61R2 AND 496 REGULATORS

General InformationThe Model 61R2 and 496 Compact Regulator (CR) are designed to deliver reliable and safe regulation of

natural gas, air, nitrogen, carbon dioxide, propane and other non-corrosive gases for residential, light commercial and

light industrial applications. Outlet pressures between 3.5” and 2 lbs. are available. Operating temperature range is

-20 F to 150 F (-28.9 C to 65.5 C).

The diaphragm case is spring-loaded and easily removed for routine inspection without disturbing the line connection.

Both regulators have an internal relief valve designed to control the maximum allowable buildup of downstream pres-

sure. All models conform to ANSI code B109.4-1998 and CGA Service Type Regulator Specification CAN/CGA-6, 18-M95.

Corrosion ProtectionThe protective finish on all Global regulators resists corrosive effects of weather and harsh environments. This

greatly inhibits the oxidation of metal surfaces that may eventually compromise the integrity of the metal. A finish

enamel topcoat further protects the regulator.

Valve bodies may be coated with either yellow zinc chromate, clear zinc, or E-coat.

High Tensile Strength Valve BodiesEach Global regulator is equipped with a high tensile strength cast iron valve body that rotates 360 degrees.

The 496 regulator rotates in 90 degree increments.

Available body sizes for both Global regulators are: 3/4” x 3/4”, 3/4” x 1” and 1” x 1”.

The 61R2 is also available in sizes: 3/4” x 1 1/4”, 1” x 1 1/4”, 1 1/4” x 1 1/4”.

The 496 is also available in sizes: 3/8” x 3/8”, 1/2” x 1/2”.

ApplicationBoth models are equipped with an internal relief valve with passages designed to maximize the release of gas as

quickly and efficiently as possible. It is set to relieve at 7” to 10” W.C. above normal outlet pressure setting.

Both models are also equipped with an extra large, removable, insect-proof, stainless-steel, screened vent to resist

freeze-ups and to exclude foreign matter. The vent is threaded 3/4” or 1” NPT and is suitable for indoor installations.

OptionsThe regulator vent opening should face downward (6 o’clock) to minimize the chance of blockage from ice and snow.

If not, a plastic elbow vent with a protective screen may be screwed into the vent (Global part # 041-01092-001).

Other Options2 lb. Regulator Seal Wires Angle Body Large Body to 1 1/4” (61R2 only)

61R2 REGULATORDescription

The 61R2 has a 6-inch diaphragm that uses its large area to provide consistent regulation over a wide range

of flows. The 61R2 has been a staple of the gas industry for almost 40 years.

496 COMPACT REGULATORDescription

The 496 Compact Regulator (CR) uses a 4-inch molded, roll-out diaphragm to provide the capacity and relief

performance expected from larger regulators. The reduced size and weight makes for easier handling,

installation and reduced shipping charges.

61R2 REGULATOR CAPACITY PERFORMANCE

CAPACITY FOR OTHER GASESOur Regulators may be used for regulating other gases.

To determine flow capacities of other gases, multiply the

figures in the capacity table by the correction factors

listed in the following Table.

For determining capacities for other gases not listed in the table,

use the following relationship to calculate the correction factor. Correction Factor =
