The ZRIN-D51 NRS DIN3352 F4 Flanged Gate Valve is a high-precision industrial valve engineered according to German production standards. Specifically designed for efficient fluid control, it features a Non-Rising Stem (NRS) architecture, which ensures that the stem does not extend upward during operation, making it an ideal choice for installations with limited overhead space or where protection against stem damage is critical.
Built to comply with the DIN 3352 and DIN 3202 F4 standards, this valve provides a compact face-to-face structure compared to F5 models. Whether you require metal sealing or soft sealing options, the ZRIN-D51 offers exceptional reliability for shut-off applications in industrial piping systems, combining durability with the precision of German engineering to ensure leak-proof performance.
| Production Standard | DIN 3352 (German Standard) | Structure Length | DIN 3202 F4 (Compact Design) |
|---|---|---|---|
| Stem Type | NRS (Non-Rising Stem / Rotary) | Pressure Rating | PN10 / PN16 |
| Body Material | CI / DI / WCB / Stainless Steel | Flange Drilling | According to DIN 2501 |
| Size Range | DN40 to DN300 | Connection Type | Flanged End |
| Drive Method | Handwheel Rotation | Sealing Options | Metal Seated / Soft Seated |
The Non-Rising Stem (NRS) design eliminates vertical stem movement, allowing for installation in confined spaces.
Utilizing the F4 structure length, this valve is shorter than F5 models, reducing the overall piping footprint.
Manufactured strictly under DIN 3352 standards to ensure global compatibility and high-performance sealing.
Available in Cast Iron, Ductile Iron, WCB, and Stainless Steel to suit various environmental requirements.
The rotary handwheel drive allows for smooth opening and closing cycles with minimal effort.
Full alignment with DIN 2501 flange drilling makes replacement and integration seamless.
Real-time tracking of valve sizes from DN40 to DN300 to ensure rapid delivery.
Strict adherence to DIN production standards with rigorous pressure testing.
Expert guidance on choosing between F4 and F5 lengths for your specific layout.
Tailored material selection (CI/DI/SS) to meet specific corrosive medium needs.
Global shipping solutions for heavy industrial valve components.
One-year standard warranty and maintenance support for long-term operation.
| Feature | NRS DIN3352 F4 Valve | Standard Gate Valve |
|---|---|---|
| Installation Space | Ultra-Compact (NRS/F4) | Requires Vertical Clearance |
| Operational Safety | High (Stem Protected) | Moderate (Exposed Stem) |
| Maintenance Cost | Low (Reduced Wear) | Standard |
| Standardization | DIN 3352 / 3202 | Various/Generic |
| Lead Time ROI | Fast Integration | Standard Integration |
Ball valves offer tighter seals, higher reliability, and faster operation, but are generally more expensive. Gate valves are preferred for full-bore flow and specific industrial standards. Note that ball valves can cause water hammer due to rapid closing.
F4 and F5 refer to face-to-face dimensions under the DIN 3202 standard. The F4 structure length is shorter than the F5, providing a more compact footprint for piping installations.
NRS stands for Non-Rising Stem. In these valves, the stem rotates but does not move up or down during the opening and closing process, which is essential for space-constrained environments.
The ZRIN-D51 series is available in Cast Iron (CI), Ductile Iron (DI), Carbon Steel (WCB), and Stainless Steel (SS) to accommodate different pressure and corrosion requirements.
These specific NRS DIN3352 F4 valves are rated for PN10/16. They require fire protection at high temperatures and are generally not recommended for extremely high-pressure or highly corrosive medium environments without specific material upgrades.
Generally, the standard warranty period for our gate valves is one year from the date of purchase or installation.
