Through our discussions regarding equipment selection, you’ve learned that pulse-fire requires solenoid valves with extremely high operating cycles, burners that light reliably, and some method of impulse control. Through dozens of installations, our technicians have encountered and overcome a number of additional pitfalls, which can derail even the best planned system. Oversized Burners A common Read More

Pulse-fire 101 — Pulse-fire Implementation
Now that you’re familiar with the history, ideas, and benefits of pulse-fire, it’s time to look at implementation. Knowing what you do about the demands that pulse-firing exacts upon components, you want to make sure to get the most for your money, so you don’t wind-up spending your fuel savings on replacements. VMR, VML, VMM Read More
Pulse-fire 101 – Pulse-fire Equipment
Not all combustion equipment is suitable for pulse-firing. Some of the key equipment requirements for a successful pulse-fire installation include: operating cycles in excess of one million, capability of three cycles per minute, and repeatability. Solenoid Valve Operating Cycles In traditional, modulating systems, gas solenoids open during start-up and remain open during furnace operation. Unless Read More
Elektrogas VMRNA Automatic Vent Valve
The Elektrogas VMRNA is a normally-open vent valve for industrial combustion systems. Because the valve is open when de-energized, VMRNA can be thought of as the opposite of a safety shut-off valve (closed when de-energized). How they work A reverse-acting solenoid valve, VMRNA is normally open. That means you must apply power to close the Read More
FAQ: What’s an Air Valve?
The term “air valve” can refer to several distinct pieces of equipment. Combustion requires heat, fuel, and oxygen, and we usually see oxygen provided as a component of ambient air (the air we breathe). The type and quantity of air valves on a system is determined by the application and the control scheme. We might Read More
Elektrogas Solenoid Air Valves
Elektrogas VRA, VLA, and VTA are a series of solenoid actuated valves used to control cold combustion air. Thanks to their expert design, they’re capable of continuous service, and are ideal for on/off or high/low control of combustion air in industrial gas burners. Function Elektrogas air valves are normally closed. When powered, the valve opens Read More
Elektrogas SSOV Spare Parts
Are spare parts available for Elektrogas safety shut-off valves (SSOVs)? Absolutely! Don’t scrap that valve just yet. We stock a full range of spare parts for Elektrogas SSOVs, so please check with us first. We’ve compiled a list of the most common spares. Have a look! Dampeners The VML is a slow opening SSOV. The Read More
FAQ What is a Safety Shut-off Valve?
Q: What is a safety shut off valve? A: A safety shut-off valve (SSOV) is a normally closed valve which opens when power is supplied. They are found in the main gas train as well as the burner (gas) train. In a combustion system, safety shut-off valves receive their power from the flame safety device Read More
Elektrogas VMM Double Solenoid Valve
Elektrogas VMM solenoid valves are safety devices used to stop the flow of gas in a combustion system. The VMM features two separate solenoid valves in one unit. The first valve is fast opening; when powered, the valve rapidly opens against the strength of the gas flow. When de-energized, the valve closes, pushing on a Read More
Elektrogas Safety Shut-off Valve FAQs
Elektrogas safety shut-off valves (SSOVs) are some of the most popular items we carry, and customers often have many questions about them. We thought it would be helpful to create a list of commonly asked questions about these valves. Approvals Q: Are the VMR, VML, and VMM valve models “worldwide” valves? A: Elektrogas SSOVs are Read More
