Threaded ball valves are quarter-turn shut-off valves with NPT or BSP threads, widely used for industrial on/off flow control.
Beyond Fluid is a stainless steel threaded ball valves manufacturer in China, supplying SS304 / SS316 valves to wholesalers, distributors, and OEMs.
SS304 / SS316 | NPT / BSPP / BSPT | 1/4″ – 4″ | up to 2000 WOG
A threaded ball valve is a quarter-turn shut-off valve with internal or external threads (such as NPT or BSP), designed for direct connection to piping systems without flanges or welding.
The valve opens or closes by rotating the handle 90 degrees, allowing or blocking flow through a precision-machined ball. Threaded ball valves are widely used in low to medium pressure systems where compact installation, easy maintenance, and reliable sealing are required.
Stainless steel threaded ball valves are commonly applied in water, oil & gas, HVAC, chemical, and general industrial pipelines, especially for smaller pipe sizes.
Feature:
1 piece ball valves is known for its low cost and Robust design that can be used in oil, gas and water applications.
2 piece ball valves is widely used for its quick, simple on/off control of liquid and gas flow.
3 PC ball valves design features a bolted body that can be easily disassembled for cleaning and maintenance.
3-way ball valve has three ports unlike the usual 2 way ball valves which only have two ports.
Mini ball valve is a compact, hand-operated valve designed to control fluid flow through pipelines.
A check valve is an automatic valve that allows fluid to flow in one direction, preventing backflow.

How to choose: Use NPT threaded ball valves for North America and most Middle East projects. Choose BSP threaded ball valves for Europe, UK, and regions following British pipe standards. Always confirm thread type before ordering to avoid leakage or installation issues.
Selecting the right threaded ball valve depends on material, valve structure, and port design. The guidelines below help ensure proper performance and long service life.
SS304 threaded ball valves are suitable for most general industrial applications, including water, air, and mild chemical systems. They offer good corrosion resistance at a lower cost.
SS316 threaded ball valves provide superior resistance to corrosion and chloride environments, making them ideal for chemical processing, marine, and Middle East applications.
Recommendation: Choose SS316 for aggressive media or outdoor installations; use SS304 for standard conditions.
2-piece threaded ball valves are the most common and cost-effective choice for standard on/off flow control. They are widely used in industrial piping where maintenance requirements are minimal.
3-piece threaded ball valves allow inline maintenance without removing the valve from the pipeline, making them ideal for systems requiring frequent cleaning or servicing.
Recommendation: Choose 2-piece for general use; select 3-piece for applications requiring easy maintenance.
Full port threaded ball valves provide minimal pressure drop and unrestricted flow, making them suitable for industrial systems where flow efficiency is critical.
Reduced port threaded ball valves offer a more economical solution for applications where slight flow restriction is acceptable.
Recommendation: Choose full port for high flow or process lines; select reduced port for cost-sensitive applications.
