Pipe Sizes ................................... 1” to 3” threaded connections with NPT or ISO7-1 threads. 4” 125 lb. ange (220J only).

Housing Material ....................... 220D, 220E, 220G, 220J: aluminum.

Mounting ................................... Mount in an upright position only.

NOTE: All Maxitrol gas pressure regulators should be installed and operated in accordance

with Maxitrol Safety Warning Instructions (see GPR_MI_EN.ES).

Gas Types ................................... Suitable for natural, manufactured, mixed gases, liqueed petroleum gases, and LP gas-air

mixtures.

Maximum Inlet Pressure ............ 10 psi (68.9 kPa)

Flow Rates .................................. up to 50,000 CFH (1416 m

/h)

Emergency Exposure Limits ........ 25 psi (170 kPa)

Ambient Temperature Ranges ..... -40 to 200°F (-40 to 93°C)

Sensing Taps ............................... Three positions can be tapped and plugged for measuring pressure. The fourth position is

used to supply inlet pressure to the pilot regulator.

Remote Sensing .......................... 220D, 220E, 220G models may be ordered with remote sensing. The internal sensing tube is

omitted and external sensing taps are provided. Add sufx letter “R” to model number when

ordering.

NOTE: 220D, 220E, 220G, 220J are not CSA certied.

NOTE: ”L” models available for outlet pressures under 1 psi (6.9 kPa).

The 220 series uses a servo-operated design rather than a

spring-loaded design and can deliver higher outlet pressures

than conventional spring-loaded models.

The main diaphragm of the model 220 is loaded with gas pressure

instead of spring pressure. A small pilot regulator, located in the

upper housing, accurately controls this gas pressure. When the

regulated outlet pressure of the servo regulator is changed by

spring adjustment, the outlet pressure of the 220 main regulator

will be changed proportionately. Applications include industrial

furnaces and ovens.
