This 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 connections and a handwheel-operated gate mechanism. The current technical specification identifies the thread standard as ISO 228 parallel pipe thread, commonly described in the market as BSPP / G thread.
Available sizes range from 1/2″ to 2″, with a normal pressure rating of 1.6 MPa / 16 bar and a working temperature range from -20°C to 150°C.

The currently available technical information does not specify the brass alloy grade, stem material, gate material, packing material or detailed internal construction. These parameters should be confirmed if they are required for a specific project.
3. How Does a Brass Gate Valve Work?
A gate valve controls flow by moving an internal gate vertically through the flow passage.
Rotating the handwheel operates the stem and moves the internal gate.
As the gate moves away from the flow passage, the valve opens and allows the medium to pass through.
Turning the handwheel in the opposite direction moves the gate back into the flow path.
In the fully closed position, the gate restricts flow through the valve.
4. Gate Valve for Isolation Service
Gate valves are primarily selected for fully open or fully closed isolation service.
When fully open, the gate is moved away from the main flow path. When fully closed, it isolates the downstream section of the piping system.
5. Female × Female Threaded Ends
This model uses female threaded connections on both ends.
Both connections are designed to mate with compatible male-threaded piping or fittings.
For replacement and OEM orders, both nominal size and thread standard should be confirmed rather than specifying only the valve size.
6. ISO 228 / BSPP Parallel Thread
The current factory specification identifies the thread standard as ISO 228.
ISO 228 specifies parallel pipe threads used for mechanical assembly of valves, fittings and related piping components.
In international valve and plumbing markets, this connection is commonly referred to as a BSPP or G parallel thread.
ISO 228 parallel threads should not be confused with BSPT or NPT tapered pipe threads. Always confirm the exact connection standard before purchasing replacement valves.
7. Available Sizes
The current technical specification confirms the following nominal valve 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 |
| 1-1/4″ | Female × Female | ISO 228 / BSPP |
| 1-1/2″ | Female × Female | ISO 228 / BSPP |
| 2″ | Female × Female | ISO 228 / BSPP |
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
Final valve selection should consider pressure, temperature and working medium together rather than evaluating pressure rating alone.
9. Working Media
The current technical information identifies the valve for:
- Water
- Compatible non-corrosive liquids
10. Typical Applications
Female-threaded brass gate valves are commonly selected for manual isolation in compatible water and general liquid piping systems.
Water Supply
Building Plumbing
Pipeline Isolation
General Liquid Systems
11. Installation Considerations
Before installation, confirm:
- Correct nominal valve size
- ISO 228 / BSPP thread compatibility
- Working pressure
- Working temperature
- Fluid compatibility
- Required sealing method for the threaded connection
- Adequate space for handwheel operation
Piping should be correctly aligned during installation to avoid unnecessary mechanical stress on the valve body.
12. What Should Buyers Confirm Before Ordering?
Brass gate valves with similar external appearance can still have different materials and internal specifications.
Before comparing quotations, confirm:
- Valve size
- ISO 228 / BSPP thread requirement
- 1.6 MPa working requirement
- Working temperature
- Working medium
- Required brass alloy, if specified
- Internal component requirements
- Valve dimensions
- Logo and body marking
- 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 requirements
