Butterfly valves
Askalon offers trims and sizes of butterfly valves to suit most applications having to do with isolation and control of liquids, gases or slurries. We supply double flanged, high performance, hygienic, lined, resilent seated and triple offset metal seated valves.
Our complete range of butterfly valves extends from general purpose to severe service models used for isolation and throttling applications. It includes resilient seated valves for long service life and bubble tight shutoff; high performance valves capable of temperatures from cryogenic to 1500°F (815°C) and pressures to ASME Class 1500 (PN 260); double flanged valves in sizes up to NPS 120 (DN 3000) and lined valves suitable for highly corrosive liquids, gases and slurries. With a robust construction and a high cycle life, these valves will lower your total cost of ownership.
Triple offset valves outperform traditional valves with increased durability, reliability and lower ownership cost. The seat of the triple offset valve is designed to minimize wear, provide lower maintenance cost and extend service life. The ‘zero leakage’ sealing capabilities of triple offset valves provides the performance to keep your processes operating reliably at top efficiency even in extreme operating conditions. All of these benefits also come with a large weight saving when compared to many other valves, making for much easier installation and maintenance.
