PNEUMATIC AND ELECTRIC BUTTERFLY VALVES PN6 TO PN40 / ANSI 150 & ANSI 300
Compact designRelatively lower cost for larger sizesElastomer, polimer or metal seat optionsEN pressure classes of PN10, PN16, PN25 and PN40 or ANSI pressure classes of ANSI 150 and ANSI 300. Wafer type, lug type, flanged or welded connections Leakage Class IV, V or VIMaterials and test certificates to international standardsProcess temperature range between -30....+220˚C. Consult for different rangesProvided with pneumatic or electric actuatorsManuel override as standard for electric actuators and optional for pneumatic actuatorsChoice of analog or digital positioners of regulation serviceIP66 to IP68 protection, ex-proof modelsAmbient temperature range between -30...+60˚COptional position switches, air solenoids, lock-up valves, boosters and other auxiliary accessories
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 9001:2008 Quality Assurance System,
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.

Maximum working temperature for each pressure class and the relavant maximum working pressure values are shown in “Working Conditions” tables according to EN and ASME standards. Cast iron (GG-25) and ductile iron (GGG-40 or GGG-50) valves are suitable for mostly used industrial fluids like water, condensed water, steam and air. Cast steel (GS-C25 or WCB) bodied valves, however, are more appropriate for heavier working conditions where pressure shocks, high vibration or sudden temperature changes may occur.
Stainless steel (AISI304, 316, 316L, 316Ti) valves and thermoplastic (PP, PVC and alike) valves as well as fluoropolimer (PFA, PTFE) valves are preferred for aggressive or corrosive chemical fluids or for corrosive environment. Special exotic alloys are also available for more specific applications. One should consider the strongest possible working conditions while selecting a valve.
The torque value required to close or open a butterfly valve is dependant on valve size and pressure drop across valve, in other words, pressure difference between inlet and outlet of the valve. Typical actuator models corresponding to different valve sizes are given in “Technical Data” table, whereas these models may vary depending on valve pressure class and/or valve design.
