Product Description

Premium German Standard Cast Iron Wafer Butterfly Valve for Reliable Performance

The German Standard Cast Iron Wafer Butterfly Valve, designed for efficient flow control, features a compact and lightweight structure with a durable cast iron body (QT450/GGG50) and corrosion-resistant stainless steel disc (SS304/SS316). Compliant with DIN standards, it ensures reliable performance in industrial applications.

Specification

Key Features:

1.Robust Construction: The valve body is made of high-grade cast iron, while the disc and stem utilize stainless steel for enhanced durability and resistance to wear.

2.Versatile Sealing: Equipped with NBR or PTFE seals, it provides zero leakage and adapts to temperatures ranging from -20°C to 150°C, suitable for water, oil, gas, and mildly abrasive media.

3.Quick Operation: The wafer design allows for fast installation and 90° reciprocating rotation, enabling rapid shut-off and minimal pressure drop.

4.Broad Compatibility: Complies with DIN/EN standards for flange connections (ISO 5211 top flange) and pressure ratings up to PN16.

Technical Specifications:

1.Size Range: DN50–DN300 (2"–12").
2.Pressure Rating: PN10–PN16
3.Standards: DIN 3354, EN 593 (design and testing).
4.Applications: Ideal for HVAC, water treatment, chemical processing, and industrial pipelines.

Advantages:

1.Low maintenance with a long service life due to anti-corrosion coatings and double-eccentric sealing technology .
2.Cost-effective and recyclable, aligning with sustainable engineering practices .
