Comparative Analysis of Sanitary Butterfly Valves and Check Valves

In industrial production and daily life, various valve equipment is widely used in fluid control systems. Today we will talk about two common valves: sanitary butterfly valves and check valves, and see what the differences are and where their respective advantages are. This article also explains how to choose the right valve if you are looking for a professional sanitary valve manufacturer.

 

What is a sanitary butterfly valve?

A sanitary butterfly valve is a fluid control device widely used in food, beverage, pharmaceutical and other industries. Its core structure is a disc-shaped butterfly plate, which adjusts and cuts off the fluid by rotating the butterfly plate. Because the parts in contact with the medium are mostly made of high-quality materials such as stainless steel and polished, the name "sanitary" is very appropriate.

 

Main features of sanitary butterfly valves:

Easy operation: Just rotate 90° to achieve full opening or full closing, which is convenient and fast.

Clean and hygienic: The surface is smooth and not easy to hide dirt, which is very suitable for industries with high hygiene requirements.

Light weight and small size: Compared with other valves, sanitary butterfly valves are more compact in design and save installation space.

 

What is a check valve?

A check valve, also known as a one-way valve, is a valve that only allows fluid to flow in one direction. It is designed to prevent the backflow of the medium and protect the equipment and pipeline system. The structure of the check valve is varied, and the common ones are lift type, swing type and butterfly type check valves.

 

Main features of the check valve:

Anti-backflow function: effectively protect the pump and system to avoid damage caused by backflow.

Automatic operation: no manual operation is required, and automatic switching can be achieved by relying on fluid pressure.

Diverse structures: different types of check valves can be selected according to needs to adapt to different working conditions.

 

Understand The Main Differences Between Sanitary Butterfly Valves And Check Valves

Functional use:

Sanitary butterfly valves are mainly used to regulate and cut off fluids, and are suitable for occasions that require high-frequency operation and high hygiene requirements.

Check valves are designed to prevent fluid backflow, and are usually used to protect equipment and maintain system safety.

 

Design structure:

Sanitary butterfly valves are mainly based on simple butterfly plate structures and are flexible to operate.

The structure of the check valve is more complex, and may include springs, pistons and other components depending on the type.

 

Applicable fields:

Sanitary butterfly valves are mostly used in food, pharmaceutical, cosmetics and other industries, which require strict hygiene standards.

Check valves are suitable for a wider range of fields such as industry, building water supply and drainage, petrochemicals, etc.

How to choose a suitable valve?

When choosing a valve, you first need to clarify the purpose. If your demand is fluid regulation and high hygiene standards are required, then a sanitary butterfly valve is the best choice; if you are concerned about preventing backflow and protecting the system safety, then a check valve is more suitable.

 

In addition, it is also very important to find a reliable sanitary valve manufacturer. They can not only provide high-quality products, but also recommend suitable solutions according to your actual needs. No matter which one you choose, professional sanitary valve manufacturers can provide you with strong support to make your fluid system more efficient and safer!
