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
How to: Attach S Actuators to VF Valves
It’s easy to mate an Elektrogas S actuator with a VF butterfly valve. Here’s how it’s done: Identifying the Parts To begin, let’s gather and identify the necessary parts. S actuators ship with the parts shown above. 1) The solenoid actuator 2) A connection ring3) Two screws4) A cork gasket Butterfly valve VF ships alone. Read More

ESA Complete Combustion Systems
Whatever your combustion needs, ESA offers complete combustion systems to help you reach your goals. Their focus is to give you the functions, controls, and productivity you need. ESA can help you reduce energy cost, lower emissions, and meet all necessary rules and regulations. They’re more than a burner manufacturer, though their product range and Read More
Elektrogas VS Pressure Relief Valve
The Elektrogas VS pressure relief valves reduce temporary pressure surges in combustion systems. These devices are usually used on gas trains, industrial applications, and gas firing systems. The shutting-off of automatic valves, or regulators not closing tightly, can cause pressure spikes. By releasing extra pressure in a relief line, Elektrogas VS valves enable systems to Read More
FAQ: What Are Butterfly Valves Used For?
Butterfly valves may be used to regulate, or control flow in combustion systems. The models found on our site allow some flow even when 100% closed. Butterfly valves can be found on both gas and air lines in combustion systems. The “butterfly” part of the name actually refers to the rotating disc connected to a 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 VMRNA Automatic Vent Valve
VMRNA from Elektrogas is a normally-open vent valve for industrial gas manifolds. This valve is suitable for discharging excess or leakage gas into relief lines, for venting to a safe location (or atmosphere). They function by means of a reverse solenoid valve. This means without power, the valve is open. An inner spring pushes on Read More
