Product Introduction

The ductile iron electric flanged butterfly valve combines a high-strength ductile iron body with electric actuator and flanged connection, designed for industrial fluid control systems. The ISO 5211 compliant flanges ensure leak-proof pipeline integration, ideal for flow regulation in water treatment, HVAC, and energy applications. EPDM soft seats provide bidirectional zero leakage at PN16 pressure (-20℃~120℃), compatible with water, air, and mild corrosive media. The actuator supports on/off and modulating control for seamless automation integration.

Product Features

- Flanged benefits: Precision-machined flange faces for global pipeline compatibility.

- Corrosion resistance: Epoxy-coated ductile iron body withstands 1500+ hour salt spray.

- Smart actuation: ＜5s response time with 4-20mA signal input (±2% accuracy).

- Resilient sealing: EPDM seats maintain sealing integrity over 50,000 cycles.

- Low flow resistance: Full-bore design with flow coefficient of 0.2 reduces energy loss.

Product Advantages

1. Industrial durability: 25bar pressure rating with 10+ years service life.

2. Automation-ready: Remote control capability enhances operational efficiency.

3. Easy maintenance: Flanged connection eliminates welding, cutting downtime by 40%.

4. Cost-effective: 35% lower cost than stainless steel alternatives with equal performance.
