Triple Eccentic Butterfly Valves

Unparalleled in terms of quality and adaptability, Flowrates model BVT01 is manufactured on-demand in order to reach your highest expectations.

  • Metal/Metal tightness by direct contact without jamming the butterfly ring on the seal, also known as “eccentric” butterfly valve
  • Tight closure security : the closing position is ensured directly by the metal Seat’s contact on the disc metal ring
  • No friction from the first degree of opening for low wear out and improved longevity

Technical Advantages of Triple Eccentric Butterfly Valves

  • Better trade-off of mass, face-to-face and nominal diameter than other types of metal/metal valves (ball valves, gate valves, globe valves)
  • Face-to-face dimensions compliant with EN558 Series 20.
  • Optimized disc and two-piece shaft design to achieve a high flow coefficient (low pressure drop).
  • Unique design with a retaining ring, allowing all parts to be replaced directly on-site without the need to return the valve to the factory.
  • Internal protection ring for bushing , preventing any particles from getting in
  • Intrinsic Fire safe Pressure (BS 6755 part 2, API607)
  • Mounting plate ISO 5211
  • A metallic gasket for every application. Laminated graphite / Solid stainless steel gasket / Monobloc disc
  • Available connections: Wafer / Lug / Flanges series 13 and 14 / butt-welded
