General advantages of butterfly valves:

  • Low-pressure drop, consequently energy saving.
  • Lower weight and dimensions than other types of valves.
  • Maximum purchase benefits and low maintenance.
  • Easy and safe operation.
  • Only disc and liner are in contact with the fluid.

Advantages of the exclusive VAMEIN design, complementary to the general ones of butterfly valves

  • Quality Management System according to ISO 9001:2015.
  • No gaskets necessary for installation between flanges.
  • Maintenance free.
  • Liners easy to replace.
  • Due to the Disc - Shaft connection design with no pins, screws or keys and narrow machining tolerances of its components all parts of the valve are interchangeable.
  • Extreme low operating torque.
  • Possibility to use it as control (regulating) valve.
  • Self-cleaning.
  • Cavity free.
  • Thanks to the centring holes enabling a correct alignment and a fast installation easy to place in the pipeline.
  • Enables the use of insulation in heat-resistant installations.
  • Quality identification for material: each body, disc and liner is marked with its code number to have a perfect quality traceability of the materials used for their production. Thus with the Heath Number our Quality Assurance Department obtain a perfect traceability of the quality of materials, enabling them to know at any time the chemical composition and mechanical properties.
  • Descriptive label indicating: name of manufacturer, valve figure description, maximum working pressure, maximum working temperature, flange standard and country of origin.
  • Thermo-contractive polyethylene individual packing up to DN 300 (12”).
  • Possibility of marking to Pressure Equipment Directive 2014/68/EU , European Directive ATEX 2014/34/EU concerning equipments and protective systems intended for use in potentially explosive atmospheres, and certificates to work with drinking water for human consumption.
