This heavy-duty brass gate valve is designed for manual isolation of water and compatible non-corrosive liquid piping systems.
The valve features a brass body, Female × Female threaded ends and a handwheel-operated gate mechanism.
The current product specification includes 1/2″, 3/4″ and 1″ sizes with an ISO 228 / BSPP parallel thread.
The specified normal pressure is 1.6 MPa / 16 bar, with a working temperature range from -20°C to 150°C.

3. How Does a Brass Gate Valve Work?
A gate valve controls flow by moving an internal gate up or down through the flow path.
The handwheel is rotated to operate the stem and move the gate between the open and closed positions.
Rotating the handwheel operates the valve stem and moves the internal gate.
When the gate is raised, the flow path opens and fluid can pass through the valve.
When the handwheel is turned toward the closed position, the gate moves into the flow path.
In the fully closed position, the gate restricts flow through the pipeline.
4. What Is a Gate Valve Best Used For?
Gate valves are primarily used for fully open or fully closed isolation service.
They are generally selected where the valve needs to isolate a section of piping rather than continuously regulate flow.
Product selection should be based on the intended operating function and piping conditions.
5. Female × Female Threaded Ends
This model uses female threaded connections on both sides.
Both ends connect to compatible male-threaded pipes or fittings, providing a straightforward threaded installation in compatible piping systems.
Buyers should confirm both the nominal valve size and thread standard when ordering replacement valves or OEM products.
6. ISO 228 / BSPP Parallel Thread Connection
The current factory specification identifies the thread standard as ISO 228, commonly associated with BSPP or G parallel pipe threads.
Because the thread is parallel rather than tapered, the complete connection and sealing method should match the piping-system design.
BSPP, BSPT and NPT are different thread systems and should not be assumed to be interchangeable simply because the nominal pipe size is the same.
7. Confirmed Size Range
The currently available technical information confirms the following sizes:
| Nominal Size | Connection | Thread Standard |
|---|---|---|
| 1/2″ | Female × Female | ISO 228 / BSPP |
| 3/4″ | Female × Female | ISO 228 / BSPP |
| 1″ | Female × Female | ISO 228 / BSPP |
Only the sizes listed above are currently confirmed by the available technical information.
8. Working Pressure and Temperature
The current technical specification lists a normal pressure of:
1.6 MPa / 16 bar
The specified working temperature range is:
-20°C to 150°C
Actual suitability should also be evaluated according to the working medium and complete valve specification.
9. Working Media
The current technical information lists this brass gate valve for:
- Water
- Compatible non-corrosive liquids
10. Typical Applications
Threaded brass gate valves are commonly used as manual isolation valves in compatible water and general liquid piping systems.
Water Supply
Building Plumbing
Pipeline Isolation
General Liquid Systems
Final application suitability depends on the pressure, temperature, medium, material requirements and installation conditions.
11. What Does “Heavy-Duty” Mean for This Product?
This product is identified in the available factory information as a heavy-duty brass gate valve.
However, the current technical information does not provide comparative valve weight, body wall thickness or dimensional data against another gate-valve series.
12. What Should Buyers Confirm Before Ordering?
Before comparing gate valve quotations, buyers should confirm the complete product specification rather than comparing only appearance and unit price.
- Nominal valve size
- ISO 228 / BSPP thread requirement
- Normal and actual working pressure
- Working temperature
- Fluid medium
- Required brass specification
- Internal component requirements
- Valve dimensions or sample compatibility
- Logo and packaging requirements
- Order quantity

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

14. Frequently Asked Questions
What is this brass gate valve used for?
What sizes are currently confirmed?
What is the pressure rating?
What is the working temperature range?
What thread standard is used?
What media can this gate valve be used for?
Suitability for another medium should be confirmed according to the complete operating conditions.
What brass grade is used?
If a particular alloy is required, it should be specified before quotation.
What materials are used for the stem and gate?
These should be confirmed if they are important to the project specification.
Does heavy-duty mean the valve is heavier or thicker?
