The L&T Wafer Butterfly Valve is a high-quality valve used for controlling the flow of fluids in a wide range of industrial applications, including water treatment, HVAC systems, chemical processing, and more. The wafer-style design of this butterfly valve allows it to be installed between two pipe flanges, making it space-efficient and cost-effective.

L&T Wafer Butterfly Valve Specification1. Valve Type:

• Butterfly Valve: A quarter-turn valve used to regulate fluid flow by rotating a disc within the valve body.
• Wafer Type: The valve body is designed to be inserted between two pipe flanges, clamped by bolts, making it a compact and space-saving solution.
• Manual or Actuated Operation: Available in both manual and automated configurations (electric, pneumatic actuators).

2. Size Range:

• Typically available in sizes ranging from 2" (DN 50) to 48" (DN 1200).
• Custom sizes may be available for special applications.

3. Pressure Rating:

• Standard pressure ratings:
  • ANSI 150 (PN 20)
  • ANSI 300 (PN 50)
• The pressure rating depends on the valve size, material, and design. Higher pressure ratings may be available for special applications.

4. Temperature Rating:

• Common operational temperature range: -10°C to +110°C (14°F to 230°F).
• High-temperature versions can be designed for applications with higher temperature resistance.
• Special materials such as PTFE or Viton seals are available for higher temperature requirements.

5. Body Material:

• Cast Iron (GG25 or GGG40) for general-purpose use.
• Ductile Iron for stronger, more durable applications.
• Carbon Steel or Stainless Steel (SS 304, SS 316) for corrosive or aggressive fluid applications.
• Aluminum or other alloys may be offered depending on the application.

6. Disc Material:

• Typically made from Cast Iron, Stainless Steel (SS 304, SS 316), or Aluminum.
• Coatings such as PTFE, PVC, or other corrosion-resistant coatings may be applied for more aggressive media.

7. Stem Material:

• Made from Stainless Steel (SS 416, SS 304, SS 316) or Hardened Stainless Steel to ensure durability and resistance to corrosion.

8. Seal Material:

• EPDM for general fluid handling (water, air, etc.).
• Viton or PTFE for chemical-resistant applications or high-temperature environments.
• NBR for oil-based media.
• Neoprene or PTFE seals are also available depending on fluid compatibility.
