Product Description

Product Description

 

 

A flange wafer butterfly valve is a compact and lightweight flow control device commonly used in various industries for isolating or regulating flow. Its wafer-style design fits between two pipeline flanges, making it cost-effective and easy to install.

Key Features:

1. Wafer Design:

   • The valve body is sandwiched between two flanges, held in place by bolts.
   • No flange holes in the valve body; alignment is achieved through the pipeline flanges.

2. Flanged Connection:

   • Compatible with standard flanges (ANSI, DIN, JIS, etc.).
   • Ensures secure and leak-proof connections.

3. Disc and Shaft Assembly:

   • A rotating disc controls the flow.
   • The shaft passes through the center, connecting to an actuator or handle.

4. Sealing Options:

   • Resilient seats (like EPDM, PTFE, or NBR) for tight shut-off.
   • High-performance or metal-seated options for high-pressure and temperature applications.

5. Materials:

   • Body: Cast iron, ductile iron, stainless steel, or other alloys.
   • Disc: Stainless steel, aluminum-bronze, or coated materials for corrosion resistance.
   • Seat: Soft or hard materials depending on fluid type and temperature.

6. Operation:

   • Manual (lever or gear-operated).
   • Automated with pneumatic, electric, or hydraulic actuators.

7. Pressure and Size Range:

   • Typically rated up to ANSI Class 150 or PN16.
   • Sizes range from small diameters (e.g., DN50) to large sizes (e.g., DN1200).

Advantages:

• Compact Design: Saves space and reduces weight compared to flanged or lugged butterfly valves.
• Cost-Effective: Simple construction and easy installation lower overall costs.
• Quick Operation: 90-degree rotation allows for rapid opening and closing.
• Low Maintenance: Fewer parts result in reduced maintenance requirements.
• Versatility: Suitable for handling liquids, gases, and some slurries.

Common Applications:

• Water Treatment: Flow control in potable water and wastewater systems.
• HVAC Systems: Regulating heating, cooling, and ventilation pipelines.
• Food and Beverage Processing: Hygienic and corrosion-resistant designs for process control.
• Chemical Industry: Handling non-corrosive and mildly corrosive chemicals.
• Fire Protection Systems: Quick shut-off in sprinkler systems.
