Import Ball Valves — Buy in Bulk from Supplier in China

These ball valves are engineered for industrial flow control in pipelines carrying water, gas, or oil. Constructed from gray cast iron or ductile iron, they provide durability and resistance to corrosion and wear in demanding environments. The design ensures a tight seal with minimal torque, reducing operational stress and extending service life. The valves are suitable for both on-off and throttling applications, depending on the seat material and pressure class.

Gray cast iron (ASTM A126 Class B) is standard for low-pressure applications, while ductile iron (ASTM A395) is used for higher pressure and temperature ranges. Typical industry specifications include a pressure rating of PN10 to PN25 for gray iron and PN16 to PN40 for ductile iron, with temperature limits up to 200°C for standard seats. The valves comply with design standards such as API 608, ISO 17292, or BS 5351, depending on the model and intended use.

These valves are used in oil and gas, water treatment, chemical processing, and manufacturing industries. Buyers should confirm the material grade, pressure class, and end connections (flanged, threaded, or socket-weld) to match their pipeline specifications. The supplier’s catalog includes options for soft-seated (PTFE or reinforced PTFE) and metal-seated designs, each offering different leak tightness and temperature capabilities. MOQ and lead times are subject to confirmation with the supplier.
