Getting to Know Butterfly Valve Types

Industrial equipment and pipelines

Butterfly valves are extremely versatile in industrial settings. They come in a variety of choices, each one unique in its function and application.

Available in rubber, plastic, and metal, these valves are vital for fluid control in many industries. They are used in water plants, chemical units, and places where pressure runs high. This article will help you understand how each butterfly valve model contributes to industrial efficiency. With these insights, you will be better equipped to place orders with your butterfly valve supplier.

Let’s go!

Discovering Butterfly Valve Varieties

In the world of valves, there are three big groups of butterfly valves:

  • Rubber
  • Plastic
  • Metal.

Each kind has its own special traits and uses:

  • Rubber valves are good for applications with medium pressure and mild temperatures. They are also known for their sealing capacity.
  • Plastic valves can stand up to harsh chemicals. They are a go-to in the chemical field.
  • Metal valves are tough. They can handle immense industrial pressure and temperatures.

Knowing these basics, let us look at wafer butterfly valves. They are a smart pick when you are short on space.

Wafer Butterfly Valves- Smart Design for Tight Spaces

Wafer butterfly valves are your best bet in limited industrial spaces. Their smart, slim design makes them easy to install in tricky places.

These valves are also a budget-friendly way to isolate industrial components because they can compactly fit between two flanges.

There are different kinds of offsets in these valves. Each one is designed to work well in certain applications:

  • Zero offset is great for everyday use. It shuts tight in both directions.
  • Single offset makes it easier to turn, making it easier for manual use.
  • Double or Triple offset is for metal seated valves that handle high temperatures.

Picking the right offset is important for smooth running. But if you want something tougher, the Lug Butterfly Valve is a solid pick.

Lug Butterfly Valves- a Strong Mounting for Serious Jobs

As the name suggests, Lug Butterfly Valves have lugs that allow you to mount them right onto the pipe flanges. These lugs have threads to keep the valve steadily mounted on the system.

Lug Butterfly Valves are often the last valve on a line in heavy-duty jobs. They can take the full pressure without extra help. This attribute is crucial in systems where the valve must be strong and safe to avoid leaks or damage.

When choosing a Lug Butterfly Valve, the lug's strength matters a lot. It determines if the valve can withstand the force and high temperature. You also need to check if they are replaceable in case of repairs.

Flanged Butterfly Valves- Strong and Reliable for Big Jobs

Flanged Butterfly Valves are often the best choice for large industrial applications. Their design includes flange faces on both ends, which aid in easy installation. Their tight fit is key for systems that need a solid seal.

Flanged Butterfly Valves are top-notch in big industries because they:

  • Fit tight and strong, which is a must for systems that need a good seal.
  • Shut off tightly, which is good for water treatment and chemical plants.
  • Prevent leaks in high-stakes applications.

While Flanged Butterfly Valves are good for many tough jobs, there are special valves for incredibly high pressures, like Welded Butterfly Valves.

AlterValve sources top-tier industrial valves and parts from global leaders, customized for various sectors like power plants, oil and gas, and petrochemicals across China, India, and Russia. Our steadfast dedication to quality and safety ensures that our products maintain superior standards, delivering dependable performance across industries.

Welded Butterfly Valves- to Withstand High Pressure

Welded butterfly valves are mainly used in systems that require strong connections under high pressure. These valves are designed to withstand tough conditions and ensure the safety and smooth functioning of the system.

Welded Butterfly Valves do not have plastic lining because most plastic ones only go up to certain flange levels. But when the pressure goes beyond what plastic can handle, a Welded Butterfly Valve is what you need.

Knowing the disc alignment in the valve is key to ensuring your valves work well and last various industrial applications.

Understanding Disc Alignment in Butterfly Valves

When dealing with butterfly valves, the alignment of the disc is crucial as it impacts the valve's performance and suitability for different temperatures.

Most plastic-lined valves have zero offsets. This material is ideal for chemical and food industries as it keeps them away from the valve body. Metal valves often have double or triple offsets, allowing the disc to quickly pull away from the seat. This reduces wear and allows them to withstand high temperatures.

A triple offset is the best option for a tight shut and metal seat. It works fast and fits both high and low temperatures.

Wrapping Up Butterfly Valve Insights

Choosing between rubber, plastic, and metal-based butterfly valves depends on your requirements – whether it is handling chemicals or high pressure. However, that’s just the tip of the iceberg. Reach out to your valve supplier to align your requirements with the right valve.

Making a smart valve choice can really boost how well things run and keep them safe. By getting to know the various types of butterfly valves, you can make industrial flow control systems work at their best.
