The 4 Factors to Determine Which Valve Type You Need

24 May 2019

The selection process for industrial valves is not overly complicated. However, if you’re not careful, you will end up selecting an incorrect valve. You can avoid this if you’re keen enough when it comes to choosing the right one.

However, the question is, how? How do we know if it’s the correct valve? Where should we start searching?

There are a lot of factors involved when it comes to choosing the appropriate valve for your industrial needs. Though sizing and selection can be a tedious process, understanding the requirement for applications will make it less complex.

To help you with the selection process, below are valuable details for you to take note.

The Type of Valve:

One of the most important things you need to consider is the valve type. The type of valve needed will basically depend on the function, operation, and flow control. If flow control is needed in the process, then you will need a valve with good control performance. The size and type of a valve should be selected to support control of flow.

Those valves with plugs can be picked to change the flow of the valve. When it comes to the shutoff application, butterfly or gate valve is mostly recommended. This type offers good throttling capabilities. On the other hand, plug and ball valves are not the best options to control flow.

Moreover, if the process needs backflow prevention, then it is best to opt for a check valve. A mixing valve is an ideal choice for blending two streams process as well as water stream tempering. If the process involves feeding chemicals which are known to be a compounding process, what you need is a valve that provides the needed control capabilities.

Performance Specifications and Valve Measurement:

This is the most crucial step in choosing the appropriate valve for the application. In the event you chose an incorrect valve, it can cause issues to the valve operation within the fluid transfer system. For example, a valve that is undersized can smother the downstream flow, thus creating an upstream pressure. Valves that are oversized can only regulate a limited range of flow.

Valve operation in a nearly closed position may lead to flushing and cavitation. In the event of severe oversizing, you can pull the valve plug. This will shut off the flow. If the application needs an isolating valve, then the valve can be measured to the existing hose or pipe. Flow sizing can be a lot complicated because of the changes in flow constriction as well as the gap between the seat and the plug.

Construction of Valve Materials:

Another important factor for your valve selection process is the body materials. The environment that surrounds it, the flowing media, and maintenance are great factors that will create an impact on the valve materials. Media that are corrosive, such as saltwater, acids, chemicals, or certain food types may lead to corrosion resistant of valve materials.

If the media is a mixture of liquid with abrasive solids, then the materials’ resistant to erosion of construction are needed. It is also required to have a high strength alloy for high-pressure media to endure internal pressures. A valve with hot media will highly need an alloy that maintains durability and corrosion or oxidation resistance during an increase in temperatures.

Valve Connection and Actuation:

Put into consideration how your valve will be operated within the production. This is one important aspect should not take for granted. For manual valve operation, you need the one that has a hand wheel for manual valve opening and closing. As for an automatic valve, the one installed in a vehicle or aircraft will need an electric actuator to slide the stem. This is done through signal inputs control.

The operation of check valves is operated within the system through a pressure drop. This does not usually need any actuation process. Another selection factor to consider is the fitting type of a valve, which is often defined by the actual connections in the piping system. The connections of a valve are not considered as the fundamental criteria for selection.

Suppliers usually provide the same valve with various options for connections. Also, an adapter fitting can be purchased in the event the requested type of connection is not feasible. There are certain industries that have specific standards, regulations, and codes that are required to be followed.

Other cases, a valve must follow to these standards — NACE, API, etc. — prior using it in pressure vessel, refinery, nuclear, or other crucial applications.

Conclusion:

When selecting the right valve for your production, make sure you are packed with all the necessary details. Get to know some basic information and learn to compare each option to determine which is which. Regardless of what valve type your production needs, it is highly recommended to order from a reputable and trusted industrial valve supplier. Surely, it can get a bit complicated sometimes, but once you already have knowledge regarding what factors to consider, the selection process isn’t that hard after all.

Why Sensors are Essential in Machine Automation

In machine design, the role of a sensor is paramount in converting any physical property into an analogue signal which facilitates automation. Machine automation is responsible for the industrial revolution that bolstered economies around the world. Different physical properties require the interpretation of a sensor such as distance, position, temperature, and liquid flow. This article aims to describe each sub-category of sensors according to the property converted. Reason For Using The Machine Automation Sensors There are different reasons for using the machine automation sensors that you need to take care off while you want to improve your learning process. Position sensing: Detecting the position of an object is possible using different types of sensors specifically measuring linear or angular motion. Encoders, potentiometers, and linear transducers are some of the preferred methods of sensing linear displacement. These devices are compatible with different types of machine assembly. Linear sensors used in rugged industrial applications commonly use a non-contact inductive technology to reduce the effect of friction and wear and tear. Distance sensing: Distance sensors can measure the rough distance and often function as a “within range” detecting device. Some distance sensors are programmable such that you can identify the distance of a target object even at an approximate location. Photoelectric sensors which use light in sensing distance can also work as a distance transmitter. A photoelectric transmitter can detect a distance range of between less than 5 mm to more than 10 m. The resolution is better at short range, but even if the resolution quality decreases at a more extended measurement range, it is still good enough for most machine automation applications. Speed sensing: Hall-effect, photoelectric, and inductive sensors are commonly used to sense speed and location. The preferred output is usually a train of digital pulses. A speed switch is typically used for machine automation in monitoring the speed of rotating shafts and identifying whether it is turning too fast or too slow; hence creating problems with the process. As a control mechanism, a sensor signals when the machine is running too fast so that it can automatically shut off. Fluid flow sensing: A fluid flow indicator is a sensor used explicitly in measuring the flow rate of liquid or gas. A typical flow sensor consists of a paddle wheel or a float. Some practical applications of a fluid flow sensor include water monitoring in wastewater processing plants and flow indication in HVAC systems. In most applications using a flow sensor, the sensor can provide either a digital or analogue output. Although there are several ways to measure liquid flow, one that works to detect differential pressure produces the most precise measurements and fastest response time. Temperature sensing: Sensors used in monitoring temperature come in a wide range of configurations suited for different applications. Sensing changes in temperature in machine automation is essential. It helps determine when a machine overheats, and to maintain the optimal setting for the device to work correctly. Examples of uses for temperature sensors include boilers, large motors, and compressors. Aside from the temperature sensor, switches are also included in the configuration to aid with temperature control and monitoring.

