High Flow Cartridges

For many years, the industry has been guided to a liquid filter cartridge with an outside diameter (OD) measuring 2.5” or so with an inside diameter (ID) measuring 1”, and a length that varied from 5” to 40”. Of course, there are always a few exceptions to the length, but in general, these specifications were very much the standard.

Many engineers may wonder if it is possible to have flashing liquid flow in a control valve even if flow is not choked. The short answer is yes, but it is not very common. This article provides a more detailed answer to this question.

I was recently asked how the installed flow characteristic of an equal percentage valve in a system that includes a significant amount of pipe or other pressure-consuming elements “magically” becomes a linear, or approximately linear, installed flow characteristic.

The ABCs of VFDs

Inside of plants today, AC motors are becoming the industry standard. Many plants are shifting to AC motors from hydraulic motors and in some cases DC motors when powering heavy loads, which were more popular in the past. This shift can be attributed to a variety of reasons and most have to do with cost.

Pipe and Valve Selection

When selecting the pipes and valves to be included in a cooling system, it is important to understand the options available — and the possible outcomes associated with each selection. The selection process is often overlooked or is not given proper attention by designers and contractors. Many factors can impact the effectiveness, longevity and quality of the overall cooling system.

Workplace Safety Still Needs a Human Component

Workplace safety is—or should be—a primary focus of every organization, regardless of whether we’re talking about a classroom, an office, a manufacturing facility, or an oil rig. Employees deserve a workspace that is as safe and secure as it can possibly be.

Cavitation is the 2nd leading cause of a pump system failure. It’s for this reason that a full understanding of what cavitation is, how it is caused and how it can be prevented is critical in the fluid power industry.

In order to get good control with stability throughout the full range of required flow rates, one must use a control valve that has an installed flow characteristic that is linear, or at least as close to linear as possible in most systems.

Considering the number of variables present, gaining precise control of a process heating application can be a difficult task. In industries with a low tolerance for irregularities and a high demand for consistent quality, controlling the temperature of a substance from the start to the finish of a process is an absolute necessity.

Loss of containment is one of the costliest things that can go wrong at a plant. Accordingly, smart enterprises employ a variety of measures that ensure loss of containment just doesn’t happen – or when it does, the adverse circumstances are kept to a minimum.

Just as sound can have negative effects on the human body, certain frequencies can play havoc on industrial equipment. When control valves are not selected appropriately, there is an increased risk for cavitation, which causes high noise and vibration levels, resulting in very rapid damage to the valve's internals and/or the downstream piping.

Advanced Process Control (APC) methods used to be so advanced as to be esoteric- too complex and unusable except by a few high-level experts. Today, however, it seems APC is little talked about for an entirely different reason: It’s become a commodity.

Rule of Thumb for Control Valve Sizing

When control valve professionals talk about "control valve sizing," they really mean the entire process of selecting the valve that will do the best job of controlling the process. Selecting the right size valve is an important part of the process, but there are other equally important considerations as well.
