Control Valve Selection for Chemical Service
Dale Stepanek, DFT, Inc.
Use the “size/cost” method when facing technical overload.


SPRING


Advanced Packing Technology Minimizes Maintenance, Improves Performance of Knife Gate Valves
Al Libke, DeZURIK/SPX Valves and Controls
The brute-force ruggedness and affordability of the knife gate design, combined with the packing performance of much costlier valves can only mean broader horizons for this workhorse valve.

The Future for Triple Offset Butterfly Valves
John Furness, Curtiss-Wright Flow Control
After years of development and testing, the butterfly valve of today is now a precision-engineered product capable of being used effectively in a wide range of applications that were previously only considered suitable for gate, globe or ball valves—and at a fraction of their cost.

Guidelines for Selecting the Proper Valve Characteristic
Michael Headley, Fisher Controls International
Need to decide what valve characteristic to use? This article makes recommendations for the four basic process controlling variables: liquid level, pressure, flow and temperature.

PRODUCT FEATURE: Technological Advances from Suppliers to the  Valve & Actuator Industry
Mark Francis, VMA Staff
Suppliers play a key role in the U.S. and Canadian valve industry. They provide raw material, components and process equipment used by valve and actuator manufacturers.

Made in the USA?

Preventive Maintenance on Automated Valves
Chris Warnett, Rotork Controls
If you would like to take full advantage of the benefits and capabilities of today’s actuators and software, but don’t have the time or expertise to spend on maintaining these complex products, consider having the equipment’s manufacturer handle your maintenance program.

The Enemy Within: Critical Operating Conditions in Control Valves
Ralph Herbrich, Ph.D., SAMSON AG
To avoid problems with the control valve process, the best strategy is to tailor the valve to the specific application. If unexpected problems such as cavitation and flow limitation occur, consider installing special throttling elements in standard valve bodies.

The Control Valve’s Hidden Impact on the Bottom Line (Part 1)
Bill Fitzgerald, Emerson Process Management, and Charles Linden, Omaha Public Power District
