DM6/DM12
DS12
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
A line of lightweight, yet rugged steam traps that provide modulating discharge of light condensate loads without the loss of live steam. These traps feature energy-efficient operation with excellent start up capacities for services with differential pressures up to 150 PSI. The DS12 features sealed stainless steel construction while the DM6/DM12 are fully maintainable.
