Our Top 5 Industrial Valve Articles of 2016

2016 was quite a year! The manufacturing industry saw a significant rebound, and oil prices started to recover as well. Both of these trends are expected to continue in 2017.

At Allied Valve, we also saw some big changes this year. We expanded our product line to include Masoneilan control valves, CDC rupture discs, and Groth relief valves and flame arresters. We also beefed up our service capabilities with a new Mobile Lab trailer and new control valve testing systems.

Finally, we continued our initiative to bring you valuable content related to valves, actuators, and the many industries we serve. Here are our top 5 industrial valve articles of 2016.

Maximizing Your Control Valve Performance: A Guide to Control Valve Selection, Maintenance, and Repair

Process plants can contain thousands of control valves, responsible for keeping process variables like flow, level, pressure, and temperature within the desired operating range. Despite their importance to product quality, efficiency, and a company’s bottom line, control valves are often neglected. This article provides an in-depth look at the factors that affect control valve performance and how to keep your valves always working their best.

Warning: Hydrostatic Testing of Systems with Valves Containing Thermodiscs May Damage the Valves

It came to our attention earlier this year that some safety valves containing Thermodiscs (e.g., Consolidated 1811 and Consolidated 1711 series) were being put through hydrostatic testing. These valves are designed for steam service only and water can cause damage, potentially beyond repair. This article describes the problems that hydrostatic testing can cause and what you can do to mitigate these problems.

What’s Wrong With Your Actuator? 5 Things to Check

Actuators can go on the fritz for many reasons, but the underlying cause is usually a problem with one of five components:

  • The valve
  • The center column drive
  • The connection to the valve
  • The contactor
  • The motor

This article describes the problems related to all of these components and how to solve them.

ANSI/ISA-75.19.01 Hydrostatic Testing of Control Valves

The American National Standards Institute (ANSI) and the International Society of Automation (ISA) provide standards for the hydrostatic testing of control valves. The goal of the test is to verify the valves’ structural integrity and leak tightness. This article summarizes the fluid, pressure, and time requirements of hydrostatic testing as well as the standards for acceptable performance.

Preventative vs. Predictive Valve Maintenance: What’s Right for You?

To work properly when they’re needed, all valves must be maintained. It used to be that preventative maintenance was the only option. But with the diagnostic tools available today, it’s possible in some cases to use a data-based predictive approach instead. Both of these approaches are part of an effective valve maintenance program. This article helps you understand when each of them is most appropriate.
