The ZHMSS-D1 DIN 3202 Swing Type Check Valve is a premium industrial solution engineered for critical fluid control. Specifically designed for high-demand environments such as chemical processing and food production, this flanged-end valve ensures reliable unidirectional flow, effectively preventing backflow to protect upstream equipment and maintain system integrity.
Constructed from high-grade stainless steel, the ZHMSS-D1 offers exceptional resistance to corrosion and rust, making it ideal for sterile and aggressive media. By adhering to the DIN 3202 standard for face-to-face length, it guarantees seamless integration into standardized European piping systems, combining durability with high-temperature stability for long-term operational efficiency.
| Standard | DIN 3202 (Face-to-Face) | Connection Type | Flanged End |
|---|---|---|---|
| Pressure Rating | PN10 / PN16 | Available Materials | CI / DI / WCB / Stainless Steel |
| Size Range | DN50 to DN300 | Flow Direction | Single Flow (Unidirectional) |
| Application | Chemical, Food, Industrial | Installation | Horizontal or Vertical Pipes |
| Design Feature | Swing Type Disc | Key Advantage | Anti-corrosion & Anti-rust |
Stainless steel construction prevents oxidation and rust, ensuring longevity in caustic chemical environments.
Built for high reliability and durability, reducing maintenance downtime and total cost of ownership.
The unobstructed flow channel minimizes fluid resistance and pressure drops across the system.
The swing disc closes quickly with minimal impact force, preventing water hammer effects.
Engineered for flexibility, suitable for both vertical and horizontal piping configurations.
High-sensitivity action ensures a tight seal to eliminate backflow leakage completely.
Real-time monitoring of DIN 3202 valve stock levels to ensure rapid delivery.
Rigorous pressure testing for PN10/PN16 ratings to ensure zero leakage.
Scheduled inspection tracking for industrial valve replacement cycles.
Ensuring all stainless steel valves meet strict international industrial standards.
Streamlined shipping for heavy flanged valves to reduce transit lead times.
Technical support for tailoring valve materials to specific corrosive media.
| Feature | DIN 3202 Swing Valve | Standard Check Valve |
|---|---|---|
| Corrosion Life | Ultra-High (Stainless Steel) | Moderate (Cast Iron) |
| Pressure Stability | Excellent (PN10/PN16) | Standard |
| Flow Efficiency | High (Low Resistance) | Average |
| Installation Cost | Moderate (Standardized) | Low |
| Maintenance ROI | High (Long Intervals) | Low (Frequent) |
No. A check valve is designed only to prevent the backflow of the medium; it does not actively restrict the forward flow unless it is improperly sized or obstructed.
Its key advantages include a fast-closing disc with low impact force, compatibility with both horizontal and vertical pipes, minimal fluid resistance, and high sealing reliability.
The main differences lie in the standard face-to-face dimensions (DIN 3202 vs JIS) and pressure ratings (PN10/PN16 for DIN vs 5K/10K/16K for JIS), making them compatible with different regional piping systems.
Stainless steel provides critical anti-corrosion, anti-rust, and high-temperature properties essential for food and chemical industries, justifying the higher material and manufacturing costs.
Depending on the application, these valves can be manufactured from Cast Iron (CI), Ductile Iron (DI), Carbon Steel (WCB), or Stainless Steel (SS).
The valve features a flanged end connection, meaning it is securely fixed to the piping system using high-strength bolts and gaskets to ensure a leak-proof seal.
