Product Description

DIN Standard Flanged Swing Cast Iron Check Valve

The German Standard Cast Iron Flanged Swing Check Valve ensures reliable one-way flow control in piping systems. Designed with a robust cast iron body (GG25/EN-JS) and DIN-compliant flanges, it prevents backflow efficiently while minimizing pressure loss. Ideal for water, wastewater, and non-corrosive industrial media.

Specification

Key Features:

1.Durable Construction: High-grade cast iron body with epoxy-coated surfaces or corrosion resistance.
2.Swing Disc Design: Hinged disc automatically opens with forward flow and closes via gravity/seal pressure, ensuring swift shut-off.
3.Flanged Connection: Complies with DIN EN 1092-1 (PN10/16) for easy integration into pipelines.
4.Zero Maintenance: Self-acting operation with no external controls required.
5.Versatile Sealing: Optional NBR, EPDM,seals for compatibility with temperatures from -10°C to +120°C.

Technical Specifications:

1.Size Range: DN50–DN600 (2"–24")
2.Pressure Rating: PN10/16
3.Standards: DIN 3840 (design), EN 1092-1 (flanges)
4.Installation: Horizontal or vertical (flow-upward orientation).

Applications:

Suitable for water supply, HVAC systems, drainage networks, and general industrial pipelines.

Advantages:

1.Low turbulence design extends service life and reduces wear.
2.Cost-effective solution with DIN-certified quality for long-term reliability.
