Food and pharmaceutical hygiene grade three piece ball valve

Sanitary grade three piece ball valve is a fluid control device designed specifically for high hygiene standard industries such as food, medicine, and biotechnology. Its core features are compact structure, easy disassembly and cleaning, and reliable sealing. It is suitable for sterile, corrosive, or frequently sterilized working conditions. The opening and closing of the medium and flow regulation are achieved through the 90 ° rotation of the sphere, which combines efficiency and safety, and is a key component in modern production lines.

Structure and Design

The three piece ball valve consists of a left valve body, a right valve body, and a middle valve body, which are connected by bolts (such as ISO-5211 standard design), supporting quick disassembly and maintenance, avoiding the need to disassemble pipelines to inspect internal components, significantly reducing downtime. The valve body material is mostly made of 316L or 304 stainless steel, with a mirror polished surface (Ra ≤ 0.8 μ m) to ensure no residual dead corners and meet hygiene certification requirements such as FDA and EHEDG. The sealing components are made of PTFE and PPL, with a wide temperature resistance range (-10 ℃~120 ℃), compatible with corrosive media and high-temperature steam cleaning.

performance advantage

1. No retention design: Full bore flow channel and seamless welding process, supporting CIP/SIP online cleaning, meeting GMP standards.

2. High sealing performance: The ball and valve seat are precisely ground, and the elastic sealing structure achieves bidirectional zero leakage, which can also operate stably in a vacuum environment.

3. Easy to operate: manual, pneumatic, or electric drive options are available, with a 90 ° rotating handle for quick opening and closing, low torque, and support for remote control.

4. Diversified connections: Supports various interface forms such as clamps, flanges, threads, welding, etc. (such as DIN, SMS, ISO standards), suitable for DN15~DN100 diameter pipelines.

5. Pressure and temperature resistance: The working pressure can reach 1.6MPa (some models support 800psi), suitable for liquid, gas, and steam media.

Application field

Food industry: Material transportation and flow control for dairy and beverage filling lines to avoid cross contamination.

Pharmaceutical industry: sterile isolation of purified water systems and bioreactors to ensure the cleanliness of drug production.

Fine chemical engineering: precise adjustment of weakly acidic alkaline media or high viscosity fluids to enhance process safety.

Selection and maintenance

The selection should take into account the characteristics of the medium (such as viscosity, corrosiveness), temperature and pressure parameters, and connection standards. It is recommended to regularly check the wear of the sealing ring and cooperate with a professional team for installation and commissioning to extend its service life. Non standard requirements (such as special materials or driving methods) can be customized, and detailed operating parameters need to be provided.
