Recently an article was published that presented an easily constructed Excel sheet that estimates hydrodynamic noise in control valves1. A number of people have asked me if there is something similar for aerodynamic noise.
Investing in oil reclamation technology can help reduce the costs associated with oil usage. Learn more in the article below.
A veteran of valve sizing with more than 40 years of experience provides his perspective on how to calculate the compressibility factor of a real gas for control valve sizing purposes.
Most control valve manufacturers include IEC 60534-8-4:2015 in their control valve sizing and selection software to predict control valve hydrodynamic noise. However, users who want to make quick noise predictions or who want to construct valve sizing applications, programming the above noise standard can be a daunting task.
There seems to be this constant game of tug-of-war between Information Technology (IT) and Operation Technology (OT) personnel in industrial settings. In general, there are three misconceptions that OT personnel have about the IT department.
If one wants to be able to do accurate hand calculations, or construct a simple program or Excel sheet, the method described here gives answers that agree exactly with iterative calculations using the equations in the current version of the ISA and IEC standards.
The availability of an easily constructed Excel worksheet that calculates and graphs control valve installed gain in conjunction with the user’s preferred control valve sizing application has prompted a new interest in the application of these calculations. Three examples are shown here.
This white paper discusses the rising stem valve and compares it to the rotary valve. The reader will learn what to consider to ensure the lowest overall life cycle cost and best possible degree of process control.
Kyntronics SMART Hydraulic Actuators combine the best features of hydraulic power with the precision of servo control (used in ball screw & roller screw electro-mechanical actuators), without the inherent disadvantages of those approaches.
Industrial settings with strenuous applications, such as thermal cycling and vibration, are recognized as some of the toughest environments for tube fittings. In all cases, such applications demand highly precise, leak-free technology to ensure protection from vibration and thermal cycling.
A lesson for me is that I need to involve you earlier in the program.
You were tireless in your support and it will not be forgotten!
