Recommended Practices (RP) Changing Engineering and Supplying of Assemblies

The issue is that assemblies are not currently treated as “engineered” items; they are often produced by slapping the actuator on the old (or new) valve specified by the piping requirements without much understanding of the specifics of the interactions between valve and actuator connections through the drive train (coupling).

Automating Old Sluice Gates with Electric Actuators

Since the early days of water and wastewater treatment plants in the United States, municipalities and industries have continued to expand and upgrade existing plants and distribution infrastructure as well as build new facilities.

2020 Can Be a Year of Education and Networking

The new year presents several exciting opportunities for those who manufacture and work with valves, actuators and related products.

Technical

Linear Actuators for Automating Gate Valves

Most professionals in the valve industry are already familiar with the use of linear actuators to operate globe valves.

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.

Back to Basics: New Valve Modifications

Valve modification can be defined as: adding value to standard or “commodity” valves by installing actuators, special trims, different end-connections, packing and gaskets, and other accessories or upgrades not provided on the original product.

Technical

Electric Actuator Commissioning

Typically, electric actuator commissioning is performed when the actuator is installed at site.

Gearboxes 101

Gears have a long history and have been used for many purposes throughout civilization.

Shaping the Valve Industry’s Future

The British Valve & Actuator Association (BVAA) is coming to the end of the second year of its innovative Future Leaders Program. “It is quite possibly the most rewarding activity of my career.” said BVAA’s Director & CEO, Rob Bartlett. “The program has had an amazing effect on all those involved in it.

Technical

Valve Stem Material Selection for Offshore Actuated Valves

This article aims to resolve the problems that can occur when high actuator torque has a negative effect on the stem of the valve in offshore service.

Technical

AIV, LP Acquires Zenith Supply

AIV, LP, a Houston-based global wholesale distributor of valves and actuators for the oil and gas, power generation, chemical, petrochemical, refining, pulp and paper and water treatment industries, has announced that it has acquired Zenith Supply.

Technical

Adopting the IIoT: Are Results Matching the Hype?

Many valve, actuator and control manufacturers have jumped right in and taken advantage of the opportunities the Industrial Internet of Things (IIoT) have brought to process control.

Technical

Sizing Electric Actuators for Use on Linear Valves

The valve industry is made up of many types of valves that are used in countless types of applications, locations and service conditions.

Technical

The Actuation Selection Process

A common misconception in our industry is that actuating a valve is as simple as putting the most cost-efficient actuator on top of your valve of choice, but the process is much more complicated than that.

Technical

Force and Direction Controls for Valve Actuators

Valve actuators deliver either linear or rotary force.

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.

Controlling Our Water Systems, Part II

To better understand the actuators and controls in our water systems, we discussed the types and some of the considerations for sizing in the first part of this article, which appeared in the print version of VALVEMagazine and is posted here.

Applications

Controlling Our Water Systems

Actuators and controls are a critical process of how we move water through our supply and waste systems.

Technical

Variable Frequency Drives in Electric Actuators

Electric actuators are vital for operating a wide variety of valves and are used in many industrial applications.

Valuable Insight from Valve Actuator Users

Once valves and actuators are installed and commissioned on site, the manufacturer’s involvement often lapses to an occasional service call.

Is Your Company Ready for The New Reality?

Since August, 2015, when VMA’s 2016 Market Outlook event was held, there have been a few more bumps in the economic road for valve, actuator and control manufacturers, their suppliers, distributors and end users.

Technical

A Beginner’s Guide to the Right Actuator (Consider the Valve!)

A valve, in its most basic form, consists of a body and an internal moving component (closure element), which shuts off or restricts flow through the valve.

Technical

Electric Vs. Fluid Power Choice for Valve Actuators

Since the early days of valve actuator use, there has been a choice between powering the actuator with electricity or pressurized fluid.
