What Are The Three Types Of Butterfly Valves?

The three primary types of butterfly valves are:

  1. Wafer Butterfly Valve: Wafer butterfly valves are characterized by their compact design and installation between two pipe flanges. They offer ease of maintenance and replacement, making them suitable for applications where space is limited.
  2. Lug Butterfly Valve: Lug butterfly valves feature lugs or projections on the body, which allow for direct bolting to the трубопровод. This design provides increased strength and stability, making lug butterfly valves ideal for high-pressure applications.
  3. China Triple Offset Butterfly Valve: China triple offset butterfly valves incorporate a unique design where the disc is offset in three directions – axially, radially, and angularly. This design minimizes seat wear, reduces operating torque, and enhances sealing capabilities, making triple offset butterfly valves suitable for demanding industrial applications.

Features of Wafer Butterfly Valve

  • Compact Design: Wafer butterfly valves are space-saving, making them ideal for confined areas.
  • Easy Installation: They are installed between pipe flanges, simplifying maintenance and replacement.
  • Low Pressure Applications: Suitable for low-pressure systems due to their design limitations.

Features of Lug Butterfly Valve

  • High-Pressure Applications: Lug butterfly valves are designed to withstand high pressures due to their robust construction.
  • Direct Bolting: The lugs allow for direct bolting to the трубопровод, providing increased strength and stability.
  • Durability: Lug butterfly valves are known for their durability and reliability in demanding conditions.

Features of China Triple Offset Butterfly Valve

  • Reduced Seat Wear: The triple offset design minimizes seat wear, extending the valve’s lifespan.
  • Low Operating Torque: The unique design reduces the torque required to operate the valve, making it easier to control.
  • Enhanced Sealing: The triple offset design provides superior sealing capabilities, preventing leakage.

Applications of Butterfly Valves

Butterfly valves find diverse applications across industries, including:

  • Water Treatment: Regulating water flow in treatment plants and distribution systems.
  • Chemical Processing: Controlling the flow of corrosive chemicals in chemical plants.
  • Petrochemical: Managing the flow of petroleum products in refineries and pipelines.
  • Power Generation: Regulating the flow of cooling water and other fluids in power plants.
  • HVAC Systems: Controlling airflow and temperature in heating, ventilation, and air conditioning systems.
