Thermostatic steam traps reduce start-up times and improve overall efficiency. Balanced Pressure Thermostatic Traps use a special bellows diaphragm. The diaphragm is designed to open in response to pressure and temperature to discharge air and condensate, and to close against passage of steam. The temperature at which a Thermostatic Trap opens is variable, but is 10 to 30 deg F below saturated steam temperature for the existing pressure. This type of trap is small, simple in construction, size and weight, and has adequate capacity for various applications, especially in low-pressure heating systems.

  • Subcooling for extremely efficient system operation and elimination of flash steam losses on low pressure systems
  • Replaceable Dura-Stat® module
  • Resistant to moderate water hammer and chemical attack
  • Stainless steel components
  • Normally open at start-up to provide fast air venting
  • Follows steam saturation curve to operate over wide range of conditions
  • Compact size reduces installation space requirements
  • Self-draining, energy efficient
  • Fast response to changing conditions
  • Fail mode is open
  • Water hammer can damage bellows
  • Superheat can damage bellows if it exceeds trap temperature rating
  • Cooling leg required in some applications
  • 3-year limited warranty
