A Cast Iron (CI) Butterfly Valve is a quarter-turn rotary valve designed for regulating, isolating, and controlling fluid flow in pipelines. The valve operates by rotating a disc inside the pipeline, allowing quick shut-off and efficient throttling with minimal pressure loss.
Construction Details
Body Material: Cast Iron (CI)
Disc Material: Cast Iron / Ductile Iron / Stainless Steel (as required)
Seat Material: EPDM / NBR / PTFE (soft seated for tight shut-off)
Shaft: Stainless Steel for corrosion resistance
End Connection: Wafer / Lug / Flanged type
Operating Mechanism
The valve works on a 90-degree rotation principle, operated manually using a lever or gearbox, or automatically using pneumatic/electric actuators.
Pressure Rating
PN10 / PN16 or Class 150 (depending on design requirement)
Applications
Water supply systems
HVAC systems
Fire protection systems
Industrial piping
Irrigation networks
Features
Compact and lightweight design
