1. Damage to internal parts of the regulator may occur if outlet pressure exceeds the actual pressure setting by amounts greater than those shown in this column.
2. For outlet pressure settings to 25 psig / 1.72 bar only. For pressure settings over 25 psig / 1.72 bar, outlet pressure is limited by maximum emergency outlet pressure of 45 psig / 3.10 bar.
3. For outlet pressure settings to 350 psig / 24.1 bar only. For pressure settings over 350 psig / 24.1 bar, outlet pressure is limited by maximum emergency outlet pressure of 550 psig / 37.9 bar.
4. Leakage or bursting of pressure-containing parts may occur if outlet pressure exceeds these values.

1. Leakage or bursting of pressure-containing parts may occur if inlet pressure exceeds these values.
To avoid overpressure, provide an
appropriate overpressure protection
device to ensure that none of the limits
listed in Specications section, Tables 1
through 3 will be exceeded.
Regulator or relief valve operation below the limits
specied in Specications section, Tables 1 through 3
does not preclude the possibility of damage from external
sources or from debris in the gas line. Inspect the
regulator for damage after any overpressure condition.
Startup
Starting up the unit consists of opening the upstream
block valve, introducing gas pressure. Use gauges to
monitor pressures during startup.
The range of allowable pressure settings is marked
on the nameplate. If a pressure setting beyond the
nameplate range is required, substitute an appropriate
spring selected from Table 5. Be sure to change the
nameplate to indicate the new pressure range.

Note: Maximum inlet pressure not exceeded 1500 psig / 103 bar.
1. Inlet pressure must not exceed the sum of the actual outlet pressure setting and the maximum allowable pressure drop. For example, with an outlet pressure setting of 200 psig / 13.8 bar
and a 3/8 in. / 9.5 mm orice with a maximum allowable pressure drop of 500 psid / 34.5 bar d, the maximum inlet pressure is 700 psig / 48.3 bar.
2. Nitrile (NBR) valve disks are normally furnished for pressure drops to 200 psi / 13.8 bar, differential. For better erosion resistance, Nylon (PA) valve disks are normally furnished for
higher pressure drops. Some erosion of valve disks occurs at all pressure drops due to solid particles in the ow stream. The rate of erosion is higher with large amounts of impurities in the
ow stream and with high pressure drops. Valve disks and other regulator parts must be inspected periodically for erosion and damage and must be replaced as necessary.
