The Type 1227 High Flow Gas Pressure Regulator is used with natural gas, compressed air, and other gases.
Depending on the configured model, the maximum possible inlet pressure is 2000 psi (138 bar) and the
temperature limits are -40°F to 180°F (-40°C to 82°C). Please refer to the Type 1227 Product Specifications
section to determine your model's exact specifications. The application of your regulator should not exceed any
of the specified ratings.
The ControlAir Type 1227 Pressure Regulator does not include internal relief. A pressure
WARNING
relieving or pressure limiting device should be used to ensure that the outlet pressure
does not exceed the regulator's specifications while in service. Leakage, equipment
damage, or personal injury can result from over-pressuring the regulator.
NOTE: If you suspect that a product is defective, contact the factory or the ControlAir Representative in your area
for a return material authorization number (RMA). This product should only be installed by trained and competent
personnel.
All ControlAir instructions, as well as applicable local, state, and federal
WARNING
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 should not be installed in systems
that could exceed its specified pressure limits (as listed in Table 1).
If leakage develops, then immediate service is required. Failure to
remove the regulator from service immediately may create a
hazardous situation.
