Yarway Narvik HT- Templow Probe Style, High Temperature
The TempLowHT utilizes the fundamental design concepts of the standard Templow, designed for temperatures up to 621°C.
The TempLowHT is designed to eliminate sliding trim parts in the hot zone

  • Installation in straight, vertical or horizontal pipe.
  • Minimal headroom is required for mounting
  • Standard connections to ASME B16.5
  • Rapid evaporation of water is achieved to minimize the accumulation of water in the line.
  • Control within 10°F (6°C) of saturation is possible.
  • Water turndown capacity of 50:1 (typically) or higher is available.
  • Forged body with, stainless steel internals eliminates corrosion and vibration issues.
  • Inconel 718 nozzles minimize wear.
  • Replaceable Stellite® or 17% Cr seat for long life tight shut-off.
  • Long trim life. Pressure drop is taken across the nozzles rather than the seating surfaces.
  • Injection probe unscrews from body for easy capacity changes without changing stem/disc or seat.
  • Actual performance depends on the application and in many instances may exceed the design characteristics above.
