JOEPAI High Quality One Piece Stainless Steel Internal Thread Hexagon Ball Valves get their name from the six-sided body. That shape is not just for looks — it lets you get a standard wrench on the valve during installation, which matters when you are working in a tight spot and do not have much room to move.
These are made as one-piece threaded ball valves, so there is no separate end cap to worry about. They are mostly used for on-off control on small-bore lines, and they tend to show up in places where space is tight and a full-size valve simply will not fit.
The design itself is simple, with few parts to fail. That is a big part of why they hold up well over time and why so many industrial fluid systems use them as a go-to choice for small line shut-off.

Applications & Installation Notes
The One Piece Stainless Steel Internal Thread Hexagon Ball Valves are widely used for on/off control on small-bore lines in water, gas, oil and other industrial fluid systems, especially where installation space is tight.
Typical Applications
Small-bore industrial fluid lines
Instrumentation and control panels
Water, gas and oil on/off control
Compressed air and pneumatic systems
Food and chemical processing equipment
Installation & Maintenance
Use a wrench on the hex body — never on the pipe or fitting.
Not recommended for throttling; use for on/off control only.
Ensure thread sealant or tape is applied correctly to avoid leakage.
Leave space for the handle to rotate freely.
Inspect the stem seal periodically for long service life.

FAQs
What is a hexagonal ball valve?
One Piece Stainless Steel Internal Thread Hexagon Ball Valve is a one-piece threaded ball valve with a hex-shaped body. The hex profile lets you clamp the valve directly with a wrench during installation, so you do not need extra wrench lugs on the body. That makes it a good fit for small bore pipelines where space is tight.
What thread types are available?
We offer NPT, BSPT, BSPP(G) internal threads. Tell us the standard and we will process accordingly. Other thread standards can be customized on request.
What pressure can the hexagonal ball valve withstand?
Standard rating is 1000PSI (PN64), and the high pressure version can withstand up to 2000PSI (137bar). Please confirm the exact rating you need before ordering.
Is it full port or reduced port?
The hexagonal one-piece stainless steel ball valve comes with a reduced port as standard. If you need a different port configuration, please contact us to discuss availability.
What temperature range does this valve support?
With PTFE seat, the working temperature is below 150°C. With PPL seat, the working temperature can go up to 300°C. Please choose the seat material based on your actual working temperature.
Can I get a sample before placing a bulk order?
Yes. We support sample orders for quality evaluation. Please contact us with your required size, thread standard, pressure rating and medium, and our team will arrange the sample and delivery details quickly.
What is the MOQ and delivery time?
We offer flexible MOQ for trial orders and long-term cooperation. Normal delivery time is about 15–30 days after order confirmation, depending on quantity and customization requirements.
