For any process where temperature needs to be monitored or controlled, a thermal loop is required. Typically, a process that contains a thermal loop includes some key elements: the process itself, the temperature sensor or transmitter, the temperature controller and the power controller. 

Positioner selection deserves due diligence and consideration of several factors before making any firm decision. Theres certainly not a typical one-size-fits-all approach for positioners; an uninformed choice can lead to undesirable consequences.

For a power plant to run as efficiently as possible, proper filtration is a critical part of the equation.

Appropriately specifying trip valves in the world of natural gas liquification is a critical element. Failing to do so effectively can risk the lives of operators and maintenance personnel working in close proximity to the equipment, and can sometimes cause irreparable damage to expensive turbomachinery.

By taking advantage of Valins program, customers can be confident that their inventory management function is fully optimized.  They can rest assured that the right parts will be in the right place right when they need them, while keeping the peace of mind that their transactional costs are being lowered and the KPIs are being adequately analyzed.

The process industries have control valves with actuators designed to open, close, and control them. Many people prefer pneumatic actuators given their long history, reliability, and high performance.

Application requirements are paramount, but don't overspend when a less expensive option will do.

In this article, featured in Process Heating Magazine, Ryan Kraus discusses the various criteria to consider when selecting a circulation heater.

For the past 30 years, Inventek has utilized the expertise from the engineers at Valin to better understand and master the technology it needs to best serve its customer base.

A simple process method based on the principle that piping pressure losses are approximately proportional to flow squared is presented.

A fuel leak in any part of a generator set can potentially be a catastrophe for the operator. But the issue can be tackled.

While globe control valves are still a viable solution, modern rotary control valves offer many advantages and serve as a more suitable solution in certain process applications.

As long as products have had ethernet ports, people have been asking for remote access to them. They believed they could just plug the devices into the internet, and it would all work. As more software tools became available and internet speeds increased, capable users found ways to give themselves access, however, there was a catch.

The only way to achieve a specified purity level is to select and install proper filtration, with the job intended and the task fully understood. Norman Hall, Filtration Business Unit Manager for Valin Corporation, suggests a correct approach.

Most facilities in the chemical process industries (CPI) require some form of heat. The amount of heat required, and the necessary level of consistency can vary from process to process. Regardless of the details, engineers must decide on a heating source that works best for a particular process.

In terms of what matters to most in the field today, it is safe to assume that reliability, flexibility, accuracy and cost are at the top of the list. With these factors in mind, implementing a silicon-controlled rectifier (SCR) control system for an electric heater is often an optimal approach.

Most people who are familiar with control valves have seen the formula for calculating the valve capacity (Cv) required to pass a given flow rate of water. This seems fairly straightforward until you ask yourself, what is the correct value of differential pressure to use?

Maintaining a consistent internal environment for your enclosures is critical for equipment to function properly. The National Electrical Manufacturers Association (NEMA) has defined standards for specific enclosures designed for the application and environment when correctly installed. Learn more.

Reducing the amount of hydrocarbon leakage from compressor stations is not only imperative for the environment, but for your bottom line. Compressor-related emissions can be reduced by using electric heaters to heat the pressurized natural gas.

Strategic implementation of sensors helps maximize a process from the start and equips operators with enough information to constantly be aware of everything happening in a line. So, what type of sensor(s) will work best for your environment?

Looking for ways to support your systems more easily, more safely, and more quickly for your customers?  Perhaps you are wondering what remote access technology is for industrial control systems.

A lot must be reviewed before selecting the right fitting for power plant instrumentation applications. Among the choices are whether to use single- or double-ferrule designs; heat codes, lubrication, and corrosion resistance must also be considered.

Several different processes require a product to flow through a pipe from one piece of equipment to another. A certain level of heat is often required for this process piping, and this heat must be at very high levels for many applications.

Proper filtration is essential to process flow operation. Improper or lack of filtration can wreak havoc on components, reducing their life and changing the final product. This can lead to equipment failure, process upsets, increased quality issues and in some cases, unplanned shutdown. Learn more.
