Valves are essential components in various industrial applications, including the processing of oil and gas, water treatment, power generation, and chemical manufacturing. They control the flow of liquids, gases, and other materials through pipelines, ensuring that the process runs smoothly and safely. When it comes to purchasing industrial valves, it’s essential to consider several factors to ensure you’re making the right decision. In this blog post, we’ll guide you through the process of buying industrial valves and help you make an informed purchase.

5 Step Suggestions for industrial valve buyers

Step 1: Determine the type of valve you need (An important question for Industrial Valve Buyers)

The first step in buying industrial valves is to determine the type of valve that is appropriate for your application. There are several types of industrial valves, including ball valves, gate valves, globe valves, check valves, and diaphragm valves, among others. Each type of valve is designed to perform specific functions, and choosing the right type will depend on the characteristics of the fluid or material you’re handling, the temperature and pressure of the system, and the level of control you need.

Step 2: Consider the size and pressure ratings

Another important factor to consider when buying industrial valves is the size and pressure rating. Valves come in different sizes and pressure ratings, and you must choose the appropriate size and pressure rating for your system. The size of the valve is determined by the diameter of the pipeline it will be installed on, and the pressure rating will depend on the maximum pressure the valve can withstand without failing. It’s essential to choose a valve with the correct size and pressure rating to ensure it operates safely and effectively.

Step 3: Check for certifications and compliance

When purchasing industrial valves, it’s essential to ensure that they meet relevant certifications and compliance requirements. This will help you avoid purchasing substandard products that may fail prematurely or pose a safety hazard. The most common certifications for industrial valves include API, ISO, and CE. Make sure the valve you choose meets the necessary certifications and standards for your industry and application.

Step 4: Evaluate the manufacturer

The reputation of the manufacturer is another important factor to consider when buying industrial valves. You want to purchase valves from a reputable manufacturer with a history of producing high-quality products. Look for manufacturers with a solid track record of producing valves that are reliable, safe, and durable. You can research the manufacturer’s history and customer feedback to get a better understanding of its reputation.

Step 5: Consider the cost

The cost of industrial valves is another important factor to consider, and it’s essential to find a balance between price and quality. While it may be tempting to opt for the cheapest option, this may not always be the best decision in the long run. High-quality valves can be more expensive, but they are typically more reliable and will last longer, saving you money in the long run.

6 Types of Flow Control Valves & What You Need to Know About Them

Regardless of the industry you’re in, choosing the right type of valves for your application is essential for safety and customer satisfaction.

Installing and maintaining the proper valves may even be legally required.

Valves are an integral part of any pipeline system and a significant investment for businesses. It’s important that your engineers understand how all types of valves work.

How do you know which type of valve is best for your system? Keep reading to learn more about the most common types of flow control valves to help you make an informed decision. 

1. Ball Valves

Ball valves use a spherical plug design that contains a bored-in passage. You can operate these types of valves manually by using a lever, which also indicates whether the valve is open or shut, or automatically, by using an actuator.

This type of valve gives you excellent control of liquid flow through the valve and a secure shutoff when closed. They are often used in sewage treatment, chemical, and paper plants.

2. Check Valves

These types of valves prevent the reversal of fluid flow in piping.

Check valves remain open by the flowing fluid. If the fluid reversed, the valve will close. This type of valve includes lift checks and swing checks. 

3. Butterfly Valves

This type of valve is usually used in the oil and gas processing industries, for oil and gas transmission, in water and sewage plants, and in thermal and hydroelectric power stations.

They are commonly used because they are lightweight, easy to operate, they clean themselves, and there isn’t much pressure drop across the valve when it’s open. 

4. Gate Valves

Gate valves are best used as isolating or stop valves, where you want full flow or no flow.

When they’re fully opened, the fluid will flow in a straight line and there isn’t a significant drop in pressure because of a low resistance to flow. 

5. Globe Valves

Globe valves feature a unique construction designed to make the fluid passing through change direction twice.

They are ideal for throttling and regulating flow with wire drawing and seat erosion. They are cheaper than gate valves but have greater resistance to flow. 

6. Needle Valves

These types of valves offer precise control of flow. They feature a sharp pointed disc and a matching seat.

They are often used for chemical feed control services or continuous blowoff.

It’s worth noting that although needle valves can control flow with precision, they are usually capable of handling only relatively low flow rates. 

Purchasing These Types of Flow Control Valves

As you can see, the best types of flow control valves for your operation depend on your application.

Having a basic understanding of your options will ensure you make the right choice. Being informed will help you make the best decision.
