The table below lists the correction factors for some of the more common gases: To determine the capacity of the B34S for gases other than natural gas, it will be necessary to multiply the values within the capacity tables by a correction factor. The B34S may be used to control gases other than natural gas. The 1' internal relief valve provides exceptional relief capacityĬorrection factors for non-natural gas applications: < B34SR The B34SR is the internal relief (R) version of the B34S series regulator. This model can be used on mid-range applications where an internal relief, or other type of over-pressure protection device is not required. < B34SN The B34SN is a spring loaded self-operated regulator with no internal relief (N) valve. All critical parts are either steel or aluminum, not plastic, to ensure reliability. Among its attributes are an adjustable loading ring for controlled boost at high flows, precision breather opening to ensure proper stability under all conditions, and in the R model, a high capacity internal relief valve. It combines the B31 8' diaphragm case with the B34 valve assembly for an economical solution to mid-range commercial and industrial applications. The B34S is a spring-loaded self-operated regulator available with or without internal relief. Field interchangeable adjustment spring.Spring loaded internal relief valve assembly.Zinc with dichromate plated steel lever.Molded diaphragm consisting of Buna-N and nylon.The rapid response of the B34S is particularly well-suited for midrange applications where quick on/off loads cause shock problems. < Economical < Space-saving design < Protects equipment from shock damage < Commercial performance in a compact sizeĪppropriate for many commercial and industrial uses such as gas engines, burners, furnaces, and boilers.
