Oil-fired boilers need a steady, accurately measured flow of oil to operate safely and efficiently. Fuel oil valves and actuators work together to regulate that flow, while also providing safeguards in case of a fire.

Fuel oil valves regulate the flow of oil into the burner. Actuators are used to control those valves, allowing the boiler’s monitoring and control system to adjust the fuel supply automatically based on demand. This automated control helps keep the boiler operating within spec, and at peak efficiency.

Some valves and actuators are mounted in one self-contained housing, while other configurations use separate valve and actuator assemblies that are joined by a linkage.

Many fuel oil valves feature a Proof of Closure (POC) switch as well that sends a signal back to the monitoring system to confirm valve closure, or provides visual confirmation that the valve is closed.

Fuel oil valves and actuators work together to modulate the boiler’s fuel oil supply based on demand. They are also responsible for shutting off the supply of oil during shutdown, and turning the supply back on during startup.

Many valves even feature a special heat-activated failsafe that keeps the valve open under spring pressure, closing it mechanically if the valve gets too warm.

When a fuel oil valve goes bad, it will either deliver too much or too little oil. Sometimes, none at all. This will make the boiler hard to start, and will cause it to produce either too much or too little steam based on its settings.

Things to Consider about fuel oil valves and actuators:Some fuel oil valves and actuators can be mounted in the same housing, functioning as a self-contained unit. Others are mounted as separate components joined by a linkage.Self-contained valve and actuator assemblies are easier to swap out, but harder to maintain and repair.Separate valve and actuator setups can be easier to repair and maintain, but may take longer to install.

A malfunctioning valve or actuator will cause the boiler to run too rich or too lean. It can also prevent proper startup. If you’re checking the valve, be sure to check the linkage and actuator, too. Loose linkage can cause the boiler to run out of spec.

Both are good solutions for operating a fuel oil valve safely. It just depends on how your monitoring and control system is set up, and whether it uses compressed air or electricity to power the actuator.
