One-Piece Body
One-piece ball valve configuration for manual on/off operation in a piping system.
Manual Ball Operation
Turning the handle rotates the stem and ball together to open or close the flow passage.
Threaded Connections
BSPT, BSPP and NPT thread types are listed; confirm the required size and version.
Material & Seat Options
The parts list includes WCB / CF8 / CF8M body materials and PTFE seat components.
OPERATING PRINCIPLE
How 1Pc Ball Valve Works
A simple turn controls the flow. Rotating the handle makes the valve stem and ball rotate together.
-
1. Turn the handle
The manual handle transfers the turning motion to the valve stem.
-
2. Rotate the ball
The stem drives the ball, changing the orientation of its flow passage.
-
3. Open or shut off
When the bore is aligned with the flow path, fluid passes through; turning it across the path closes the valve.

Frequently Asked Questions
Find answers to common questions about sizing, materials, threaded connections and operating conditions.
“What is a one-piece (1PC) ball valve?
A 1PC ball valve is a threaded ball valve featuring a solid, single-piece body. It is compact, lightweight, and cost-effective, making it widely used for on-off control in low-pressure pipelines.
What is the pressure rating?
1000 WOG (PN16); the working pressure can reach 16 bar at ambient temperature.
What is the operating temperature range?
PTFE (polytetrafluoroethylene) seat: 0°C ~” 120°C. Valve seats made of alternative materials are available if the temperature exceeds 120°C.
What media is it suitable for?
Water, compressed air, natural gas, oil, weak acids, and weak alkalis. Not suitable for highly corrosive media.
Is it full bore or reduced bore?
The standard two-piece ball valve features a full-bore design with low flow resistance.
Can it be used for steam?
If used for saturated steam, please provide the temperature and pressure specifications. PTFE seats are not suitable for high-temperature steam.
Is 100% pressure testing performed?
Yes. Every valve undergoes an airtightness test before packaging.
What is the Minimum Order Quantity (MOQ)?
The MOQ is low, and mixed-batch orders (different sizes in a single order) are supported.
How are the valves packaged?
Each valve is placed in a plastic bag, then a small box, and finally an outer carton. Wooden pallets are available as an option.
Can I apply my own logo or custom labels?
Yes, OEM and ODM services are supported. Logos can be printed on the handle or the valve body.
Does it provide bidirectional sealing?
Yes, it utilizes a floating ball design that supports bidirectional sealing.
Can the valve be installed vertically or horizontally?
Both horizontal and vertical installations are possible. The handle position can be adjusted.
What is the warranty period?
A 12-month warranty is provided against manufacturing defects. Damage caused by improper operation is not covered.
How can leakage be prevented?
Do not overtighten the threads during installation, and avoid impacts. Regular inspections are recommended for long-term use.
What sizes are available?
Standard product specifications cover 1/2 inch to 2 inches (DN15–DN50). The accompanying size chart currently covers the DN15–DN50 range; please verify the specific parameters for the size you require.
Are BSPT, BSPP, and NPT connection types available?
Standard stock includes BSPT connections; however, the original specification sheet lists BSPT, BSPP, and NPT options. Thread options: Please specify the thread standard and nominal size when inquiring so we can confirm availability.
What are the temperature and pressure limits?
Standard specifications indicate a working pressure of 1.6 MPa and an operating temperature range of 0°C to 120°C. Suitability for specific fluids and temperatures requires separate confirmation.
Can this valve be used for throttling?
The accompanying operating instructions advise against keeping the valve in a partially open position for extended periods, as high-velocity fluid flow may erode the PTFE (polytetrafluoroethylene) seat.
What is the lead time for orders?
For standard orders, we maintain a stock of 5,000 valves with BSPT connections; other thread types require custom production, with a manufacturing capacity of 50,000 units within 15 days.
What is the product quality like? Is there a warranty?
Each valve undergoes rigorous quality inspection (including checks on materials, threads, seals, and the valve body) and comes with a one-year warranty covering normal operating conditions.
