Product Description

Product Description

The flanged butterfly valve utilizes a disc-shaped closing element (butterfly plate) that rotates 90° for on/off control. With flanged connections, it features compact structure, quick operation, and precise flow regulation, widely used in low/medium-pressure pipelines in oil, chemical, water treatment, and power industries.

 Key Advantages of Flanged Butterfly Valves

1. Compact Design, Space-Saving

• Advantage: Compared to gate valves and globe valves, flanged butterfly valves are 30-50% lighter and more compact, making them ideal for space-constrained piping systems.

• Applications: Ships, underground pipelines, and densely packed industrial plants.

• Technical Basis: The disc rotates 90° for full open/close, eliminating the need for a rising stem.

2. Quick Operation & Precise Flow Control

• Advantage: Instant 90° rotation (1-2 seconds) for full operation, with partial opening capability for accurate flow regulation (softer seals offer better modulation).

• Vs. Competitors: Gate valves require multiple turns; ball valves are fast but less precise for throttling.

• Use Case: Systems requiring frequent operation or flow adjustment (e.g., cooling water loops).

3. Superior Sealing Performance

• Soft Seals (Rubber/PTFE): Bubble-tight leakage (Zero Fugitive Emissions), ideal for water, gases, and mildly corrosive media.

• Hard Seals (Metal/Alloy): Withstand high temperatures (≤600°C) and pressure (PN40/ANSI 600#), suitable for steam and oil.

• Innovation: Triple-offset design ensures zero-friction sealing, extending service life 3-5x.

4. Low Flow Resistance, Energy-Efficient

• Advantage: Fully open disc aligns with flow, reducing pressure drop to 1/10th of gate valves, cutting pump energy costs.

• Data: Pressure loss <0.1 bar (for water, DN200).

• Ideal For: High-flow systems (e.g., municipal water, power plant cooling).

5. Easy Maintenance & Cost-Effective

• Maintenance: Seat/seal replacement possible without valve removal (certain designs).

• Cost Savings: 40% lower upfront cost vs. gate valves; 50% cheaper installation (flanged connection simplicity).

• Case Study: Petrochemical plants report 30% lower annual maintenance costs.

6. Versatile Adaptability

• Actuation Options: Manual (lever/gear), electric, pneumatic, or hydraulic.

• Material Flexibility:

  • Body: Cast iron (cost-effective), SS316L (corrosion-resistant), duplex steel (high strength).

  • Seals: EPDM (acid/alkali resistance), NBR (oil-resistant), PTFE (chemical-proof).

• Industry Compliance: From FDA-grade (food/pharma) to ASME III (nuclear).
