Steam Traps for Subcooled Tracing – Models M22/TM22/TS22
Gallery
Operation
On initial start up the steam system, large amounts of cold condensate and air are present in the system. At this point the bimetallic strip of the delta element relaxes and fully opens the valve assembly to quickly expel the high volume of non-condensate gases and cold condensate through the discharge port.
As the element senses an increase in the condensate temperature the bimetal expands and raises the stem to modulate the flow. Just below the temperature of saturated steam the seat will close tightly to prevent live steam from discharging.
Application
Specifically developed to make use of the latent heat or steam and the sensible heat of condensate prior to discharge for services with differential pressures to 300 PSI. The TS22 features sealed stainless steel construction, while the M22 and TM22 are completely maintainable and include integral strainers.
