Sanitary Valve Fittings Installation Guide: Avoid Common Mistakes

In industrial production, sanitary valve fittings are critical equipment, especially in the food, beverage, pharmaceutical and other industries, which have very high requirements for the hygiene of equipment. Correct installation is essential to ensure the normal operation of valve fittings and the long-term stability of the system. Incorrect installation may not only affect the performance of the equipment, but also cause leakage, contamination and system failure. Therefore, understanding the installation precautions of sanitary valve fittings and avoiding common mistakes is crucial to ensure production safety and equipment life. Today, we will discuss some common installation errors and provide you with the correct installation guide.

 

Error 1: Uneven pipe docking

When installing sanitary valve fittings, the flatness of the pipe docking is very important. If the pipe joint is not flat, it may cause the valve fittings to be loosely connected to the pipe and leak. This problem will have a serious impact on production, especially in applications that require high sealing and pollution-free, such as the pharmaceutical and food industries.

 

Avoidance method: Make sure the pipe ends are flat to avoid unevenness or deformation. Use professional tools to check the pipe ports and ensure that all pipe interfaces are properly processed before connection.

 

Error 2: Not using the correct gasket

The selection and installation of gaskets are important links to ensure the normal operation of valve fittings. Using unsuitable gaskets or not installing gaskets correctly may cause leakage or contamination of the medium, affecting the production process and product quality.

 

Avoidance method: Before installation, make sure to select gaskets that meet sanitary standards and ensure that their size and material match the valve fittings. During installation, be sure to check whether the gasket is placed correctly to avoid poor sealing due to installation errors.

 

Error 3: Ignoring the direction of valve installation

Many sanitary valve fittings have clear flow requirements. If the valve is not installed in the specified direction during installation, it may cause the valve to fail to work properly and may even damage the equipment. Especially in fluid control systems, the correct installation direction of the valve is crucial to the flow of the fluid.

 

Avoidance method: Before installation, carefully check the flow direction indication marked on the valve. Many sanitary valves will have arrows indicating the direction of fluid flow to ensure that they are installed in the correct direction.

 

Error 4: No cleaning before installation

In the pipeline system, dirt, oil, dust and other debris can easily enter the equipment. If the pipes and valves are not thoroughly cleaned before installation, debris may affect the flow of fluids and even cause damage or contamination of the valves.

 

Avoidance method: Before installation, be sure to clean all pipes and valve fittings. Use clean tools and disinfectants for thorough cleaning to prevent any contaminants from entering the system and ensure the hygiene of the equipment and pipes.

 

Error 5: Ignoring the tightness of threaded connections

For sanitary valve fittings with threaded connections, the tightness is critical. Improper tightening may cause loose connections, leading to leakage, media contamination or equipment damage. Overtightened threaded connections may damage the sealing gasket or the valve itself.

 

Avoidance method: During installation, follow the tightening torque requirements specified in the valve manufacturer's instructions. Avoid overtightened or over-loose threaded connections to ensure the sealing and reliability of the threaded connections.

 

Error 6: Failure to check the working status after installation

After installation, many people may ignore the testing and inspection of valve fittings, thinking that they can be put into use directly after installation. However, the sealing, operability and fluid control performance of valve fittings need to be tested in detail to ensure their normal operation.

 

How to avoid: After installation, be sure to conduct strict inspection and testing. Check whether the pipeline has leaks, whether the valve can be opened and closed smoothly, and ensure the normal operation of the system.
