Concentric Butterfly Valve
Precision Flow Control
Unveiling Concentric Butterfly Valves by Lipin
The structure of the concentric butterfly valve is characterized by the stem axis, the center of the butterfly plate, and the center of the valve body in the same position. The stem moves along the center line of the disc without any deviation. Our concentric butterfly valves have a full-diameter construction to reduce flow resistance and ensure smooth flow through the valve. The seat of the concentric butterfly valve basically uses rubber or polytetrafluoroethylene and other elastic materials to overcome extrusion, scratching, and ensure sealing performance.

Why do you choose Lipin Concentric Butterfly Valves

Regarding excellent fluid control, Lipin is a reliable brand in the industry, especially for the concentric butterfly valve. The following is a diving of why the concentric butterfly valve of Lipin is a prudent choice.
  • Unique simplicity
    The goal of Lipin concentric butterfly valve is to achieve consistent matching of valve plate, shaft and valve body axis. This symmetry is important for ensuring a consistent and reliable seal, maintaining even pressure and minimizing wear.
  • Quality materials
    In addition to traditional carbon steel, Lipin also offers stainless steel and duplex stainless steel to increase elasticity against corrosive corrosion.
  • Strive for excellence
    Lipin manufactures valves to strict standards, in compliance with ASME 150 and 300 benchmarks.
  • Efficient Flow Control
    Our concentric butterfly valve is widely used for liquid flow control due to its cost-effectiveness. It’s easy to operate, maintain, and offers long-lasting performance.
  • Simple Central Design
    The valve's stem is centrally located, with a disc positioned in the middle of the valve. This simple structure ensures reliable flow control and easy handling.
  • Lightweight and Durable
    The valve is lightweight, making it practical for various uses. Its components are durable and comparable to other high-quality flow control systems.

Key Components of Concentric Butterfly Valves

The Concentric Butterfly Valves mainly consists of the following nine parts. This component ensures that the Butterfly valve remains efficient and stable during operation and maintains a zero leakage record.
  • Body
    Defines the fluid's route.
  • Disc
    Central regulator of fluid flow.
  • Stem
    Rotates the disc in alignment with the body.
  • Seat
    Ensures tight sealing against leaks.
  • Actuator
    Drives the valve's movement.
  • Seals
    Counter internal fluid leaks.
  • Retaining Ring
    Anchors the disc to the stem.
  • Central Bushing
    Provides stability and alignment.
  • Bearings
    Aid in smooth valve rotation.
  • Advantages of

    Concentric Butterfly Valves

    • 01
      They take up less space than other valves
      They take up less space than other valves.
    • 02
      Due to its compact and lightweight form
      Due to its compact and lightweight form, installation, maintenance and labor costs are reduced.
    • 03
      Because the seat is constructed
      Because the seat is constructed as a sleeve or spool inside the valve body, the medium flowing through the valve does not touch the valve body.
    • 04
      Concentric butterfly valves are easier to install
      Concentric butterfly valves are easier to install.
    • 05
      A variety of seat and disc
      A variety of seat and disc materials are available for different industrial applications.
    • 06
      These valves require
      These valves require less support to close than industrial ball valves.

    Why Opt for Concentric Butterfly Valves?

    The concentric butterfly valve has a simple structure and is composed of fewer components, making it easier to operate and maintain. The valve adopts full diameter structure to regulate the flow rate and ensure the smooth passage of fluid.
