The Mustang® Joule-Thomson Regulator (MJTR) is a four-stage pressure regulator designed to compensate for Joule-Thomson cooling during sample extraction.  With a ratio controlled multi-piston design, the MJTR ensures the first three stages are always functional, even with fluctuations to the inlet pressure.

Application

The MJTR can be utilized in any application requiring multi-stage pressure regulation for sample conditioning or calibration gas cylinders.  An MJTR, located downstream of a sample probe, permits a 4-stage reduction in pressure without distorting the composition of a vapor sample.

When used in combination with insertion probes, the MJTR provides the most practical method for conforming to the API 14.1 and GPA 2166 standards.
