Quickly Understand 5 Types Of Sanitary Valves And Their Uses

Sanitary valves are one of the indispensable equipment in industrial production, especially in food processing, pharmaceutical, beverage manufacturing and other industries. Their hygiene standards are directly related to the safety and quality of products.

Do you know about sanitary valves? Next, follow this article to quickly learn about five common sanitary valves: ball valves, butterfly valves, check valves, diaphragm valves and sample valves, including their characteristics, working principles and applicable scenarios.

Ball Valve:

The ball valve uses its internal rotating sphere as the main component, and controls the flow or cutoff of the liquid by rotating the angle of the sphere.

1. Features:

The ball valve has a simple structure, smooth internal flow channel, is not easy to accumulate impurities, has excellent sealing, and is flexible to operate. It can be switched by rotating 90°.

2. Working principle:

There is a through hole in the ball. When the hole is aligned with the pipe, the liquid can flow freely; when the hole is rotated to the vertical direction, the fluid is completely blocked.

3. Main uses:

Ball valves are often used in scenarios that require frequent opening and closing, such as dairy processing and brewery production lines, especially suitable for high viscosity or particle-containing liquids.

Butterfly Valve: 

The core of the butterfly valve is a disc-shaped valve plate, which adjusts the flow of liquid by rotating the valve stem.

1. Features:

Simple structure, small size, light weight, easy operation, fast switching speed. Butterfly valves can be used to cut off fluids and adjust flow.

2. Working principle:

The valve stem drives the valve plate to rotate. When the valve plate is parallel to the pipeline, the liquid flows unimpeded; when the valve plate rotates to a vertical position, the liquid is blocked.

3. Main uses:

Suitable for low-pressure or medium-pressure systems, widely used in beverage processing, food delivery, and cosmetics production.

Check Valve: 

Check valve, also known as one-way valve, is an automatically operated valve that only allows fluid to flow in one direction to prevent backflow from affecting equipment or production.

1. Features:

High degree of automation, no manual operation required, automatically opened or closed by fluid pressure.

2. Working principle:

When the liquid flows in the set direction, the valve core is pushed open; once the liquid tries to flow back, the valve core will automatically close to prevent backflow.

3. Main use:

In the food and pharmaceutical industries, check valves are mostly used to prevent liquid backflow from contaminating the production line, such as in the delivery pipeline of dairy products.

Diaphragm Valve: 

The diaphragm valve is one of the valves with higher sanitary levels. Its internal structure uses an elastic diaphragm to completely isolate the fluid from other components.

1. Features:

Designed for applications with high hygienic requirements, it can avoid cross contamination and fluid leakage and is easy to clean.

2. Working principle:

The diaphragm is pushed to press the valve seat through a handwheel or pneumatic device to cut off the fluid; after loosening, the fluid can pass freely.

3. Main use:

It is particularly common in pharmaceutical, food and pure water treatment systems, and is used to transport high-purity or highly corrosive media.

Sample Valve: 

The sample valve is a small valve specially used to collect liquid samples from the production line. Although it is small in size, it undertakes the important task of ensuring product quality.

1. Features:

Compact design, simple operation, and the ability to obtain samples without interrupting production to avoid waste.

2. Working principle:

The valve is opened manually or pneumatically to lead a small part of the fluid out of the pipeline for testing, and the valve is closed immediately after sampling.

3. Main uses:

In the dairy, beverage, and pharmaceutical industries, sample valves are used for real-time quality testing to ensure that products meet standards.

In summary, sanitary valves play a very important role in industrial production. Through the introduction of the above five sanitary valves, I believe you have a better understanding of sanitary valves so that you can better choose the right valve according to your specific needs. This can not only improve production efficiency at work, but also ensure product quality and process safety.
