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 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
Ratio Regulator FAQ
What is a ratio regulator? You might be more familiar with another name. These are sometimes called cross-connected regulators, proportional regulators, or zero governors. Or any mix of those words, like proportional governor. Each of these names can give us an idea of what the device does. When working with combustion, you want a specific Read More
FAQ: Gas Filters
A gas filter is installed upstream of all other components on an industrial combustion system. It’s a simple item with a big job. What does a gas filter do? A gas filter is commonly provided with a cast aluminum housing, and the filtration is performed by the media inside. Depending on your application and the 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
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
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
FAQ: What Does an Actuator Do?
What does an actuator do? An actuator drives a valve, causing it to move toward the open or closed positions. Actuators are present in all automatic valves, and can take the form of a motor (servo, pneumatic, hydraulic, etc), a solenoid, or something else. With a manual valve, your hand is the actuator. Actuators operate Read More
Rotating a DIN Plug
If you’ve never worked with plug-and-socket electrical connections, you might have a lot of questions the first time you see one. What’s the torque spec. for tightening the plug? How important is the gasket? How do I reorient the direction of the plug? Our latest video tackles the last question. Reorienting the socket is very 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
