  • Vahn-Tech Series 100, 200, 300 & 400 are rubber lined concentric butterfly valve designed as economic solution for lower pressure isolation applications where weight and face-to-face requirements are valued greater than the rated flow capacity.

  • Vahn-Tech Series DOBF is a cost-effective butterfly valve solution for isolation valve applications. Providing lighter weight, smaller face-to-face, and simple quarter-turn rotary movement, a double-offset butterfly valve design is a great solution for zero-leakage isolation relative to ball valves for large sizes. With the eccentric disc designed to reduce the rubbing of the seat it drastically reduces torque requirements for actuation while extending seat life expectancy.

  • Vahn-Tech Series LBFV is a fluoropolymer lined concentric butterfly valve designed for chemically corrosive process medias. The design features enhanced seat energizer along with mechanically loaded packing arrangement to mitigate any media propagation past the stem.

  • The Vahn-Tech Series TOV and TOBF triple offset butterfly valves are designed to meet the critical zero-leakage isolation requirements for industry applications. Split into two primary design categories, floating and fixed seats, there's versatility in the selection to match your process requirements and project economics.
    Triple Offset
  • The NAF Torex, High-Performance butterfly valve is available with either metal-to-metal or soft seats. Due to its unique design and triple offset, it closes extremely tight. It can be used both as a control valve and as a shut-off valve.This valve can be supplied in either wafer or lugged versions. The valves are also available in other materials e.g. Carbon steel, and Titanium, other stainless steel materials and in Fire-safe design.
