GESTRA水阀BK系列描述
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
• Repairable in-line
• Base bushing ensures positive metal-to-metal sealing between body and regulator.
• Up to ∆p 275 bar g
• Optional extra: Integrated steam trap monitoring for BK 45 (temperature or steam loss)
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
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.
