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
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
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
