Sanitary pneumatic butterfly valves are widely used in industries with high hygiene requirements such as food, beverages, pharmaceuticals, and cosmetics. They have the following main advantages:
1. Excellent hygienic performance
Excellent material: The valve body and butterfly plate are usually made of high-quality stainless steel, such as 316L stainless steel, which has good corrosion resistance and can resist the erosion of various chemical media, avoid impurities caused by corrosion, and ensure the sanitation and safety of the system.
Fine surface treatment: The inner surface of the valve is polished with high precision, with low surface roughness, and it is not easy to adhere to materials, which reduces the possibility of bacterial growth, and is easy to clean and disinfect, and can meet strict hygiene standards.
No dead angle design: The structural design is simple, and there are no dead angles or gaps where materials are easily accumulated, making cleaning more thorough and effectively preventing product residues and contamination.
2. Good sealing performance
Use high-quality sealing materials: Generally, sealing materials such as rubber or polytetrafluoroethylene (PTFE) that meet FDA standards are selected, which have good elasticity and corrosion resistance. These materials can fit tightly with the butterfly plate when the valve is closed, forming a reliable seal, effectively preventing medium leakage and ensuring the sealing of the system.
Reliable sealing structure: The unique sealing structure design can adapt to different working pressure and temperature conditions, and maintain stable sealing performance during long-term use. Even in the case of frequent opening and closing, the integrity and sealing of the sealing surface can be guaranteed.
3. Small fluid resistance
Large diameter when the butterfly plate is opened: When the sanitary pneumatic butterfly valve is opened, the butterfly plate is fully opened, and the diameter of the valve is almost the same as the inner diameter of the pipeline. The medium can flow smoothly in the pipeline with minimal fluid resistance. This helps to reduce the energy consumption of the system and improve the fluid delivery efficiency, especially for media with high viscosity or containing particles.
Streamlined design: The internal flow channel of the valve is designed to be streamlined, which reduces the turbulence and eddy flow of the medium in the valve, further reduces the fluid resistance, and makes the flow of the medium more stable.
4. Convenient operation
Pneumatic drive: It adopts pneumatic actuators and uses compressed air as the power source, which has the characteristics of fast response speed and large operating force. It can realize fast opening and closing actions to meet the rapid control requirements in the automated production process.
Remote control: It can be integrated with the automated control system to realize remote control and monitoring. Operators can switch the valve and monitor the status through computers or controllers in the control room, which improves the automation and management efficiency of the production process.
Simple maintenance: The structure is relatively simple, with fewer parts, which is easy to install, disassemble and maintain. The maintenance cost of the pneumatic actuator is low. It only needs to regularly check the operating status of the air source system and the actuator, and replace the worn seals and wearing parts.
5. Long service life
High-quality materials and manufacturing processes: The key components of the sanitary pneumatic butterfly valve are made of high-quality materials, and undergo strict processing technology and quality inspection to ensure the overall strength and durability of the valve. It can withstand long-term working pressure and medium erosion, and is not prone to wear, deformation and other problems, thereby extending the service life of the valve.
6. Good adaptability
It can adapt to different working environments and medium conditions, such as high temperature, low temperature, corrosive medium, etc. By rationally selecting materials and sealing structures, it can meet the use requirements under various complex working conditions and reduce the possibility of valve damage due to changes in working conditions.
