumatic piston actuator is made of low friction material and is made of bearing sleeve. The inner and outer surfaces of the cylinder are hard anodized and anticorrosive, 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.
