Regulators

B838 Commercial Regulator

The B838 Series regulators are designed to handle the increased gas flows of large orifice sizes. With twin, large size diaphragm cases the 838 offers unusually large internal relief capacity for greater safety. It provides pounds-to-pounds and pounds-to-inches water column pressure regulation.

More Details

B531 Commercial Regulator

The Series B531 is a spring-loaded regulator equipped with a valve body that is effectively two regulators in parallel. This design allows for nearly double the capacity that can be achieved with a single 6 diaphragm regulator. The B531 design is symmetric about that downstream piping so all parts are identical in both diaphragm cases.

More Details

B57 Residential Regulator

The B57 regulator is ideally suited for use where inches of water column or pounds delivery pressure are desired for uses including utility services, small boilers, and other similar applications. The B57 is ideal for situations where rapid response is required, such as on/off loads, and can be utilized to avoid shock problems. In situations where complete 360 degree rotation of the diaphragm case is desired, the B57 can accommodate any position needed.

More Details

B42 Residential Regulator

The B42 is a spring loaded self-operated regulator with internal relief option. The B42 features a molded diaphragm, 6:1 lever ratio and a one inch vent. The benefit is a lighter more compact unit that provides the power, capacity and relief performance of larger regulators.

More Details

B38 Commercial & Industrial Regulator

Appropriate for large capacity commercial and industrial uses where inches of water column or pounds delivery is desired such as utility services, gas engines, burner trains, furnaces, and boilers. The rapid response of the B38 is particularly well suited for applications where sudden on/off loads could cause shock problems.

More Details

B34 Commercial & Industrial Regulator

The B34 is appropriate for many commercial and industrial uses such as gas engines, burners, furnaces, and boilers. The rapid response of the B34 is particularly well-suited for mid-range applications where quick on/off loads cause shock problems.

More Details

B31 Residential Light Commercial & Industrial Regulator

The B31 is used where inches of water column or pounds delivery is desired such as utility services, and small-to-medium sized furnaces and boilers. The rapid response of the B31 is particularly well suited for applications where sudden on/off loads could cause shock problems.

CL838 Regulator

Twin Parallel Flow Dual Pilot-Loaded Regulator. The construction of the main regulator in the CL838 is the same as a standard B838 service regulator except the main springs are installed to close the valve. This main regulator is the same in either the CL838-1 or CL838-2 models. Your selection of either model 1 or model 2 will be determined by the outlet pressure range of the pilot regulators.

More Details

CL231 Regulator

The CL231 regulator is designed primarily for use in medium size commercial and industrial installations requiring highly accurate pressure regulation. The CL231 can produce substantial savings for users in lower initial costs, lower installation costs, and lower maintenance costs.

More Details

CL38 Regulator

The CL38 is a constant pressure loaded regulator for use where closer PSIG-to-PSIG regulation is desired than can be obtained from conventional spring-loaded regulators. Since this regulator requires an inlet pressure supply of only 1/2 PSIG above outlet pressure, this unit can be used where demand type loading will not meet the low pressure differential.

More Details

CL34 Regulator

The CL34 is appropriate for commercial and industrial applications where very accurate pressure control is required such as “fixed-factor” metering applications or large boiler and furnace applications.

More Details

CL31 Regulator

The CL31 was designed for systems requiring highly accurate pressure regulation such as: utility Fixed Factor metering of relatively small loads (up to 4000scfh)and industrial heating equipment requiring constant high burner pressures (1 PSIG to 20 PSIG)
