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
FAQ: How do you wire devices with metric electrical connections?
Conduit For many years, the use of rigid or liquid-tight conduit was the standard for running wires to field devices, such as safety shut-off valves, pressure switches, and flame safety devices. Rigid conduit is thin walled metal tubing that helps to protect wires from mechanical damage and some environmental factors. Liquid-tight conduit is flexible and 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
New Combustion Pressure Switch Accessories!
We’re excited to announce our all-new accessories for the C911-P combustion pressure switch are in stock and available now! What’s new? The electrical connection for the C911-P is M18x1.5. This might be an unusual size for some of you, so we are now stocking a cable gland that may be purchased separately if needed (pictured 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 is a Package Burner?
A package burner is an industrial burner with its own dedicated blower. The standard scope of supply includes everything you need to safely run the burner: blower, air valve, air pressure switches, gas manifold (with filter, pressure reducing regulator, safety shut-off valves, gas pressure switches, etc.), ignition transformer, and flame safety. You are responsible for Read More
FAQ: What is NFPA86?
If you work in combustion, then you’ve almost certainly heard the term NFPA86 before. Many people seem unsure about what exactly NFPA86 is. So, we’ve put together a handy overview to clarify this commonly heard phrase. NFPA NFPA is an organization (NFPA= National Fire Protection Association). Their goal is to reduce the threat of injury Read More
FAQ: What Does a Pressure Reducing Regulator Do?
Ever wondered what a gas pressure regulator is, or why you need it in your system? We’ve put together this FAQ to help answer your questions! What is a gas regulator? A regulator is a valve with the job of regulating system pressure. In industrial combustion, the two types of regulators we see most often Read More
FAQ: What are Needle Valves?
We often get questions about needle valves. So, we’ve put together this handy FAQ to help answer your questions! Needle valves, also called adjusting valves, or fine-adjusting valves, are usually found downstream of the safety shut-off valves (SSOVs) on the burner gas train, though they can also be found on the burner air train.
