ecoflo-BT Pneumatic and Electric Butterfly Valves

Carbon Steel

ecoflo-BT series pneumatic and electric butterfly valves are designed for the control of liquids and gases from size DN 50 (2”) up to DN 2000 (80”).

Butterfly valves find their major applications in most of the process industries as well as in water distribution networks, thanks to their compact design, light weight and economy especially for larger sizes.

Butterfly valves are used mainly for on-off control applications, whereas they are also preferred for regulation service with limited control precision.

Typical control applications include regulation of temperature, pressure, flowrate and level, besides many more applications found around wherever industrial automation is involved.

Produced in Turkey under ISO 9001-2000 Quality Assurance System, ecoflo-BT series butterfly valves are used in almost all process industries like chemical and petrochemical plants, refineries, power plants, metallurgical mills, paper mills, food and pharmaceutical industries, water distribution networks, water treatment, as well as in machinery automation like textile, food and packaging.
