Sanitary three-piece ball valve has the following advantages:
1. Good hygienic performance
Smooth surface: The ball, valve seat and valve body of the ball valve are usually processed and polished with high precision, with low surface roughness, generally up to Ra≤0.8μm or even lower, which can effectively prevent material adhesion and bacterial growth, and meet the strict requirements of food, pharmaceutical and other industries for hygiene.
No dead angle design: The three-piece structure makes the internal flow channel of the valve simple, without dead angles where materials accumulate. When cleaning, whether it is CIP (cleaning in place) or SIP (online sterilization), it can ensure thorough cleaning and avoid residual materials from affecting product quality.
2. Excellent sealing performance
Reliable sealing: The use of advanced sealing technology and high-quality sealing materials, such as polytetrafluoroethylene (PTFE), ethylene propylene diene monomer (EPDM), etc., can ensure that the valve has good sealing under different working conditions, effectively prevent medium leakage, and ensure the safety and stability of the production process.
Bidirectional sealing: Sanitary three-piece ball valves usually have a bidirectional sealing function, which can achieve reliable sealing regardless of the direction in which the medium flows, which increases the installation flexibility of the valve in the pipeline system and also improves the overall sealing of the system.
3. Excellent flow control
Full-diameter design: When the valve is opened, the diameter of the ball is consistent with the diameter of the pipeline, and the medium can pass through unimpeded. The flow coefficient is large, which can meet the requirements of large flow delivery, and the pressure loss is small under large flow, which is conducive to maintaining the pressure stability of the system.
4. Improve production efficiency
Precise adjustment: By rotating the ball, the opening of the valve can be accurately controlled, thereby achieving precise adjustment of the flow rate and meeting the requirements of different production processes for flow control. For example, in the preparation process of food and beverages, the flow ratio of various raw materials can be accurately controlled.
5. Convenient operation
Rapid switching: The operation of the ball valve is achieved by rotating the ball, and the rotation angle is usually 90°. The operating torque is small and the switching speed is fast. The valve can be opened and closed quickly, which is convenient for rapid switching and control in the production process.
Multiple drive modes: It can be equipped with manual, pneumatic, electric and other drive devices to meet different operation requirements and automation requirements. Manual drive is suitable for small systems or manual operation occasions; pneumatic and electric drives can realize remote control and automatic operation, improve production efficiency and control accuracy.
6. Easy maintenance
Simple structure: The three-piece structure design makes the internal structure of the valve relatively simple, with a small number of parts, easy to disassemble and assemble during maintenance, reducing maintenance time and cost.
Easy to replace parts: If a part of the valve is damaged, such as seal wear or ball corrosion, due to its structural characteristics, the corresponding parts can be easily replaced without replacing the valve as a whole, reducing maintenance costs and equipment downtime.
7. Excellent material
Strong corrosion resistance: Usually made of high-quality stainless steel, such as 304 stainless steel or 316L stainless steel, it has good corrosion resistance and can resist the corrosion of common acids, alkalis, salts and other media in the food, pharmaceutical and other industries, ensuring the service life and performance stability of the valve.
High strength: Stainless steel has high strength and hardness, can withstand a certain amount of pressure and impact, is not easy to deform during long-term use, and ensures the normal operation of the valve.
