What Are Industrial Valves?
If you’re looking for a new industrial valve, you’ve come to the right place. Read this article to learn more about Ball valves, Gate valves, and Pressure-tight joints. You’ll also learn how to choose the correct industrial valve for your particular needs.
We’ll also go over what each type of valve does and how to choose the right one for your situation. After you’ve learned about each class, you’ll be well on finding the right one for your next project. You can also learn more through Armstrong Pumps Ontario or other suppliers in your area.
Gate Valves
Since industrial gate valves are used in very harsh conditions, there may be times when you need to repair them. Whether you fix it, the valve is often based on how much it would cost to replace it. Unfortunately, this cost can be 50-65% of the price of a new one. If you are unsure whether you should repair your valve, consider these tips.
Gate valves are typically rectangular or wedge-shaped devices that insert into the flow. They are classified according to their fugitive emissions. The API 624 and ISO 15848-1 fugitive emission standards cover these valves. They are typically made from steel and have a linear stem motion that can cause packing wear or leakage. There are three main types of gate valves: slab, expanding, and wedge. Wedge valves have a wedge-shaped sealing element.
Ball Valves
If you are a business owner or an industrial engineer, you probably already know several different types of industrial ball valves. Each class is designed for specific applications and media. However, there are several things you should keep in mind when choosing these valves.
Below are some of the most important questions when selecting an industrial ball valve. These questions will guide you through the process and help you choose the best valve for your needs.
The port type is the first thing you should consider when choosing a ball valve. There are two main types of ball valves: full port and reduced port. Reduced port ones will reduce flow, while full port ball valves will provide a full-sized flow passage. The latter type is used for pigging and hot-tapping operations. For the last type, you’ll need to purchase a valve with a more critical port than average.
Plug Valves
Large industrial processes require using industrial plug valves, designed with a double-port groove seal ring to eliminate the need for metal-to-metal contact. The seal’s strong friction between the plug and the valve body provides an automatic cleaning effect.
Larger plug valves typically have geared handwheels for manual actuation, reducing operating torques. When using a plug valve, the handle is rotated a quarter-turn to change the plug position perpendicular to the flow. The reverse movement of the handle changes the valve state back to open.
Industrial plug valves are ideal for a wide variety of applications. These valves are used in various industries, including oil and gas, chemicals, pharmaceuticals, power generation, food and beverages, and civil applications. The wastewater treatment industries are the two most significant market segments for the manufacturing of industrial plug valves. Water shortages and environmental regulations are driving demand for these valves worldwide.
Pressure-tight Joints
There are two main pressure-tight joints in industrial valves: socket weld and buttweld. Socketweld is the traditional method, which requires chamfered ends and a V-groove. Buttweld is usually only suitable for smaller valves and flanges. Ring Type Joint (RTJ) flanges have a raised face and a groove for a seal. RTJ is commonly used in high-pressure hydraulic systems.
Another type of valve is bubble-tight. This type is distinguished by the absence of a leak, allowing the flow of liquid to pass through. However, some valve designs are not bubble-tight. These include on-off valves that regulate flow. Regardless of the type, pressure-tight valves must meet all the requirements and specifications of the specific application they’re used in.
