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.
