This PN16 brass ball valve features Female × Female threaded connections, a natural brass body and a blue lever handle for quarter-turn operation.
The valve is available from 1/2″ to 4″ with threads manufactured according to ISO 228.
The supplied technical specification states a normal pressure of 1.6 MPa and a working temperature range of -20°C to 120°C.
Working media listed in the catalogue include water, gas and oil.
Final suitability should still be evaluated against the actual pressure, temperature, medium and project requirements.
Specification Note:
ISO 228 specifies parallel pipe threads where the pressure-tight seal is not intended to be formed on the thread itself.
The mating connection and sealing arrangement should therefore be confirmed before installation.

ISO 228 Female Threaded Connections
Both ends of this brass ball valve use internal threaded connections manufactured according to ISO 228.
ISO 228 threads are parallel pipe threads commonly designated as G threads.
They should not be treated as identical to NPT or tapered BSPT connections simply because the nominal valve size is the same.
Buyer Note:
“1/2 inch,” “1 inch” or another nominal size alone is not enough to confirm thread compatibility.
The mating component should also match the required ISO 228 thread and sealing arrangement.

1.6 MPa Working Pressure
The supplied technical data specifies a normal pressure of 1.6 MPa.
This is commonly expressed as a PN16 pressure class in product descriptions.
However, pressure rating should not be evaluated independently from temperature, medium and the complete valve specification.
Pressure Selection:
Do not choose a valve only because the body looks heavier or because another similar model carries a higher pressure marking.
The required pressure class should match the actual piping-system specification.

Working Media and Temperature
The manufacturer’s technical specification lists the following working media:
Water is included in the stated working-medium range.
Gas is listed as an applicable working medium in the supplied catalogue specification.
Oil is also included in the manufacturer’s stated working-medium range.
The specified working temperature range is -20°C to 120°C.
Gas Application Note:
The catalogue lists gas as a working medium, but the supplied data does not state a specific gas approval or certification.
If certification is required by the destination market or project, confirm the applicable requirement separately.
Blue Lever Handle and Quarter-Turn Operation
The valve uses a blue lever handle for manual opening and closing.
A ball valve normally operates through approximately a quarter turn between its open and closed positions.
The long lever also provides a clear visual indication of valve position.
Before installation, sufficient clearance should be allowed for full handle movement, especially for the larger valve sizes.
What Should Buyers Confirm Before Ordering?
Confirm the required connection size from 1/2″ to 4″.
Verify that the mating connection matches the required parallel G-thread specification.
Check the system pressure against the specified 1.6 MPa pressure rating.
Confirm whether the application uses water, gas or oil and whether any additional material or certification requirements apply.
Confirm that the actual operating range remains within -20°C to 120°C.
If full-port or standard-port construction is important to the project, confirm the port design before ordering.
Quality Control Points
For a threaded brass ball valve, quality evaluation should include more than surface appearance.
- Brass body condition
- ISO 228 female thread dimensions
- Thread burrs and cleanliness
- Handle installation
- Ball opening and closing operation
- Internal component assembly
- Valve sealing performance
- Pressure testing according to the agreed specification
Practical QC Point:
Dimensional inspection and finished-valve testing serve different purposes.
Thread inspection confirms connection geometry, while leakage and pressure tests verify the performance of the complete assembled valve.

Frequently Asked Questions
What sizes are available?
The supplied catalogue lists 1/2″, 3/4″, 1″, 1-1/4″, 1-1/2″, 2″, 2-1/2″, 3″ and 4″ sizes.
What is the pressure rating?
The manufacturer’s technical data specifies a normal pressure of 1.6 MPa.
What thread standard does this ball valve use?
The catalogue specifies ISO 228 parallel pipe threads.
Is ISO 228 the same as NPT?
No. ISO 228 G threads are parallel pipe threads and differ from NPT in thread form and sealing concept.
The required mating connection should be confirmed before ordering.
What working media are listed for this valve?
The supplied technical specification lists water, gas and oil.
What is the working temperature?
The specified working temperature range is -20°C to 120°C.
Is this a full-port brass ball valve?
The supplied technical data does not identify the port design.
Full-port or standard-port construction should therefore be confirmed before publication or quotation if this parameter is important.
Can this valve be used for gas?
Gas is listed as a working medium in the supplied catalogue.
However, the provided information does not confirm a specific gas certification, so any market- or project-specific approval requirements should be checked separately.
