This PN16 non-rising stem bronze gate valve is designed for manual pipeline isolation using a compact non-rising stem structure.
The current technical specification confirms a bronze body, bronze bonnet and bronze gate, together with a brass stem and PTFE sealing components.
The valve is rated at 1.6 MPa / 16 bar non-shock, with a working temperature range from -20°C to 120°C.
The available technical drawing lists connection sizes of Ø22, Ø28 and Ø54 mm.

3. What Is a Non-Rising Stem Gate Valve?
In a non-rising stem gate valve, the stem does not extend significantly upward as the valve is opened.
Instead, rotation of the handwheel operates the internal stem-and-gate mechanism while keeping the external valve height relatively compact.
This structure can be useful where available installation height is limited compared with a rising-stem valve.
4. How Does the Gate Valve Work?
Turn the Handwheel
Rotating the handwheel operates the brass stem and moves the internal bronze gate.
Gate Opens
As the gate moves away from the flow path, the passage through the valve opens.
Gate Closes
Rotating the handwheel in the opposite direction moves the gate back into the flow path.
Pipeline Is Isolated
In the fully closed position, the gate restricts flow through the valve.

6. Dimensions
The current technical drawing lists three connection sizes.
Dimensions are shown in millimeters.
| D | D1 | L | L1 | H |
|---|---|---|---|---|
| Ø22 | Ø19.05 | 57 | 16 | 86.5 |
| Ø28 | Ø25 | 63 | 19 | 96 |
| Ø54 | Ø50 | 98 | 33 | 153 |
Dimensions are based on the currently available technical drawing. Final connection compatibility should be confirmed before ordering.
7. Pressure and Testing
The valve is specified for a normal non-shock pressure of:
1.6 MPa / 16 bar
The current technical information also lists:
- Shell test: 2.4 MPa hydrostatic
- Seat test: 1.76 MPa hydrostatic
- Air test: 8 bar
Test requirements for an OEM or project order should be confirmed according to the agreed specification before production.
8. Working Temperature
The current technical specification lists a working temperature range of:
-20°C to 120°C
Actual suitability also depends on the working medium, pressure and complete material configuration.
9. Lead-Free Bronze Option
The current factory information states that lead-free bronze materials are available.
Lead-free material availability alone should not be treated as proof of a particular drinking-water certification.
10. Connection Selection
The current technical drawing provides connection dimensions of Ø22, Ø28 and Ø54 mm, but the available source information contains conflicting descriptions of the actual connection type.
For this reason, buyers should confirm the connection method before ordering.
For replacement projects, useful information includes:
- Existing valve photos
- Pipe outside diameter
- Connection dimensions
- Technical drawing
- Physical sample
11. What Should Buyers Confirm Before Ordering?
- Required connection size
- Actual connection type
- Working pressure
- Working temperature
- Working medium
- Standard or lead-free bronze requirement
- Required dimensions
- Testing requirement
- Logo and marking
- Packaging requirement
- Order quantity
