Check Valve Incorporates Useful Features For Industrial Process Fluid Systems

A check valve allows fluid flow in one direction (forward) and prevents it in another. They are employed extensively in industrial and commercial piping systems to prevent the reverse flow of a fluid that would produce an undesirable effect. Numerous sizes and types are available to meet specific application challenges. Each check valve must be properly selected to accommodate the pressure, temperature, and flow characteristics of each system. Proper materials of construction must be selected to provide suitable service with the process media.

Check valves are commonly applied to protect pumps from any induced reverse flow in a system. They can also be found in combination with other valves, providing assurance that the process fluid flows only in one direction.

One manufacturer, Titan Flow Control, incorporates a number of features into a single unit to provide wide ranging application. Features of the check valve are detailed below, along with a data sheet with more technical information. You can always get the latest available product data and solid application assistance from the process control specialists at Mountain States Engineering. Combining your process knowledge with their product application expertise will yield a positive outcome.


Understanding Condensate Pumps on a Steam Distribution System

condensate pump is a specialized device intended for use in transferring condensate (water) produced in an industrial steam system. Condensate from a heating system or process is collected, then pumped to the condensate return system, where it is routed back to the boiler for reuse.

In certain cases, the steam pressure of the system may be sufficient to push the condensate through the steam traps and condensate return lines, back to the condensate holding tank in the boiler room. In most practical situations, however, one or more condensate return pumps are required to assist in overcoming gravity, pressure drops from long piping runs, and back pressure in return lines.

Condensate Return Pumps are either electrically-driven centrifugal pumps or non-electric mechanical pumps that use steam pressure as the motive force to pump the condensate. Non-electric pumps are referred to as Pressure Motive Pumps (PMPs).

A facility will often have a separate area that contains various components required for the generation of steam, such as a boiler, condensate holding or deaerator (DA) tank, boiler feed pump, water treatment, etc. Regulated by the boiler control system, the boiler feed pump sends condensate from the holding tank back to the boiler.

Pressure Motive Pumps (PMPs) are non-electric pumps which return condensate back to the boiler room; using steam pressure as the motive force. PMPs can be supplied as stand-alone units – which include a pump tank, the internal operating mechanism, and a set of inlet and outlet check valves, or: as a packaged system – which also includes the vented receiver tank (to collect the condensate) mounted on a common base.

The following is a comprehensive document, courtesy of Watson McDaniel, that provides a good general understanding of steam and condensate systems, traps and condensate pumps.

Shell and Tube Heat Exchanger
Shell and tube heat exchanges are found throughout fluid based industrial process control operations where heat must be transferred between two closed fluid systems. There are numerous design variants intended to provide levels of performance tailored to specific process requirements.

Provided below is a white paper that illustrates and explains the fundamentals of heat exchanger performance for shell and tube units. Covered are the three modes of heat transfer: conduction, convection, and radiation. Three sample application cases are covered, showing how the formulas are applied, and illustrations provide for even better understanding of basic operating principals. The article is sure to refresh or enhance your heat exchanger knowledge.

MSEC brings many years of heat exchanger application experience to bear on your application requirements. Share your new or drop-in replacement heat exchanger challenges with MSEC and work toward the best installed solution.

Simple BTU Metering For Commercial and Industrial Applications

cooling system
Monitoring thermal energy usage at logical or localized points of consumption can provide a manager some insight into the real costs of process or space operation, as well as where the greatest benefits may be reaped from efforts at maximizing energy efficiency.

Heating and cooling systems or loops that employ water as the heat transfer medium can be simply and economically metered to determine the thermal energy usage of a space or process. The simple setup consists of a flow meter, two temperature sensors, and a calculating module that collects the output from all three devices and produces a summation of the total heat transferred through the system portion served by the subject piping. This arrangement is commonly called BTU Metering.

The size of the system being metered may be an important factor in determining the most effective metering equipment specification. A larger capacity fluid system is likely to benefit from highly accurate measurement equipment, since inaccuracy in temperature or flow measurement is leveraged by the large amount of liquid moving through the system. Heating or cooling systems of small or moderate size tend to be well suited for the application of moderate to good accuracy metering equipment, with its substantially reduced cost of installation and ownership. The key to success is selecting equipment that is well applied for the whole range of anticipated flow rates and temperatures.

If your building, plant, or process currently does not have any thermal metering, the installation of this simple device can provide information that assists in making significant progress in building an energy saving plan. More information is available from product application specialists, as well as consultation on how to most economically accomplish your process energy metering goals. Share your process measurement and control challenges with a product specialist and work together to develop effective and sensible solutions.
