Bellow sealed valve Type VG065

Bellow sealed valve with DIN/ASME flange

The VG065 bellow valve from FERGO Armaturen GmbH is not only a premium and versatile solution but also a product built on decades of industry expertise. In particular, its innovative design incorporates welded, multi-layer bellows that deliver exceptionally reliable sealing. Furthermore, the valve features a 360° rotatable conical plug paired with an integrated seat, enables precise control while simultaneously extending the valve’s lifespan. With an ergonomic handwheel and precision manufacturing, the bellows valves are ideal for applications in the medium to high pressure range, e.g. in systems for steam, superheated steam, gases, thermal oil and superheated water.

Moreover, the VG065 bellow valve is equipped with robust body and bonnet made of high-quality steel (1.0619/ASTM A216) and uses high-quality materials for both the plug and the seal. As a result, it is designed to withstand even the most extreme conditions. In addition, the valve is available in a range of configurations—from DIN PN40 according to EN 1092-1 Form B to ASME B16.5 flange connections in Class 150, 300, and 600—which ensures a perfect fit for every application. With nominal sizes ranging from DN 15 to DN 300, these valves provide optimal leak-tight performance and additionally can also be individually customised to meet specific requirements.

Furthermore, the VG065 bellow sealed valve is certified to international standards such as TA Luft, AD2000, ATEX, and Firesafe, thereby standing as a testament to superior quality, reliability, and environmental compatibility. These qualifications have helped us earn the trust of customers around the world with our commitment to excellence based on a proven track record.
