Beauty or a Beast? Using NDE on Valve Components

When it comes to valves, “beauty is only skin-deep” is often a true statement. Since Superman and his X-ray eyes don’t really exist, there is no way to verify the quality of a valve or valve component just by looking at it.

Education

Stress Wave Monitoring

Surfaces in relative motion or in contact with each other  — such as bearing or gear components — produce a frequency response when they interact.

The Valve Industry Finds Value in ESG Initiatives

The valve manufacturing industry in North America is one of the industries that have embraced this new way of thinking and is leading the way with the integration of environmental, social, and governance (ESG) initiatives. These initiatives range from valves designed to mitigate climate change to community involvement activities.

Technical

Leak Testing Gas Components and Systems

Leak testing is performed for four basic reasons, says John McLaren, product manager, leak detection at Agilent Technologies, Inc.

Education

Electric Actuators in the Oil and Gas Industry

Actuators in the oil and gas industry operate many types of valves, and they must do so with great precision and accuracy.

Design

The Case for RFID in Process Plants

Today, much of the information regarding the status of components installed in the field is housed in paper files, which poses problems for technicians and engineers.

Technical

The Challenges of Creating Super-Clean

Because biopharmaceuticals are produced using living organisms, and the drugs produced are used in humans and animals, the cost of contamination is very high and sterilization of the process system is critical.

Education

Thermodynamic Processes: Flashing and Cavitation

From time to time, we re-publish well-received or particularly valuable articles that have previously run on VALVEMagazine.com so that those who might have missed them will be able to catch up on the best of the best.

Gaskets Are Not Created Equal

Gaskets are near the bottom of the food chain of valve components; trim, body materials and packing seem to get a lot more press.

Technical

The Critical Stem Nut: Who is Responsible for Maintenance?

One of the most important components of an automated threaded stem valve is the ubiquitous stem nut, a relatively simple and unsophisticated mechanical device that converts the rotary motion of an actuator into the linear stem movement needed to open or close one of the many types of gate valves or sluice gates.

Technical

Hardfacing Alloys and Processes for Advanced Ultra-Supercritical

Cobalt-based Stellite 6 has been the workhorse for providing improved wear resistance and service life in valve components installed in power generating facilities for over 75 years.

Technical

The Underappreciated Mounting Kit

All too often, the mounting kit is considered trivial, an afterthought deemed a commodity within all the other specified control components that comprise a complete automated valve package.

Technical

Enhancing Valve Component Performance Through Design by Nanolamination

Today, the total cost of corrosion in the U.S. exceeds $1 trillion annually—and from oil & gas operations to municipal infrastructure, metal-based components like valves are in some of the most corrosive environments imaginable.

Technical

European vs. U.S. Temperature Code Ratings for Solenoid Valves

Solenoid valves are vital components of many process automation systems.

Technical

New CAD Modeling Tools for Pneumatic Components

Experienced engineers know that not all supplier CAD tools or files are created equal.

Technical

A.W. Chesterton: 1724 Low E Sealing System

Achieving Low E Fugitive Emissions Compliance in Chemical Industry Valve Stem Sealing A.W.

Applications

A Primer on Castings

Valve components, such as bodies, bonnets and caps, are manufactured either by forging or casting.

Design

Understanding and Selecting Valve Flanges, Pt. I: Design and Standards

Because flanges allow the assembly and maintenance of system components without the need for cutting and welding pipe, they play an important role in piping systems.

Applications

Choosing Valves for New No-Lead Water System Regulations

In the U.S., regulations governing lead content of the components of potable water systems have seen considerable changes as safety restrictions tighten.

Applications

Tapping into Wastewater Heat

Anyone who plans, builds or operates water distribution systems attachs great importance to efficiency as well as the reliability of system components.

Insights

Success Through Supply Chain Collaboration

With valve components sourced from numerous suppliers around the globe, valve, actuator and control manufacturers are faced with a significant number of challenges while attempting to meet the desired flow control at a competitive price.
