The Mark 93 Series is a balanced port, thermostatic sanitary steam trap designed specifically for use in validated clean steam systems. The sanitary design follows ASME BPE guidelines including a 20Ra μin internal finish, self draining design, and all relevant materials, marking and documentation guidelines.

Part #: 93C050C


  • Low subcooling operation reduces probability of SIP delays caused by temperature validation faults
  • Lay-in dimension allows drop in replacement of higher subcool, competitive traps
  • Easy thermal element (bellows assembly replacement only installs in one direction) error-proof
  • New design provides excellent flow rates with low subcooling – improves heat-up drainage
  • Self-draining when installed vertically (body outlet side down) – either vertical or horizontal connections
  • Solid barstock body with fewer cracks and crevices than competitive designs
