Bulletin 71.2:299H Specifications Specifications for 299H Series constructions are given below. Some specifications for a given regulator as it originally comes from the factory are stamped on a nameplate located on the actuator upper casing. Available Constructions Type 299H: Pilot-operated pressure reducing regulator with a pilot integrally mounted to the actuator casing. Type 299HR: A Type 299H with a token internal relief valve to relieve minor overpressure caused by thermal expansion.
Bulletin 71.2:299H 3/4 NPT CONTROL LINE W7527-1 W7528-1 TYPE 299H WITH EXTERNAL REGISTRATION TYPE 299HR PILOT WITH OPTIONAL TOKEN RELIEF Figure 2. 299H Series Sectional Views Features • Compact in Size—Small envelope because of the built-in pilot and internal registration. • Unique No Bleed Monitor System—Flexible worker/monitor system setup that allows for bleed to be piped to the intermediate piping thus eliminating downstream bleed which reduces lost and unaccounted for gas.
Bulletin 71.2:299H Introduction Principle of Operation Description Letter keys in this section refer to Figure 3 unless otherwise noted. Fast response and accuracy are made possible by the amplifying effect of the pilot and by the two-path control system. The function of the pilot is to sense change in the controlled outlet pressure and amplify it into a larger change in the loading pressure.

Bulletin 71.2:299H Wide-Open Monitor The control line of the upstream regulator is connected downstream of the second regulator (Figure 6), so that during normal operation the monitoring regulator is standing wide open with the reduction to distribution pressure being taken across the working regulator. Only in case of open failure of the working regulator does the wide-open monitoring regulator take control at its slightly higher setting.
