299H Series

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.
Type 299HS: Same as the Type 299H
with a Type VSX-2 slam-shut valve which
provides overpressure or overpressure and
underpressure protection.
Type 299HV: Same as the Type 299H
with a Type VSX8 slam-shut valve which
provides overpressure or overpressure and
underpressure protection.
Type 299HSR: Same as the Type 299HS with an
internal token relief valve.
Type 299HVR: Same as the Type 299HV with an
internal token relief valve.

1. The pressure/temperature limits in this Instruction Manual and any applicable standard or code limitation should not be exceeded.
2. For optimum performance, a pilot supply regulator may be installed in the pilot supply tubing between the main valve and pilot.
3. A pilot supply regulator or a P590 Series filter (only one may be used, not both) may be ordered with the Type 299H, but not both.
4. For in. w.c., use a pilot supply regulator if actual inlet pressure varies more than ±20 psi / ±1.4 bar and published accuracy is required.
5. This orifice size is not available for Types 299HS, 299HV, 299HSR and 299HVR.
6. Product has passed Emerson testing for lockup, relief start-to-discharge and reseal down to -40°.
