Butterfly valve is a lightweight, compact flow control valve, widely adopted in large-diameter pipeline systems. It is popular for its space-saving design and fast installation.
Basic Butterfly Valve Structure
Consists of valve body, disc, rubber/PTFE seat, stem and operating device (lever, gear or electric actuator). The disc rotates 90° to control flow.
Core Benefits of Butterfly Valves
- Light weight, much smaller installation space than gate valve
- Fast 90-degree operation
- Competitive price for large size
- Multiple actuator options for automatic control
Limitations You Should Know
Not suitable for ultra-high pressure and strong abrasive medium; pressure loss is higher than full-port ball valves.
Main Application Industries
- Water treatment & wastewater
- HVAC, power plant circulating water
- Chemical low-corrosion fluid
- Shipbuilding pipeline system
Buying Tip
Select seat material according to medium: EPDM for water, PTFE for chemical medium.
