Fire-safe version for high pressure and high temperature
The KSB DANAIS 150 is a double-eccentric high-performance butterfly valve for demanding industrial applications in power, chemical, oil and gas and process plants. Thanks to its eccentric construction, the robust steel or stainless steel design and certified fire-safe technology it offers maximum operational reliability under high pressures, temperatures and media loads. The DANAIS 150 is available in wafer and lug design and meets all relevant international standards for tightness, safety and automation.
Double-eccentric construction → less wear, longer-lasting seat
Fire-safe version to API 607 / ISO 10497
Plastomer, fire-safe or metal seat depending on the application
Operating temperature from −29 °C to +260 °C
Pressure ratings up to PN 40 (wafer/lug)
Robust body materials: cast steel ASTM A216 WCC or stainless steel CF8M
Stainless steel disc CF8M for high corrosion and temperature resistance
High tightness through a two-stage sealing system (Viton O-ring + graphite)
ISO 5211 actuator flange → ideal for electric & pneumatic automation
Extremely reliable industrial valve for safety-critical systems
The DANAÏS 150 is the high-performance valve in the KSB range: DN 50 to DN 1200 at 25 bar, with a metal seat also for hot media and media laden with solids. For water at 10 bar the ISORIA is sufficient.
