Precision Control for Asphalt Plant Fuel Oil Flow
Accurate fuel-oil flow control is critical to reliable asphalt plant performance. The Hauck/Honeywell Micro-Cam Oil Valve (MCOV Series) is engineered for precise fuel oil metering in burner systems and industrial applications. Built to handle demanding operating conditions, this valve delivers dependable control and repeatable performance, making it a trusted choice for asphalt plants and other heavy-duty combustion systems.
Micro-Cam Oil Valve – Product Information
The Micro-Cam Oil Valve (series B, F, G & K) is engineered for accurate fuel oil flow metering rather than full-shut-off service. Key features include:
- Designed for repeatable, smooth control of fuel oil flow – ideal for modulating burners and precision fuel trains.
- Manufactured with durable materials: robust steel body, heat-tempered internals, and a self-cleaning mechanism to maintain performance in tough oil service.
- Flexible actuation options: manual linkage, direct-mounted actuators, or automated control systems for integration with your burner controls.
- Works with a variety of fuel oil grades (including pre-heated heavier oils when used appropriately).
- Note: This valve is designed for flow control and should be combined with a shut-off valve, either upstream or downstream, to achieve full shut-off functionality.

Application in Asphalt Plant Environments
In an asphalt plant setting, consistent fuel-oil flow is essential for burner stability, drum temperature control, and overall production consistency. The Hauck Micro-Cam Oil Valve supports these goals by offering:
- Precise oil flow metering for drum burners, pre-heaters or hot-oil heaters.
- Compatibility with fuel-oil systems common in asphalt production.
- Retrofit-friendly design—allowing upgrades of existing control valves with minimal disruption.
- Integration capability for modulating control schemes that respond to production demands.
Sizing, Installation & Service Support
Motion Engineering not only supplies the hardware—you also get support to install and service it effectively:
- Sizing support – We can help determine which series (B, F, G, or K) best fits your capacity, oil supply pressure, viscosity, and flow requirements.
- Installation guidance – Proper orientation, actuator coupling, linkage setup, and fuel-oil pre-heating/viscosity considerations all matter.
- Service & parts – Access to manuals, maintenance recommendations, and parts kits from Honeywell to keep your valve running at peak performance.
