A 304/316 Stainless Steel 2-PC Female Thread Ball Valve is a quarter-turn shut-off valve designed to control the flow of liquids and gases in industrial piping systems. Manufactured from premium SS304 or SS316 stainless steel, this type of valve combines excellent corrosion resistance, high pressure capability, and long service life.
The valve consists of a two-piece body construction that allows easier maintenance and replacement compared to one-piece designs. Female threaded connections make installation simple and cost-effective, eliminating the need for welding in many applications.
As one of the most widely used industrial stainless steel ball valves, it is suitable for water treatment, oil and gas, chemical processing, food and beverage production, marine engineering, and HVAC systems.
Compared with one-piece or three-piece valves, a 2 piece ball valve offers an ideal balance between performance and cost.
Manufactured using investment casting technology, the valve body provides superior strength and dimensional accuracy.
The two-piece design allows easier inspection and servicing while maintaining excellent sealing performance.
Most full port stainless steel ball valves feature a bore diameter equal to the pipeline size, minimizing pressure loss and maximizing flow efficiency.
High-quality PTFE seats and seals ensure reliable shut-off performance and extended service life.
Choosing between a SS304 ball valve and a SS316 ball valve depends on the operating environment.
304 stainless steel contains approximately 18% chromium and 8% nickel.
Advantages include:
Typical Applications:
316 stainless steel contains molybdenum, which significantly improves corrosion resistance.
Advantages include:
Typical Applications:
For aggressive media and coastal environments, a 316 stainless steel ball valve is generally the preferred option.
