Siemens Combustion Controls VKO Oil Flow Control Valve

VKO series modulating oil valves control the flow of #2 oil, #4 oil,  #6 oil, or liquid propane.  Valves are positioned using either a crank arm kit or rotary actuator. VKO series oil valves are not intended for use as shutoff valves.  The valve body contains (2) identical female pipe threads for an oil tight seal with NPT piping.

VKO Oil Flow Control Valve Features:

  • UL listed for use with #2 oil
  • Up to 500 psi static pressure
  • Up to 500 psi differential pressure
  • Low leakage rate at full closed position
  • Corrosion-resistant for outdoor applications
  • Clear position indication on a laser-etched, anodized dial
  • Crank arm kits available for linkage applications
  • Valve actuator assemblies available

A Quick Comparison of Flow Meters for Industry and the Case for Thermal Mass Flow Meters

Engineers and facility managers seeking an air or gas flow measurement solution face a daunting array of technological options when researching and selecting flow meters. There are two basic categories: volumetric flow and thermal mass flow. Flow meters fall into one of these two groups. 

This video will help you choose the best technology for your industrial gas flow measuring application.

Optimize Process Performance with Precise Airflow Measurement from Air Monitor

Precise Airflow Measurement from Air Monitor

To improve efficiency and achieve optimal process performance, various industrial equipment such as boilers, furnaces, regenerative thermal oxidizers (RTOs), burners must have an optimal air-to-fuel ratio. Measuring airflow is critical to determining this ratio and optimizing combustion. Over time, an optimized system will also result in lower maintenance costs. Plant managers rely on instrumentation such as Combustion Technology ad Air Monitor's expert application engineers to find the best solutions for improving combustion process efficiency. 

Applications Requiring Precise Measurement of Combustion Airflow:

Industrial Boilers and Package Boilers Fueled by Natural Gas 

Although natural gas processes burn cleaner than other fuel types, these boilers still encounter particulate-laden airflows and may be subject to emissions regulations when exhausting to the atmosphere. These boilers frequently lack accurate instrumentation for measuring air and natural gas combustion flow to optimize the air-to-fuel ratio. 

Power, Biomass, and Recovery Boilers 

Whatever fuel is used to power the boiler, measuring the airflow into the combustion chamber is required to calculate the ideal air-to-fuel ratio. A system that is either too lean or too rich causes performance or cost issues. Another cause for emissions problems is poor burner design or poor combustion in boilers. Stop dealing with underperforming boilers and fix the incomplete combustion with an Air Monitor airflow measurement solution. 

Heaters, Furnaces, Ovens, and Kilns

The industrial sector relies on heat from various sourced burner equipment to perform essential process functions, whether for ceramics and glass or annealing and de-binding. Fuel costs can become prohibitively expensive in some processes that necessitate incredibly high temperatures. Using airflow measurement devices to optimize the combustion of burner equipment will reduce operating costs by increasing efficiencies and improving emissions.



UL508 Industrial Panel Shop Serving The Pacific Northwest

UL508 Industrial Panel

In any manufacturing business, industrial control systems are critical. According to Underwriters Laboratories (UL), an industrial control panel is a combination of two or more components of industrial control equipment.  A consistent and systematic arrangement of various features such as logic, process, overload relays, motor, circuit breakers, fused disconnect switches, pushbutton stations, timers, switches, terminal blocks, and pilot lights makes up an industrial control panel.   Related control circuit components, such as cabling and interconnection with other systems, regulate plant operations with little or no human intervention in a larger process control environment.

In the United States, UL 508A is the technical standard for Industrial Control Panels and is directs the design and construction of the industrial control panel. UL 508A control panels enable industrial systems to achieve data security while also preventing electrical risks. Electrical inspectors look for this mark as proof of third-party certification. Municipalities, government agencies, regulating bodies, and the panel purchaser all care about this. It's a symbol that demonstrates the panel's adherence to approved safety requirements. Engineers certified following the UL 508A standard advise their clients on how to create UL-compliant products. They also collaborate with them to create a worldwide design that eliminates the need for unnecessary or less-safe variations.

Combustion Technology, LLC is a UL508 approved panel designer and fabricator serving the Pacific Northwestern United states.
