Four-Linkage Butterfly Valve

The Four-Linkage Butterfly Valve is a specially engineered valve designed for large-diameter, high-pressure, or high-temperature industrial applications. Its unique four-bar linkage mechanism ensures synchronized movement of the valve disc, providing smooth operation and improved sealing performance. This design minimizes deformation under high stress and ensures long-term reliability. The valve body is typically constructed from durable materials such as carbon steel or stainless steel, offering excellent resistance to corrosion and mechanical wear. It is widely used in industries such as power generation, metallurgy, petrochemicals, and municipal water systems. The Four-Linkage Butterfly Valve is ideal for systems requiring precise flow regulation, large volume control, and consistent sealing, even under challenging working conditions.

Description

Product Description

The Four-Linkage Butterfly Valve is a high-performance industrial valve designed with a four-bar linkage mechanism to enhance structural stability and sealing performance. This advanced design enables the valve disc to open and close uniformly, minimizing torque and reducing wear on the sealing surface. The valve is particularly suitable for large-diameter pipelines and systems requiring reliable sealing under high pressure or temperature conditions. The body is typically made from carbon steel, stainless steel, or other corrosion-resistant alloys, ensuring long service life and durability in harsh environments.

Functional Parameters

  • Nominal Diameter: DN200–DN3000 (customizable)
  • Working Pressure: Up to 2.5 MPa
  • Operating Temperature: -20°C to +450°C
  • Sealing Type: Metal or soft seal, depending on the medium
  • Drive Options: Manual, pneumatic, electric, or hydraulic actuators

Application Areas

  • Power Plants: For controlling air and flue gas flow in desulfurization and dedusting systems
  • Steel and Metallurgy: Used in hot blast systems and gas pipelines
  • Petrochemical Industry: For large-scale fluid control under high pressure and temperature
