1. See Table 3 for main valve spring number.
2. Other spring combinations are available, please contact your local Sales Of ce for additional information. Trip pressure that are 2 or 3 psig/ 0.14 to 0.21 bar over set pressure may result in
internal parts damage.
3. Regulator main valve spring numbers 2, 3, and 4 cannot be used with an internally registered Type VSX-2 to provide underpressure shutoff under owing conditions. If protection
against loss of inlet pressure is the only required function for the Type VSX-2 then an internally registered Type VSX-2 may be used with the same minimum trip pressure as an
externally registered Type VSX-2.
4. 50% of regulator setpoint is the minimum allowable underpressure shutoff setting for an internally registered Type VSX-2 used with main valve spring numbers 5, 6, 7, and 8. 70% of
regulator setpoint is the minimum allowable underpressure shutoff setting for an internally registered Type VSX-2 used with main valve spring number 9. If the protection against loss of inlet
pressure is the required function for the Type VSX-2 then an internally registered Type VSX-2 may be used with the same minimum trip pressure as an externally registered Type VSX-2.
