299H Series
2
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 299HSR:
Same as the Type 299HS with an
internal token relief valve.

Options
• Filter
(3)
:
A P590 Series filter installed in the pilot
supply tubing between main body and pilot
• Filtered pilot supply regulator
(3)(4)
:
A Type 67CF
supply regulator with integral 5 micron
Polyethylene filter
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 inches 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 and 299HSR.
