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?
Categories: Butterfly Valves, Elektrogas, Industrial Solenoid Valves, Industrial Valves
Comments Off on 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?
Categories: Butterfly Valves, Elektrogas, FAQs
Comments Off on 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
FAQ: What are Low NOx Burners?
Categories: FAQs, Industrial Burners
Comments Off on FAQ: What are Low NOx Burners?
What is NOx? Nitrogen Oxide (NOx), is a common byproduct of combustion processes. Whenever fuel (natural gas, propane gas, methane, coke oven gas, biogas, etc) is burned at high heat, NOx is produced. It is present in emissions from cars, trucks, boats, planes, and construction equipment, as well as industrial equipment like power plants, kilns, Read More
