Product Description
Classic and Efficient DN800 Wafer Butterfly Valve
The preferred choice for stable flow control in large-diameter piping systems
Product Overview
Our DN800 Wafer Type Butterfly Valve delivers superior performance for reliable, efficient, and economical flow regulation. Engineered to ANSI/API standards, this valve provides excellent shut-off capability, durability, and ease of operation across various industrial applications including water treatment, HVAC, power generation, and process industries.
Key Features & Benefits
- Robust Construction: High-grade materials including ductile iron, carbon steel, or stainless steel provide exceptional strength and corrosion resistance
- Superior Sealing: Resilient seat options (EPDM, NBR, or PTFE) ensure bubble-tight sealing under varying pressure and temperature conditions
- Compact Wafer Design: Simplified installation between ANSI flanges reduces space requirements, weight, and overall system costs
- Low Torque Operation: Streamlined disc design and quality bearing system minimize operating torque with multiple actuation options
- Bidirectional Flow: Reliable sealing and control for flow in either direction enhances application versatility
- Long Service Life: Minimal maintenance design with protected stem and easily replaceable seat components
