For liquids, gases and steam in heating, ventilation, air conditioning and industrial processes
The GEFA butterfly valve KG9 in wafer design is a compact, centric and soft-seated industrial valve for applications in chemical, energy and water technology. Thanks to a robust grey cast iron body, a durable elastomer seat ring and a high-grade stainless steel disc, the KG9 offers a reliable, service-friendly solution for liquids, gases and steam. It stands out through its compact design, high tightness and flexible automation capability – ideal for industrial processes, HVAC systems and modern plants.
The KG9 is the wafer version of the KG7 – it is clamped between flanges. The MULTITOP mounting plate allows actuators with a larger connection flange to be mounted directly without a special adapter.
