| Product Name | Handle-Operated Flanged Butterfly Valve |
| Product Type | A quarter-turn rotary valve controlled by a manual hand lever or gear operator, featuring flanged ends for bolted connection to the piping system. |
| Key Components | Body: Typically cast iron, ductile iron, or stainless steel, with integrated flanges. Disc: The flow control element, usually made of stainless steel or coated for corrosion resistance. Seat: A resilient seal (e.g., EPDM, NBR). Stem: The shaft connecting the disc to the handle. Handle (Lever): A manual operator for quick 90° action. |
| Operating Principle | The handle moves the disc from a fully open (0°) to a fully closed (90°) position. Flanges provide a strong, bolted connection to pipeline mating flanges with a gasket. |
| Key Features | - Manual Operation: Simple and direct control via a lever handle. - Flanged Ends: Provides a robust, leak-proof connection suitable for higher-pressure applications. - Visual Position Indicator: The handle position clearly shows the valve status (open/closed). - Compact Design: Lighter and shorter than same-size gate valves. - Cost-Effective: Low initial and maintenance cost. |
| Primary Advantages | Simple operation, reliable flanged connection, easy maintenance, excellent shut-off, and suitability for a wide range of media. |
| Typical Applications | - Water Supply and Distribution Networks - Fire Protection Systems - HVAC Systems - Industrial Water Cooling Lines - Wastewater Treatment Plants |
