Understanding How Control Valves Work
Understanding industrial control valve design and operation is very important if you work as a process engineer, a plant maintenance person, or if you design process control loops.Control valves are used extensively in power plants, pulp and paper mills, chemical manufacturing, petro-chemical processing, HVAC and steam distribution systems.
There are many types, manufacturers, body styles, and specialized features, but the they all share some basics operating principles. The video below explains components, operation, and fundamentals.

Top 3 Reasons to Specify the Conval Clampseal Gate and Globe Valves
- Superior Rugged Construction - Conval valves are designed and built for extreme longevity. Features such as electroless nickel plated finish, complete material traceability of all wetted parts and yoke, instantly establish the quality of the Clampseal® Valve. The Clampseal® also has a pressure actuated backseat which provides maximum valve integrity by ensuring a positive internal stop for the valve stem and disc assembly. The actuated backseat extends packing life by securely isolating the packing from the pressure when the valve is fully open. Valves built forty years ago are still in service today.
- In-Line Renewability - When inspection or servicing is required, Conval's in-line renewable valves do not need to be cut out (as do most other welded-in valves). The result is the shortest downtime and lowest life-cycle costs in the industry. A complete service, including a reground seat, new packing or stem replacement can often be accomplished in less than thirty minutes.
- Renewal vs. Replacement - Renewing Clampseal® valves cost as little as 10% of the cost of replacing it. Renewing the packing is less than 4% of the cost of materials to replace a globe valve. In addition to the savings listed above, there are intangible savings from shorter shutdown time, which is considerable given that the cost of plant shutdown often exceeds the cost of equipment.
Happy New Year from PSI

Drexelbrook Total Tank Level System

| Drexelbrook Total Tank Level System |
Magnetostriction is one of many level technology options available to industrial users today. For liquid measurements, especially when a water interface exists, it unquestionably offers the most versatile and accurate solution on the market. Ametek now has an excellent solution to manage multiple variable measurements in storage tanks. Ametek Drexel Brook now offers the Total Tank Level Multi-variable Transmitter to measure both level and temperature with Modbus, 4 to 20 milliamp, and HART output capability.
The ability to measure and track various tank conditions in realtime is critical in today's process environments. The multi-variable capability of the Drexelbrook Total Tank Level System provides simultaneous data for total level, interface level, product temperature, water interface temperature total average temperature, and volume for all liquid components in the tank. Standard industrial level instruments utilizing guided wave capacitive or radar technologies provide 3 to 5 millimeter accuracy. Higher cost tank gauging technologies will provide 1 to 2 millimeter accuracy. Only magnetostrictive technology can provide superior sub 1 millimeter accuracy levels consistently under most process conditions. In addition, the Drexel Brook Total Tank Level System is fully compensated across the entire operating range of process temperatures, up to 257 degrees Fahrenheit.
One of the most challenging applications is the measurement of an interface level between two significantly different density liquids. The most common of these is oil and water. There are only a few technologies that claim to be able to make this measurement. Guided wave radar and magnetostriction are two of the most common. Guided wave radar technology is based on microwave pulses that are transmitted down a probe and are partly reflected by the product surface, as well as the interface level surface. In applications where both liquids have stabilized, guided wave radar technology can accurately determine both the product and interface level. If an emulsion layer forms between the two liquids this can significantly diminish the measured value, or even cause the complete loss of the signal. If this occurs, it is extremely difficult to maintain control of the process. Using a float based magnetostrictive technology, the measurement becomes straightforward. Both product and interface return signals are generated by the reflection of a magnetically induced strain on the measurement wire, which is embedded in the probe. Magnets are positioned on the probe based on their specific gravity matched to the liquids being measured. This ensures that the float will always maintain its position, both on the top liquid level, and at the interface position. The lower measurement signal remains unaffected by the formation of an emulsion. Comparing the two technologies clearly shows the advantage of magnetostrictive technology whenever emulsion layers are present. Guided wave radar can only be used to measure the overall level reliably under all conditions, while the Drexelbrook Total Tank Level System guarantees the continuous and accurate measurement of the overall level, and the interface, even under emulsion conditions.
The Drexelbrook Total Tank Level System easily integrates into existing control systems that have standard protocols, such as Modbus, 4 to 20 milliamp loop, or HART communications. Each instrument can beset up directly through the Ametek STExplorer software which can be downloaded free of charge. This makes installation and commissioning of the instrument easy. Drexelbrook's reliable magnetostrictive level probes have been installed in more than 100,000 systems worldwide. They are proven over years of grueling weather conditions and trusted by some of the largest companies in the world.
