Wafer Butterfly Valve

Product Overview

The Wafer Butterfly Valve is a compact quarter-turn valve designed for regulating and isolating flow in pipelines. It is installed between two pipe flanges using long bolts, making it lightweight, space-saving, and easy to install. It is widely used in water, gas, HVAC, and industrial process systems.

Key Features

• Wafer-style compact design for easy installation
• Lightweight structure with low space requirement
• Quarter-turn operation for quick opening and closing
• Low pressure drop and smooth flow characteristics
• Available with manual, electric, or pneumatic actuators
• Excellent sealing performance (soft seat or metal seat options)
• Corrosion-resistant body materials available
• Suitable for bi-directional flow

Applications

• Water supply and drainage systems
• HVAC and air handling systems
• Chemical and industrial processing
• Power plants and energy systems
• Oil and gas pipelines (non-critical services)
• Food and beverage industries
• Fire protection systems
