Kromschroder PartsKromschroder Products

Elster Kromschröder is the primary brand stocked and sold by Combustion 911. No other brand on the market is as committed to safety, quality, and reliability, making Kromschröder the #1 choice of industry professionals and combustion technicians worldwide.

Kromschröder's commitment to safety is as progressive as the products they manufacture. Approvals are maintained to satisfy a broad range of national requirements, including UL, FM and CSA, which are those most commonly required for installations in North America. SIL ratings are now listed in the majority of product documents, preempting the future of safety ratings for combustible gas products in the US and abroad.

Kromschröder products are subjected to rigorous quality control standards, and all valves are tested prior to shipment, to help ensure proper operation upon arrival. Constant product innovation means that you remain at the forefront of the industry, and a commitment to product support and reverse compatibility allows you to keep your system running at peak performance for years before making the decision to upgrade to the latest platform.

Kromschröder products are among the most reliable money can buy. Valvario solenoid valves boast an extremely high operating cycle rating, something that is absolutely necessary for pulse-fire systems, in order to avoid constant, and costly replacements. Kromschröder controls, such as the BCU or IFS, typically run well beyond their life expectancies, but when replacements become necessary, most of the time this can be accomplished without rewiring. And Kromschröder burners are known throughout the industry for their ability to light reliably, time and again.

Combustion 911 specializes in Kromschröder equipment for the North American Market, though we can supply European Standard equipment as well. A wide variety of products are available to browse online, from pressure switches, pressure and ratio regulators, solenoid valves and gas filters, to BCU, PFU, IFD 258, and IFS 110 burner controls, as well as pilot and main burners. Also available online is a comprehensive library of the most up-to-date Kromschröder product literature available.

If you're in the market for Kromschröder products, whether it be for a new installation, a rebuild of a current furnace, to replace like items due to wear or to replace another manufacturer's equipment, our knowledgeable sales staff can help.

Kromschroder Valves

Butterfly Valves

BVG The butterfly valve BVG is designed to adjust volumes of gas, cold and hot air, and flue gas on various appliances and flue gas lines. The BVG is a butterfly valve with reduced nominal diameter (reduced by one or two nominal sizes) and can be used to achieve higher control accuracy. This will mean that complex reducing fittings will no longer be required.
BVH The butterfly valve BVH is designed to adjust volumes of gas, cold and hot air, and flue gas on various appliances and flue gas lines. The butterfly valve BVH is used for processes that require very precise adjustment of the flow rate or low leakage. In conjunction with the stop bar, the valve disc ensures very low leakage rates.
BVHM The butterfly valve BVHM is well suited to intermittent operation due to the large number of operating cycles in conjunction with the solenoid actuator MB 7.
BVHS The butterfly valve BVHS with safety closing function is used with the actuator IC 40 in systems where it is important that in the event of a main voltage failure, the valve closes preventing air streaming into the furnace without being under control.

Solenoid Valves

VAD The gas regulator with solenoid valve VAD with high control accuracy, is for excess air burners, atmospheric burners, or single-stage forced air burners. Pressure preset via setpoint spring.
VR VR solenoid air valves are for on/off or high/low control of air flow for combustion systems. Their continuous duty capability makes them especially well suited to withstand the continuous cycling of frequency firing combustion control systems.
VGP VGP solenoid valves are normally closed solenoid-operated valves for on/off control of natural gas, LP, clean biogas, and air flow. They are widely used as gas safety shut-off valves for industrial and commercial combustion systems.
