Application scenarios
Clean Steam Condensate Drainage for Sterilizers
Used in clean steam systems serving sterilizers to discharge condensate generated during operation at the condensate drain point. The product is designed for clean steam systems and discharges condensate at temperatures close to steam saturation.
Clean Steam Condensate Drainage for Process Vessels
Used to drain condensate from clean steam piping associated with process vessels. The product features an AISI 316L stainless steel body, a high-quality internal surface finish, and a self-draining design.
Clean Steam Piping Drainage in CIP Systems
Used in clean steam piping for CIP systems to discharge steam condensate at drain points. The product documentation specifies suitability for CIP/SIP systems and connection types compatible with clean steam systems.
Condensate Drainage During In-Place Steam Sterilization in SIP Systems
Used to discharge condensate during steam sterilization in SIP systems. The product documentation specifies suitability for CIP/SIP systems and permits installation in vertical piping with downward flow.
Selection points

Installation & maintenance notes
Install Vertically with Downward Flow
The BTM7 must be installed in vertical piping with the process medium flowing downward.
Operate Within the Allowable Pressure and Temperature Limits
Site operating conditions must not exceed the maximum allowable pressure of 7 bar g at 170°C, the maximum operating pressure of 7 bar g for saturated steam, or the maximum operating temperature of 170°C.
FAQ
Which clean steam system applications are suitable for the BTM7?
The BTM7 removes condensate from clean steam systems and is suitable for applications including sterilizers, process vessels, and CIP/SIP systems. It discharges condensate at temperatures close to steam saturation and features a self-draining design.
What installation orientation is required for the BTM7?
The BTM7 must be installed in vertical piping with the process medium flowing downward to ensure that condensate can drain freely. Suitable isolation valves should be installed upstream and downstream of the steam trap to facilitate safe maintenance and replacement.
Which connection types and sizes are available for the BTM7?
Available options include threaded, imperial butt-weld, sanitary clamp, and DIN 11850 or ISO 1127 series butt-weld connections. Corresponding threaded and sanitary clamp sizes are available in 1/4", 1/2", 3/4", and 1". The exact configuration must be confirmed according to the specific model and application conditions.
What are the maximum operating pressure and temperature of the BTM7?
The BTM7 has a maximum operating pressure of 7 bar g under saturated steam conditions, a maximum operating temperature of 170°C, and a minimum operating temperature of 0°C. The maximum allowable body pressure is 7 bar g at 170°C, and the maximum design cold hydraulic test pressure is 10.7 bar g.
Which replacement parts are available for the BTM7, and what information is required when ordering?
Available replacement parts include the thermostatic element, O-ring seals (3 sets), and the outlet body with valve seat. When ordering replacement parts, specify the steam trap model, size, and connection type. The connection configuration must also be specified when ordering the outlet body.
