1. Low Pressure Trip cannot be used with this main valve spring range for 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 pressures as an
externally registered Type VSX-2.
2. 70% of regulator setpoint is the minimum allowable Low Pressure Trip setting for an internally registered Type VSX-2 used with this main valve spring range. 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 pressures as an externally
registered Type VSX-2.
3. 75% of regulator setpoint is the minimum allowable Low Pressure Trip setting for an internally registered Type VSX-2 used with this main valve spring range. 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 pressures as an externally
registered Type VSX-2.
Note: Other spring combinations are available, please contact your local Sales Ofce for additional information.
