Three-piece welded ball valve

Three-piece welded ball valves are designed for high-performance flow control in demanding applications. Their unique three-piece body design allows easy disassembly for maintenance or cleaning without removing the valve from the pipeline. Constructed with welded ends, these valves provide a secure, leak-free connection ideal for high-pressure and high-temperature environments. The internal ball rotates to control flow, offering reliable shutoff with low torque operation. These valves are commonly made from stainless or carbon steel, with full or reduced bore options. Suitable for manual or automated operation, three-piece welded ball valves are widely used in industries such as chemical processing, oil & gas, pharmaceuticals, food & beverage, and water treatment, where durability, easy serviceability, and compact design are critical.

Description

Product Description:

Three-piece welded ball valves are precision-engineered valves designed for reliable flow control in high-pressure and high-temperature environments. Featuring a three-piece body structure, these valves allow easy inline maintenance, cleaning, and replacement of internal components without dismantling the pipeline. The welded end connections ensure a strong, permanent, and leak-free seal, making them suitable for critical applications. With full or reduced bore options and compatibility with manual or automated actuation, these valves offer excellent versatility, durability, and operational efficiency.
