Changeover, Electrically Heated, and Vaporizing Regulators

Specialty Pressure Regulators

  • Designed to fit special applications
  • Accommodate phase changes with steam-heated and electrically heated gas vaporization models
  • Switch automatically between two gas sources with the gas cylinder changeover model, easing the burden and downtime associated with manual changeovers
  • Provide low pressure and high flow of an inert gas to the vapor space of a storage tank with a tank blanketing pressure regulator
