BT6-B sanitary balanced pressure thermostatic steam trap

The BT6-B is a 316L sanitary balanced pressure thermostatic steam trap for clean and pure steam. Its crevice-free, self-draining body and angled seat minimise condensate retention, supporting hygienic performance in SIP/CIP, sterile steam barriers, mains drainage and other regulated clean steam applications.

The high-performance thermostatic element with minimal subcooling which enables typical cooling leg requirement to be reduced to 50mm.

• Protects product quality and patient safety
  Minimises condensate retention and pooling to help maintain hygienic conditions during SIP/CIP and production, supporting sterility and clean steam quality. 
• Supports reliable SIP and validation
  Self draining geometry and reduced cooling leg improve drainage predictability and cycle repeatability, helping to reduce validation failures and lost batch time.
• Reduces steam loss and energy waste
  Near saturation closing of the thermostatic capsule and tight seal limits unnecessary live steam loss compared to traps that operate significantly below steam temperature. 
• Simplifies specification in regulated utilities
  Hygienic design, material traceability and documentation packages (including EN 10204 3.1, FDA, USP and Food+ EC1935 statements) make it easier to demonstrate compliance during audits.
• Speeds up installation and commissioning
  Compact geometry with a reduced cooling leg helps designers fit drain points where they are most effective and reduces commissioning time around steam and condensate lines. 
• Flexible for global hygienic standards
  Clamp and tube ended connection options allow the same sanitary trap platform to be applied across ASME BPE PED/UK PESR, FDA CFR Title 21 gasket compliance, USP Class VI, ADI/TSE/BSE free) and cleanroom packaging (ISO Class 7), ensuring full alignment with recognised hygienic piping standards.
• Designed for maintainability
  Clear installation guidance, clamp torque cautions and easily specified spares (capsule assembly and gaskets) help maintenance teams service the trap without damaging hygienic surfaces. 

Note: Local regulations and clamp/gasket selection may restrict the operating envelope; always consult Spirax Sarco technical information and Installation and Maintenance Instructions before use. 

In hygienic and clean steam systems, “any trap” is no longer good enough. BT6-B brings together Spirax Sarco’s steam expertise and hygienic design know how in a single, validated sanitary steam trap platform. It is purpose built for condensate removal in regulated environments, combining a self-draining 316L body, the benefit of a reduced cooling leg, and near to steam thermostatic operation to support reliable SIP/CIP performance and product quality. 

Backed by cleanroom packaging, extensive certification and global application support, BT6-B helps utilities engineers, process owners and QA teams standardise on a single, audit ready solution for clean and pure steam condensate removal—reducing complexity while protecting uptime and compliance.
