from external sources or from debris in the gas line.

The regulator should be inspected for damage after

any overpressure condition. Complete instructions for

installation, operation, and maintenance are provided

with each regulator.

Capacity Data

Flow capacities for various inlet pressures and

outlet pressure settings are shown in Tables 3 to 10.

Capacities are in thousands of SCFH at 60°F and

14.7 psia and in thousands of Nm

/h at 0°C and

1.01325barof0.6specicgravitygas.Toconvert

to equivalent capacities of other gases, multiply the

SCFH values shown by the appropriate factor: air–

0.775; propane–0.628; butane–0.548; nitrogen–0.789.

Forgasesofotherspecicgravities,multiplythegiven

capacity by 0.775, and divide by the square root of

theappropriatespecicgravity.Then,ifcapacityis

desired in Nm³/h at 0°C and 1.01325 bar, multiply

SCFH by 0.0268.

Note

For optimum performance, select the

lowest spring range that includes the

desired outlet pressure setting.

1. Pressure ranges shown are correct if the regulator is installed with the actuator portion above the body portion. If the regulator is installed with the actuator portion below the body, the

pressure ranges will be lowered by approximately 2 inches w.c. / 5 mbar for the Type 133L and by approximately 3 inches w.c. / 7 mbar for the Types 133H and 133Z.

2. If the 2 inches w.c. / 5 mbar to 2 psig / 0.14 bar springs (all 6 ranges) are used in the Type 133H, the pressure ranges will increase by approximately 1 inch w.c. / 2 mbar due to

the weight of the Type 133H parts (assuming that the actuator is installed above the body).
