Spirax Sarco BT6 Balanced Pressure Steam Traps

The Spirax Sarco BT6 thermostatic balanced pressure steam trap is designed to remove condensate from hygienic and sanitary steam systems with minimal backing up. Applications include sterile steam barriers, block and bleed systems, drainage of steam distribution lines, process vessels and CIP/SIP systems. 

Manufactured in 316Lstainless steel with a crevice free body, it is self-draining and operates close to steam temperature. Where very high capacities exist or where CIP fluids are used in the process the BT6HC is recommended.

Traps are individually packaged with protective end caps and sealed in a polythene bag. 

Surface Finish
All internal wetted surfaces have a finish of 0.8 µm (32 micro-inch Ra).  Surface finish of 0.4 µm (16 micro-inch Ra) can be supplied on request by electro-polishing.
