You TubeGenerant's BLD Series Cryogenic Pressure Build Regulator

1/2" NPT
Max. Inlet 600 PSI (41.4 bar)


BLD Series Cryogenic Pressure Regulators provide high flow and shut off quickly at the desired set pressure. The regulator design is a non-balanced, spring reference, reducing type regulator and comes with PTFE seals for cryogenic use. These regulators are optimized for use in pressure build applications. The solid (non-tied) metal diaphragms provide long lasting, leak-free performance. The springs for BLD Series Regulators have been designed for optimized flow within the set pressure range. All BLD Series Regulators are supplied cleaned for Oxygen service.


  • Optimized for High Flow: Design provides high flow rates at low pressure differential.
  • Quick Shut-Off: Regulators transition from the flowing condition to shut in a tight pressure band.
  • Solid, Non-Tied, Diaphragm: Solid diaphragm eliminates the potential leak path and increases sensitivity.
  • Designed for Cryogenics: All materials were selected specifically for use in cryogenic environments.
  • Cleaned for Oxygen Service: Regulators are cleaned for use in Oxygen Service standard.
  • Extensively Field Qualified.
