Thermostatic Steam Traps BK with Duo Stainless Steel (Bimetallic) Regulator PN 0 – PN 0 BK 45, BK 46 DN 15, 20, 25 L L BK 15, DN 40, 50 Features of the BK series • Robust regulator for roughest operating conditions (unaffected by waterhammer and frost) • Suitable for superheated steam applications • Automatic air-venting (steam trap can be used for thermal air-venting in steam systems) • Installation in any position (horizontal and vertical lines) • Stage nozzle acts as non-return valve • Stainless steel internals Application For open-loop controlled heating processes. Draining of – saturated steam lines – superheated steam lines – steam tracers Can also be used for thermal air-venting Air-venting Pressure/Temperature Ratings * ) Type PN Class ∆ PMX [bar] • Repairable in-line • Base bushing ensures positive metal-to-metal sealing between body and regulator. • Up to ∆p 250 bar g • Optional extra: Integrated steam trap monitoring for BK 45 (temperature or steam loss) Steam trap for thermostatic air-venting with bimetallic regulator The thermostatic steam traps with corrosion-resistant Duo S.S. (bimetallic) regulator of the BK series can also be used for air-venting. Application Thermostatic steam trap for automatic air-venting and discharge of non-condensable gases and steam/air mixtures from steam lines and heat exchangers. Special adjustment might be required.
