 Temperature Control Valves > Mark 86 Series



MK86 Series The Mark 86 Ambient Regulator is designed to control steam tracing lines based on ambient temperatures. These steam tracing lines are commonly used to protect outdoor instrumentation, pipelines and tanks from freezing. The Mark 86 allows steam to flow through the tracer lines only when it is needed, and remains closed when the ambient temperature rises above a predetermined set point.

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