Mark 86Steam Tracing Regulators

The Mark 86 Ambitemp Regulator is designed to con-trol steam tracing lines based on ambient temperatures.These steam tracing lines are commonly used to pro-tect outdoor instrumentation, pipelines and tanks fromfreezing. The Mark 86 allows steam to flow through thetracer lines only when it is needed, and remains closedwhen the ambient temperature rises above a predeter-mined set point.

SEALED WELDED ACTUATOR (SWA)

The MK86, like our other self-acting temperature regu-lators, utilizes both Jordan’s sliding gate seat designand Jordan’s seal-welded actuator. The sealed weldedactuator (SWA) has no elastomer parts, and is utilizedfor its ability to provide longer lasting service. With allsteel construction, there are no parts that will wear outfrom temperature effects. Although it is made with thesame materials and design, the SWA on the Mark 86 isdifferent from our standard sealed welded actuator. OurJordan temperature regulators have an SWA that con-sists of bulb, capillary and diaphragm assembly. Asthe ambitemp valve is only sensing the ambient tem-perature, the sensing bulb and capillary are eliminatedfrom the construction.

The Mark 86 is generally installed as a normally closedvalve. As the ambient temperature falls below the setpoint, the valve will open, allowing steam to enter thetracing line system. The Mark 86 may also be set upas a normally open valve and stroke toward closed asthe ambient temperature rises.
