Understanding the Concentric Butterfly Valve

A concentric butterfly valve, often referred to as a "standard" or "rubber-lined" butterfly valve, is the backbone of general-purpose flow control. In this design, the stem is centered in the middle of the disc, and the disc is centered in the bore.

Why Choose Flowtorq Concentric Valves?

  • Simple Efficiency: The centered design allows for bi-directional flow and a streamlined body that is easy to install.

  • Cost-Effective: Due to their straightforward mechanical design, these valves offer an economical solution for low-pressure applications without sacrificing quality.

  • Versatility: Flowtorq manufactures these valves in various materials, including ductile iron and stainless steel, to suit your specific media requirements.

The Advantages of Resilient Seated Butterfly Valves

When a bubble-tight shut-off is critical, the resilient seated butterfly valve is the industry's go-to choice. These valves feature an elastic (resilient) seat—typically made of EPDM, Viton, or Nitrile—wrapped around the internal diameter of the valve body.

Key Features of Flowtorq Resilient Seated Valves:

  • Zero Leakage: The interference fit between the disc edge and the resilient seat ensures a 100% airtight seal.

  • Corrosion Resistance: Our seats are designed to protect the valve body from the processed media, significantly extending the service life of the hardware.

  • Low Maintenance: The replaceable seat design means you can refurbish the valve in the field rather than replacing the entire unit, reducing downtime and operational costs.

  • Size Range – 2″ to 40″

  • Pressure Rating – 150#, 300#, PN6, PN10, PN16, PN25

  • Certifications – ISO, CE, Atex, etc.

  • Inspected & Witnessed By third party agencies

  • API Valves, ATex Valves, CE Valves, Process Valves, Gas Valves, Water Valves, Cryogenic Service, Fire Safe
