1. DESCRIPTION
This installation and operation manual covers the Series VS1000 vaporizing, steam heated, single stage
pressure regulator. The VS1000 is primarily used to ensure that a sample of the process fluid is supplied
in the vapor phase at a regulated pressure to an analytical instrument. Steam flows through the inside of a
1/2 inch (12.7 mm) outside diameter tube inserted into the regulator body. Process fluid enters the body
and flows around the outside of the tube. Energy is transferred from the steam, though the tube walls, to
the process fluid. The steam is isolated from the process fluid by the tube wall. The process fluid is then
regulated to a lower pressure—typically less than 100 psig (6.9 bar) to supply the analytical instrument.
Refer to the catalog data sheet or contact factory for a complete list of options and specifications. A
typical VS1000 regulator is shown in Figure 1.
