Standard applications in water, energy and chemical plants
The GEFA butterfly valve KG7 in lug design is a robust, centric and soft-seated industrial valve for demanding applications in the chemical industry, power generation, water technology and HVAC systems. The sturdy ductile iron body, the high-grade stainless steel disc and the replaceable elastomer seat ring provide high tightness, durability and reliability – even in demanding media, at elevated temperatures and under changing operating conditions. Thanks to its end-of-line capability the KG7 can be flanged on one side and automated flexibly.
The threaded lugs of the KG7 take up the flange bolts – this allows the downstream pipe to be dismantled without loosening the valve. For pure wafer installation the KG9 is sufficient.
