Probe Style, High Temperature (HT-Templow)

Boiler Control ValvesYarway

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

The TempLowHT utilizes the fundamental design concepts of the standard Templow, designed for temperatures up to 621°C (1150°F). The TempLowHT is designed to eliminate sliding trim parts in the hot zone, while providing the traditional integral probe style desuperheater with isolation (stop) and water proportioning (control) in response to a temperature feedback control signal. • High pressure, high temperature steam attemperation • Boiler superheater • Boiler reheater

  • Installation in straight, vertical or horizontal pipe.
  • Minimal headroom is required for mounting
  • Standard connections to ASME B16.5 Precision control of temperature
  • 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. Low maintenance
  • 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. Adaptable to changing needs
  • 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.
