֕ Robust regulator for roughest operating conditions (unaffected by waterhammer and frost) Suitable for superheated steam applicationsՕ Automatic air-venting (steam trap can be used for thermal air-venting in steam systems) Installation in any position (horizontal and vertical lines)Օ Stage nozzle acts as non-return valve Stainless steel internals Օ Repairable in-line Base bushing ensures positive metal-to-metal sealing between body and regulator.Օ Up to ∆p 250 barg Optional extra: Integrated steam trap monitoring for BK 45 (temperature or steam loss) L BK 45, BK 46 DN 15, 20, 25 For open-loop controlled heating processes. Draining ofՖ saturated steam lines superheated steam lines ֖ steam tracersCan also be used for thermal air-venting 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.
