The ZMIN-D51 NRS DIN3352 F5 Flanged Gate Valve is a high-performance industrial solution engineered to strict German standards. Featuring a Non-Rising Stem (NRS) design, this valve is specifically developed for applications where spatial constraints are a priority, ensuring a compact installation without sacrificing operational reliability. Whether utilizing metal or soft sealing, these valves provide a secure and durable shut-off mechanism for diverse fluid systems.
Designed in accordance with DIN 3352 for production and DIN 3202 for face-to-face dimensions (F5 length), the ZMIN-D51 offers superior structural integrity and flow control. The rotary mechanism allows the handwheel to drive the stem rotation for seamless opening and closing, making it an ideal choice for large diameter pipelines or underground installations where a rising stem would be impractical.
| Production Standard | DIN 3352 (German Standard) | Face-to-Face Length | DIN 3202 F5 (Extended Length) |
|---|---|---|---|
| Stem Design | NRS (Non-Rising Stem / Rotary) | Pressure Rating | PN10 / PN16 |
| Body Materials | CI / DI / WCB / Stainless Steel (SS) | Connection Type | Flanged End (DIN Standard) |
| Size Range | DN40 to DN600 | Sealing Options | Metal Sealing & Soft Sealing |
| Operation Mode | Handwheel Driven Rotation | Installation Suitability | Limited Space / Ground Installation |
Available in Ductile Iron, Cast Steel, and Stainless Steel to ensure maximum corrosion resistance and durability.
The Non-Rising Stem design allows for faster opening and closing cycles compared to traditional O.S.&Y valves.
Strict adherence to DIN 3352 and DIN 3202 ensures perfect compatibility with European piping systems.
Low overall height makes it the perfect fit for installations with limited overhead or underground clearance.
Every unit undergoes rigorous pressure testing before shipment to guarantee zero leakage in critical systems.
Ideal for water, oil, and gas transport across industrial manufacturing and infrastructure projects.
Optimized material sourcing for CI, DI, and WCB to balance cost and longevity.
Rigid adherence to German DIN standards for international interchangeability.
100% pressure testing protocol implemented for every single valve produced.
Advanced casting techniques to minimize porosity and ensure wall thickness stability.
Streamlined logistics for rapid delivery of large diameter industrial valves.
Expert guidance on selecting between F4 and F5 lengths based on site requirements.
| Comparison Metric | NRS Gate Valve (ZMIN-D51) | O.S.&Y. Gate Valve |
|---|---|---|
| Installation Space | Extremely Low / Compact | High / Requires Vertical Space |
| Overall Weight | Lighter / Efficient | Heavier / Bulkier |
| Opening Speed | Faster / Rotary Action | Slower / Linear Action |
| Underground Suitability | Highly Recommended | Not Recommended |
| Operational Height | Constant Height | Variable Height (Stem Rises) |
Gate valves are designed to either completely shut off the fluid flow or provide full flow in the open position. They are intended for on/off service rather than throttling.
NRS stands for Non-Rising Stem. The benefit is that the stem does not move upward when the valve opens, allowing for installation in tight spaces or underground where there is no room for a rising stem.
Both are German standards under DIN 3202, but the F5 structure length is longer than the F4 length. This affects the overall piping layout and valve spacing.
We provide several options depending on the medium and pressure: Cast Iron (CI), Ductile Iron (DI), Cast Carbon Steel (WCB), and Stainless Steel (SS).
Every single gate valve undergoes a rigorous pressure test before shipment to identify and eliminate any potential leakage issues, ensuring site reliability.
Yes, these valves are manufactured specifically to meet PN10 and PN16 pressure ratings and are compatible with corresponding DIN standard flanges.
