Armstrong’s SH-1700 Series Bimetallic Steam Traps operate in superheat conditions, by the effect that rising temperature has on the bimetallic elements.

HOW IT OPERATES:

• At start-up the valve is wide open allowing a large volume of non-condensables and cold condensate to be removed from the system
• When the trap reaches steam temperature, the bimetallic elements pull the valve into the seat closing the trap
• The valve remains closed until the bimetallic elements cool thus allowing the valve to crack open, vent the condensate and non-condensables, and then close again when steam temperature is reached

FEATURES & BENEFITS:

• Adjusts automatically to changing conditions
• Utilizes titanium valves and seats to ensure extremely long service life in harsh environments
• Forged chrome-moly steel construction with integral stainless steel strainer
• In-line repairable
• Stacked nickel-chrome bimetal operator with titanium valve and seat
• Operates on low load and superheat applications through its pressure/temperature range
