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 chemical, energy, water technology and HVAC systems. The sturdy ductile iron body, the high-quality stainless steel disc and the replaceable elastomer seat ring ensure high tightness, durability and reliability – even with demanding media, increased temperatures and changing operating conditions. Thanks to its end fitting suitability, the KG7 can be flanged on one side and flexibly automated.
