China DN50 Ductile Iron Wafer Butterfly Valve Manufacturer | High Quality & Factory Price

Premium DN50 Ductile Iron Wafer Butterfly Valve for Industrial Piping Systems

Welcome to FTJ Valves, your trusted partner and leading China DN50 ductile iron wafer butterfly valve manufacturer. We specialize in engineering and producing high-performance flow control solutions designed for demanding municipal, commercial, and industrial applications.

Our DN50 ductile iron wafer butterfly valve is specifically crafted to offer superior durability, compact design, and tight shut-off capabilities. Built with high-grade ductile iron (QT450-10/GGG40), this 2-inch valve provides significantly higher tensile strength and impact resistance compared to standard cast iron valves, ensuring long-term operational stability under challenging fluid control conditions.

Key Features & Engineering Excellence

• High-Strength Ductile Iron Body: Offers exceptional pressure containment, reducing the risk of body cracking under hydraulic shock or thermal expansion.

• Space-Saving Wafer Design: Designed to fit seamlessly between international pipe flanges (ANSI, DIN, JIS, BS), allowing for quick, low-cost installation and easy maintenance.

• Bi-Directional Bubble-Tight Seal: Features a resilient EPDM or NBR seat that guarantees zero leakage in both flow directions.

• Corrosion Protection: Coated with electrostatically applied epoxy powder (min. 250 µm thickness) inside and out, providing excellent resistance against rust, chemicals, and harsh weather.

Ideal Applications

The china dn50 ductile iron wafer butterfly valve is widely utilized across various global industries, including:

• Water treatment and supply networks

• HVAC and cooling water systems

• Fire protection and irrigation

• Industrial liquid processing and chemical handling
