Product Description

DIN standard cast iron soft sealing wafer butterfly valve

The German Standard Cast Iron Soft-Seal Wafer Butterfly Valve combines a robust cast iron body (GG25/EN-JS) with advanced soft-seal technology for leak-proof performance. Compliant with DIN/EN standards, it ensures reliable shut-off and flow control in water, air, and mild chemical applications.

Specification

Key Features:

1.Soft-Seal Design: EPDM, NBR, or PTFE-lined disc provides zero leakage, even under low-pressure conditions.
2.Compact & Lightweight: Wafer-style construction simplifies installation and reduces system load.
3.Corrosion Resistance: Epoxy-coated cast iron body with stainless steel stem (SS304/SS316) for durability.
4.90° Operation: Quick quarter-turn handle, gear, or actuator control for efficient flow adjustment.
5.DIN Compliance: Meets DIN 3354 and EN 593 standards for material, design, and testing.

Technical Specifications:

1.Size Range: DN50–DN600 (2"–24")
2.Pressure Rating: PN10/16
3.Temperature Range: -15°C to +130°C (varies by seal material).
4.Connection: DIN/EN flanges (EN 1092-1).

Applications:

Ideal for HVAC systems, water treatment, food processing, and industrial pipelines with non-abrasive media.

Advantages:

1.Low maintenance with long-term sealing integrity and minimal pressure drop.
2.Cost-effective, eco-friendly design compliant with international engineering standards.
