Bestobell Delta Element Steam Traps

Bestobell steam traps are designed for low, medium and high pressures in tracing, drip leg, and process applications through the chemical process industries. The energy-efficient design of Bestobell Steam's Delta Element steam trap lets your process use more heat energy from both steam and condensate.

Bestobell engineers designed the Delta Element specifically to reduce and correct two enduring steam trap problems — steam loss and trap failure.

Key Specifications

  • Long-term, trouble-free service
  • Single blade element, stainless internals, built-in strainer and check valve
  • Modulating discharge eliminates cyclic discharge problems
  • Excellent heat transfer and minimized corrosion by continuous venting of air and CO2
  • Long valve life — only 30% to 40% total pressure drop occurs over seating surface
