Butterfly Valve
Butterfly valves are quarter-turn rotary valves used for isolation and control of fluid flow in large pipelines and industrial systems. Their compact, lightweight design makes them suitable for space-constrained installations.
As a top Butterfly Valve Manufacturer, A F Bharat Valves provides cutting-edge flow control solutions designed for high-efficiency environments, such as pre-treatment pressure filter production and large-scale industrial processing.
Our Butterfly Valve is the ideal choice for industries requiring reliable isolation or precise flow regulation. Featuring a streamlined disc design, these valves operate with a high-speed quarter-turn action—similar to a ball valve—allowing for instant shut-off and rapid response times.
By integrating high-torque Pneumatic Actuators, we eliminate the need for manual operation. This shift to automation not only reduces labor costs but significantly enhances operational safety and workplace efficiency.
Product Details
| Component | Technical Details | Component | Technical Details |
|---|---|---|---|
| Disc | For valves with NPS < 2″, a Solid Disc design is used for maximum rigidity. Sizes 2″ and above utilize Forged or Precision Cast Discs with a streamlined profile for high flow coefficients (Cv) and low pressure drop. |
Stem | One-piece, blow-out proof stem design. Precision-ground and polished surface finish ensures optimal packing performance and compliance with low fugitive emission standards. |
| Body & Connection Design | Wafer, Lug, or Flanged body designs available from Class 150 to 600. For Class 900 and above, Triple Offset designs with heavy-duty construction ensure structural integrity under extreme service conditions. |
Seat Faces | Bubble-tight shut-off with resilient soft seats (EPDM/PTFE) for general service or lapped metal-to-metal seats for high-temperature and abrasive media. Optional renewable or Stellite-faced seats available. |
| Back Sealing | Advanced secondary sealing system. Carbon steel valves feature a removable/ adjustable gland for easy maintenance. |
Gasket & Sealing | Class 150 to 600 valves use Stainless Steel + Flexible Graphite spiral wound gaskets or reinforced PTFE seals. Class 900 and above employ laminated metal seal rings or pressurized seal designs for zero-leakage performance. |