Waterjet Vs. Laser Cutting: Which Is Worth The Hype?

Waterjet and laser cutters can slice through materials that no other cutting tool can. They are invaluable for prototyping products and precision manufacturing. But which one is worth the hype - waterjets or laser cutters? This article provides everything you need to know about waterjet vs laser cutting units. Learn how they work and which one is best for your industrial manufacturing facility. Waterjet Vs Laser Cutting: Unlike the vast majority of blades and saws, waterjets and laser cutters don't have a blade. The lack of a blade makes engraving and detail work much more precise. And, waterjets and laser cutters are computer operated, as to achieve a very high level of precision. Both machines can engrave minute lettering and symbology into a wide range of manufacturing materials. But each machine goes about it a very different way. Both methods of cutting excel with 2D objects and engraving, but which is better: waterjet or laser cutting? What Is Laser Cutting? Laser cutting uses a high-focus laser to cut or engrave materials. Laser cutting is a method of subtractive manufacturing, which means it only takes away material. This is in opposition to additive manufacturing, like 3D printing. Special software guides the lasers using mirrors. A gas power source provides energy to the system, usually in the form of CO2. The CO2 fuels the laser which outputs between 1,500 and 2,600 watts. Some systems implement an additional gas jet to expel the excess material. Laser cutting is a very precise form of subtractive manufacturing. The intense heat of the laser cuts through material like a razor using a precision burn. Laser systems cut material from sheets or large panels. Laser Cutter Materials: Laser cutting systems make precision cuts in a wide range of materials. The only material that a laser cutter is not "cut-out" for is reflective metals. The reflective property of some metal reflects the laser off of the cutting surface, which can be dangerous. Laser cutters are great for cutting glass, wood, plastic, and a wide range of metals. Laser cutters encounter obstacles, however, when trying to cut compound materials. If the material contains multiple materials, then it has multiple melting points. If the material has multiple melting points, then a laser takes longer to cut through it, and cuts can become uneven. Laser cutting systems work the best with flat sheets of material, with a thickness range between 0.1 inches to just under a half-inch. And, most laser cutting systems proficiently perform the functions of cutting, drilling, engraving, welding, ablating, and structuring. What Is Waterjet Cutting? Waterjet cutting systems utilize a high-pressure waterjet to slice through materials. The water is shot through a very fine point and creates over 60,000 pounds of pressure per square inch. For tougher materials, a mixture of water and an abrasive acts like a diamond saw blade. Garnet is a common abrasive for use in waterjet cutters. Aluminum oxide is another common abrasive that you can use with a waterjet cutter. The process of waterjet cutting is a high-speed version of natural erosion. With a big enough waterjet cutter, you can make another grand canyon in a fraction of the time. Read more about how the best water jets can cut through anything nature makes. Waterjet cutters differ from laser cutters in that the power source does not reside with the cutting unit. Since a waterjet cutter outputs between 4 to 7 kilowatts, the water pump is located away from the worksite. This is also true because the water source is rarely nearby your bench. Waterjet Cutting Materials: Unlike a laser cutter, waterjet cutters can effectively cut almost any material. They have no problem cutting through compound materials with multiple material types. The pure pressure of the water jet is enough to cut cleanly through anything. Waterjet cutter units are especially useful for cutting precisely through masonry. They're also good for cutting and structuring stone, thick metals, ceramics, and glass. Waterjets handle thicker material than laser cutters. They can handle material that is up to around 2 inches thick. But they don't do as well with material thinner than 0.4 inches. Level of Waste from Waterjet vs Laser Cutting: Laser cutters create a minimal amount of off-fall and waste. Very little, if any, cleanup is required after cutting. The only waste that laser cutting produces is a small amount of dust that is easily vacuumed up. Waterjet cutting, on the other hand, creates a lot of waste. You might think that waterjet cutting would be cleaner, but it is not. The abrasive material in the water adds a toxic element to the off-fall liquid. For this reason, waterjet cutting requires special waste-water disposal, safety gear, and a bigger project budget. What's the Cost to Purchase and Operate a Waterjet vs Laser Cutter? A plasma laser cutting machine will cost between $15,000 to over $250,000 at the initial purchase. Waterjet cutters are more expensive because they require more specialized materials. They range from $100,000 to around $400,000. On average, either machine will cost around $350k. Expensive industrial machines can exceed $1,000,000. On average, a laser cutter costs between $13 to $20 an hour to operate. Waterjet cutting systems run between $15 to $30 an hour to operate. Final Thoughts: At the end of the day, waterjet cutters cost up to five times more to operate than laser cutters. Waterjet cutters can cut thicker and more complex materials, but they are slower than laser cutters. So, when considering waterjet vs laser cutting, laser cutting will save you time and money.
