  • Regulator specification: see following table
  • Inlet & Outlet: ¼” FNPT

Product Description

  • The 49 series operated regulators are designed for high-pressure service and can be used on either on vapor or liquid applications. Their outlet pressure ranges from 3 to 135 psig.
  • High pressure regulators usually reduce tank pressure to an intermediate pressure for use by another regulator.
  • Note: Type 49 regulators do not have internal relief valves, so these regulators cannot be installed in fixed piping serving 0.5 appliance systems.
  • Type 492Hp regulator is an adjustable high pressure regulator with hand wheel adjustment.
  • Type 493Hp regulator is an adjustable high pressure regulator with wrench adjustment and 3 spring ranges from 3 to 100 psig.
  • Type 494Hp regulator is a fixed high pressure regulator with no field adjustment. It is very compact.
  • Type 495Hp regulator is an adjustable high pressure regulator with a dial cap adjustment. This cap eliminates the need for a gauge on portable applications.
  • All types are equipped with a ¼” FNPT side outlet which is normally plugged and provides an opening for an outlet pressure gauge.
