SG2 = Specific gravity of the gas to be controlled.1 B34 Series Regulator Commercial and Industrial Regulator Appropriate for many commercial and industrial uses such as gas engines, burners, furnaces and boilers. SG1 = Specific gravity of the gas in which the capacity is published. To calculate the correction factor for gases not listed in the table above, use the gases specific gravity and insert it in the formula listed below: The table below lists the correction factors for some of the more common gases: To determine the capacity for gases other than natural gas, multiply the values within the capacity tables by a correction factor. The B34 may be used to control gases other than natural gas.

> Unmatched overpressure protection with internal monitor (IM) plus internal relief option > Large 12 diaphragm for better outlet pressure control > Wide range of valve body sizes including NPT and flange connections > Controlled size breather orifice eliminates pulsation and provides normal action at low flows > Field interchangeable adjustment spring > Spring-loaded internal relief valve assembly > B34MR The B34MR is the same as the B34MN, except it has internal relief similar to the B34R. The monitor regulator is set to take over control from the operating regulator with only a slight increase in outlet pressure. This series system assures maximum safety with uninterrupted service. Used in a series monitoring installation as the upstream regulator, this unit gives customers an operating device that assumes control over an operating regulator when failure is sensed by the control line of the monitor. > B34MN The B34MN is very similar to the B34DN with a closed throat, downstream control line and no internal relief capabilities, except for an O-ring seal on the valve body stem through the throat to assure positive downstream control when installed ahead of a downstream regulator. > B34DR The B34DR is the same as the B34DN, except it has internal relief similar to the B34R. Since the control point is no longer at the outlet of the valve body the regulator does not boost, but all the capacity tables are the same as the R and N models. This unit is used when it is desirable to control the regulator from points other than the valve outlet. > B34DN The B34DN is a standard B34N with a closed throat, downstream control tap on the bottom of the diaphragm case, and no internal relief capabilities. This model features an adjustable loading ring for controlled boost at higher flows and a 1 internal relief valve. > B34R The B34R is the internal relief version of the B34 series. This regulator can be used on low or intermediate inlet pressures where an internal relief or other type of over-pressure protection device is not required. > B34N The B34N is a spring loaded self-operated regulator with no internal relief, an adjustable loading ring for controlled boost at higher flows, and a precision breather opening to ensure proper stability for all conditions. The rapid response of the B34 is particularly well-suited for mid-range applications where quick on/off loads cause shock problems.

Appropriate for many commercial and industrial uses such as gas engines, burners, furnaces and boilers.
