This brass male × female ball valve combines an external male threaded connection on one side with an internal female threaded connection on the other.
The valve uses ISO 228 / BSPP parallel pipe threads and a blue lever handle for manual quarter-turn shut-off operation.
The current product specification includes 1/2″, 3/4″ and 1″ sizes, with a normal pressure rating of 1.6 MPa / 16 bar and a working temperature range from -20°C to 120°C.
The technical specification lists water, gas and oil as working media. For gas or other application-specific projects, actual medium, pressure, temperature and applicable market requirements should be confirmed before ordering.

The available technical information does not confirm the brass alloy grade, ball material, stem material or seat material. If these parameters are required for your project, they should be confirmed before quotation and production.
3. Male × Female Threaded Connection
The main difference between this valve and a conventional Female × Female ball valve is its mixed connection configuration.
Male Thread End
The external threaded end connects directly to a compatible female-threaded pipe, fitting or component.
Female Thread End
The internal threaded end connects to a compatible male-threaded pipe, fitting or component.
This configuration can reduce the need for an additional male-to-female adapter where the piping layout already requires different connection types at each side of the valve.
4. ISO 228 / BSPP Parallel Thread
The current technical specification identifies the connection as ISO 228 parallel pipe thread, commonly referred to as BSPP or G thread.
ISO 228 threads are parallel rather than tapered.
The complete sealing method should therefore match the design of the connected pipe or fitting.
BSPP, BSPT and NPT are different thread systems. Do not select a replacement valve based only on nominal size such as 1/2″ or 3/4″. Confirm the actual thread standard before ordering.
5. Confirmed Available Sizes
The currently available factory technical information confirms the following sizes:
| Nominal Size | Connection | Thread Standard |
|---|---|---|
| 1/2″ | Male × Female | ISO 228 / BSPP |
| 3/4″ | Male × Female | ISO 228 / BSPP |
| 1″ | Male × Female | ISO 228 / BSPP |
Only the sizes listed above are currently confirmed by the available technical specification.
6. Working Pressure and Temperature
The current product specification lists a normal pressure rating of:
1.6 MPa / 16 bar
The specified working temperature range is:
-20°C to 120°C
Product suitability should be evaluated using the actual working pressure, temperature and medium rather than pressure rating alone.
7. Working Media
The current technical specification lists the following working media:
- Water
- Gas
- Oil
The term “gas” in the technical specification does not by itself confirm suitability for every fuel-gas application or certification requirement. For gas projects, provide the exact gas medium, pressure, temperature and destination-market requirements before ordering.
8. How Does the Brass Ball Valve Work?
A ball valve controls flow by rotating an internal ball through approximately 90 degrees.
Open Position
When the bore in the internal ball is aligned with the pipeline, the medium can pass through the valve.
Turn the Lever
Rotating the blue lever handle turns the valve stem and internal ball.
Closed Position
After approximately a quarter turn, the solid side of the ball blocks the flow path and isolates the pipeline.
9. When Is a Male × Female Ball Valve Useful?
A mixed-thread ball valve can be useful when a piping system requires a male connection at one side and a female connection at the other.
Compared with installing a Female × Female valve together with an additional threaded adapter, a Male × Female configuration may provide a more direct connection where the dimensions and thread requirements match.
Typical selection situations include:
- Connecting piping components with different male and female ends
- Replacement of an existing Male × Female valve
- Compact threaded piping assemblies
- OEM equipment requiring a mixed-thread valve configuration
10. Installation Considerations
Before installing the valve, confirm:
- Correct nominal valve size
- ISO 228 / BSPP thread compatibility
- Correct Male × Female connection orientation
- Working pressure
- Working temperature
- Medium compatibility
- Adequate space for lever operation
Threaded piping should be properly aligned during installation to avoid placing unnecessary mechanical stress on the valve body.
11. What Should Buyers Confirm Before Ordering?
Two brass ball valves that appear similar may have different materials, internal structures and technical specifications.
Before requesting or comparing quotations, confirm:
- 1/2″, 3/4″ or 1″ valve size
- Male × Female connection
- ISO 228 / BSPP thread requirement
- 1.6 MPa working requirement
- Actual working medium
- Working temperature
- Required brass alloy if specified
- Required internal component materials if specified
- Logo and marking requirements
- Packaging requirements
- Order quantity

12. OEM and Custom Brass Ball Valve Options
SUNRICH FLOW supports OEM and customized brass valve projects for importers, distributors and private-label customers.
Depending on the project, customization can be evaluated based on:
- Technical drawings
- Physical valve samples
- Required dimensions
- Thread requirements
- Material specifications
- Valve body marking
- Logo
- Handle requirements
- Private-label packaging
If you do not have a technical drawing, an existing physical sample can also be used as the starting point for technical evaluation.
