Designed to fit in special applications:

  • Steam-heated gas vaporization regulators (KSV series) accommodate phase changes
  • Gas cylinder changeover regulators (KCM series) switch automatically between two gas sources, easing the burden and downtime associated with manual changeovers.
  • Tank blanketing pressure regulators provide low pressure and high flow of an inert gas to the vapor space of a storage tank
