Howard Williams, Rotork Controls

Gas and oil pipelines are essential to America's success. By using today's valve actuator technology along with other proactive security and safety methods, major catastrophes can he avoided or at least mitigated.

Valve Trim Retrofits: Solving Chronic Control Problems
Robert E. Katz

Trim retrofit proves itself to be a viable, relatively inexpensive, and successful way to eliminate chronic noise, vibration, trim damage and operational instability problems in control valves throughout industry.

Can You Afford Not To Develop a Proactive Relationship with your Suppliers?
Clay D. Canterbury
If you feel your company cannot afford to expend resources for proactive communication with your supplier base, one question must he asked: can you afford not to?

The Extension Bonnet Cover-Up: Too Often a Mistake
Ron Funk
Do you typically insulate control valve extension bonnets in high-temperature applications? You may not want to, and here are the reasons why!


How Today's Actuators Can Interface Effectively with Control Systems
Howard Williams

Today, applications that require automated valve operation can be easily and cost effectively networked and interfaced to the plant's distributed control system. There are many different options to accomplish an effective link, depending on the application's specific requirements.

Understanding Hydraulic Shock
Charles Stutsman

Hydraulic shock is too often overlooked when valve selections are made. The rapid closing time of quarter-turn valves, swing check valves and actuated valves is as critical a consideration as pressure and temperature limitations if not properly addressed.

Increase Process Accuracy with High Modulation Electric Actuators
Jose Huyke

Utilization of these types of high modulation actuators will thus complete the high performance loop requirements in today's processes; justifying their investment with increased process accuracy and performance.

Thermal Spray Technology
John Williams & Dr. George Kim

Thermal spray coatings are widely used in applications that require wear protection, corrosion protection, a thermal barrier, dimension control, and component restoration, to name a few examples.

Control Valve Stem Seal Options
Andrew D. Butcher, Spirax Sarco

In order for stem seals to be effective, it is essential that the correct type and material of seal be selected to suit the conditions of service.


Deepwater Sub-sea Ball Valves
David R. Medford

With the growing development of deep water oil and gas fields and the increasing need for larger bore, higher pressure valves, a move to consider ball valves as another option to traditional gate valve solutions has been growing in popularity.

Internet Security: Safeguarding Your IT Investment
Will Garvin
This article covers some of the security tools available for network and internet security, and offers items for consideration in developing an IT security plan.

Control Valve Positioner Technology
Andrew D. Butcher

Reducing the Cost of Addressing the PED
Lindsay Bredemeyer
There are exclusions and application limits within the PED which significantly reduce the cost and effort of addressing the PED by avoiding the more expensive aspects of PED compliance.

Getting Closure on Compliance: Putting Valve Related Safety Standards in Perspective
Joseph Wright
Existing safety standards give us access to an evolving body of information needed to build, maintain, and operate processing plants safely.


Advances in Valve & Actuator Technologies
With increasing foreign competition, U.S. and Canadian valve and actuator manufacturers face the continuing challenge of developing and producing innovative products to address the needs of the flow control industry.

Superior Actuator Diaphragm Material for Control Valves in Low Temperature Applications
Ted Grabau, Emerson Process Management

A newly developed actuator diaphragm material for use in control valve applications provides extended service temperature capability, particularly at sub-zero temperatures.

World Standards for Safety Valves
Stephen Gow, Spirax Sarco

Confusion can occur when comparing different standards because in some cases, the same term has a slightly different definition, or the same definition is referred to by different terminology.
