Lug-type butterfly valve in stainless steel: DVGW gas approval
The AK211G stainless steel lug type butterfly valve designed for gas applications stands out for its impressive performance, durability, and top-notch safety features. Its concentric and flanged design makes it an ideal choice for installation between flanges to PN10/16 (DIN) and/or Class150 (ASME). Typically, these gas butterfly valves come with a user-friendly hand lever made from either aluminum or ductile iron. In addition, they can also be automated with pneumatic or electric actuators, thanks to the adaptable ISO 5211 top flange, catering to the specific needs of your application. With DVGW gas approval in accordance with DIN EN 13774, this butterfly valve meets essential industry standards, ensuring maximum safety and reliability for both natural gas supply and industrial gas systems.
