A C.I. (Cast Iron) Butterfly Valve is a quarter-turn flow control valve used to isolate or regulate fluid flow in pipelines. It features a disc (shaped like a butterfly wing) mounted on a rotating shaft. When the valve is open, the disc is parallel to the flow; when closed, the disc blocks the pipe to provide a tight shut-off . Poonam Industries is a leading manufacturer of these industrial valves .
The valve operates by rotating the disc 90 degrees using a lever, gear, or actuator . The disc is attached to a stem, which connects to the external operating mechanism. Turning the handle or actuator rotates the disc to either allow flow (disc parallel to flow) or stop flow (disc perpendicular to flow) .
Body: Cast Iron (Gray Iron)
Disc: S.G Iron, CF8, CF8M (Stainless Steel grades), or Polypropylene
Seat: NBR (Nitrile), EPDM, or PTFE
Stem: Stainless Steel
Compact & Lightweight: Takes up less space and is easier to install compared to gate valves .
Cost-Effective: More affordable than many other valve types .
Bi-Directional Flow: Handles flow in both directions .
Tight Shut-Off: Provides reliable sealing and leak-proof operation .
Low Maintenance: Simple design minimizes maintenance downtime .
Quick Operation: Quarter-turn (90°) operation allows for fast opening and closing .
Versatile Applications: Suitable for water, chemicals, HVAC, and more .
Poonam Industries offers C.I. Butterfly Valves in a wide size range from 2 inch (50mm) to 8 inch (200mm) and up to larger sizes . Standard pressure rating is PN10 (10 kg/cm²) . Poonam Industries can provide valves up to 600mm size .
These valves are widely used across industries :
Water Supply & Treatment: Municipal and industrial water lines.
Irrigation & Agriculture: Drip and sprinkler systems .
HVAC Systems: Heating, ventilation, and air conditioning.
Chemical Processing: Handling chemicals and corrosive fluids.
Power Generation: Cooling water and steam lines.
Oil & Gas: Pipelines and refineries.
Wafer Type: Designed to be sandwiched between two pipe flanges and held in place by flange bolts. It is more compact and cost-effective .
Lug Type: Has threaded inserts (lugs) on the body, allowing it to be bolted directly to one flange. This enables isolation of either side of the pipeline during maintenance without disturbing the entire system .
Pressure Rating: Typically PN10 (10 kg/cm²) for standard cast iron valves . Class 125 cast iron flanges can handle up to 200 psi for smaller sizes .
Temperature Rating: Up to 70°C depending on the seat material .
Cast iron (gray iron) is strong, cost-effective, and adequate for almost all commercial applications . Ductile iron offers higher tensile strength, better corrosion resistance, and greater ductility (resists cracking under stress), but comes at a higher cost . For most standard water and irrigation applications, cast iron is the economical and reliable choice.
Manual (Lever/Handwheel): Operated by hand, suitable for on/off control or simple throttling .
Actuated (Electric/Pneumatic/Hydraulic): Uses an actuator for remote control, automated processes, and precise flow regulation .
Yes. When fully closed, the disc forms a tight seal against the valve seat (rubber or elastomer), providing Class VI leakage rating and ensuring reliable shut-off .
Yes. All Poonam Industries' C.I. Butterfly Valves are proudly manufactured in India at their Ahmedabad, Gujarat facility .
Yes. Poonam Industries provides reliable after-sales support, including:
Technical installation guidance
Replacement assistance
Maintenance support
Quick response to queries
Key installation steps :
Ensure the valve disc is slightly open (about 10°) before installation to prevent seat damage.
Place the valve between flanges with proper alignment.
Insert bolts and tighten nuts gradually in a diagonal pattern with a torque wrench to the specified torque.
Ensure flange parallelism and axial misalignment are within tolerance to avoid stress and damage.
Maintenance is minimal. It generally includes :
Regular Visual Inspections: Check for wear, corrosion, or damage.
Lubrication: Lubricate the shaft and bearings as per manufacturer recommendations.
Checking the Seat: Inspect the rubber seat for wear or damage.
Inspect Disc Movement: Ensure smooth operation without excessive torque.
| Problem | Possible Cause | Solution |
|---|---|---|
| Valve won't open/close | Mechanical blockage, damaged shaft/disc, actuator problem | Isolate valve, inspect interior, remove debris, check actuator power/air supply |
| Leakage | Damaged seat, disc-seat misalignment, gasket failure | Inspect and replace seat, realign disc, replace gaskets |
| Excessive torque required | Friction in shaft/bearings, corrosion | Lubricate shaft, clean or replace corroded parts |
| Erratic actuation | Control system issues, contaminated air/fluid supply | Check control signals, install filters/separators |
