The 1267 Air Filter Regulator is designed for air or
gas service. Maximum allowable inlet pressure is
250 psi (17 bar). Operating temperatures are 0°F
to 160°F (-18°C to 71°C). The 1267AFR has low
capacity internal relief which provides very limited
downstream overpressure protection.

The internal relief valve in the 1267AFR does
not provide full overpressure protection and
is designed for minor seat leakage only. To
avoid exceeding outlet pressure limits in
service, a pressure-relieving or pressure-
limiting device should be provided. Leakage,
equipment damage, or personal injury can
result from over-pressuring the regulator.
All SOR instructions, as well as applicable local, state, and federal codes
and regulations should be adhered to when performing installation,
operation, or maintenance of a regulator. Personal injury, equipment
damage, or leakage can occur if the regulator is over-pressured or physically
damaged. To avoid physical damage the regulator should be installed in a
safe location. The regulator shouldn’t be installed in systems that exceed
the specifi ed pressure limit of 250 psi (17 bar). If leakage develops, then
maintenance is required. Failure to remove the regulator from service
immediately may create a hazardous situation.
