In this installment of Ask The Experts, noted process control authority and CONTROL Columnist Béla Lipták and his cadre of automation experts answer a reader s question regarding control valves for ...

Control valves are expensive high-tech products. The final selection and design should be left to experts, such as the valve manufacturer’s engineers, who can perform a complete system analysis that ...

Built-in Process Sensors (P1, P2 and Temperature) substantially reduce process lag over control systems, resulting in enormous cost savings to the process. Microprocessor-Based Controller. Control ...

Process control systems are essential for optimizing the performance, safety, and quality of chemical processes. However, they can also malfunction or deviate from the desired set points, causing ...

History is a constant reminder that accidents and catastrophic events can and do occur in process environments. As processes become more complex (for instance, allowing for greater operating ...

Issues associated with control valves, such as dead band, actuator/positioner’s design, response time, valve type, and sizing, all have a huge impact on process flow. Extensive studies on control ...

While conventionally a control valve type is chosen so that process behaves linearly, non-linear compensation can alternatively be included in the control system. Known as output conditioning, this ...

RS offers an extensive selection of Festo process automation products engineered to improve efficiency, safety, productivity, profitability, and product ...

According to process control experts, a detailed and specific set of control valve requirements is more than necessary when it comes to good control loop performance. Control valve selection plays a ...

Failures on control valves often stop a part of the process or shutdown the whole plant if it occurs on critical systems. The detection of these failures is often dependent on operator supervision and ...
