In food, beverage, and dairy production processes, different product media, cleaning solutions, and process fluids typically need to be transported and switched within the same piping system. Inadequate valve sealing design can lead to mixing of different media, affecting product quality and increasing cleaning and maintenance costs.
The VTY Mixproof Sanitary Butterfly Valve is designed for the application needs of sanitary production pipelines. Through optimized sealing and fluid channel design, it achieves effective isolation between different media. Compared to traditional single-control butterfly valves, this product is more suitable for sanitary processing systems that require enhanced production safety and reduced risk of cross-contamination.
This valve features a stainless steel body and sanitarily treated internal flow channels to reduce media residue and support common cleaning requirements in the food processing industry. Different connection standards and configurations are available to suit various customer production system needs, facilitating compatibility with existing sanitary piping equipment.
Unique appearance design, easy disassembly. The unique design of the butterfly plate provides better sealing; leaks can be detected and drained through the drain port. Valves are available in manual or pneumatic operation, with intelligent controllers or proximity switches.
Specifications: DN40~DN100 2”~4”
Working Pressure: 0-10 bar
Working Temperature: -10°C to +90°C
Air Supply: Minimum 4 bar, Maximum 8 bar
VTY Mixproof Sanitary Butterfly Valve is manufactured with food-grade stainless steel materials to meet the hygiene requirements of food, beverage, and dairy processing systems.
The product contact parts are available in SUS304 or SUS316L stainless steel, providing reliable corrosion resistance and compatibility with sanitary fluid applications. SUS316L is recommended for applications involving higher corrosion requirements or frequent cleaning processes.
The internal and external surfaces are processed through precision machining and polishing procedures to improve surface smoothness, reduce media residue, and support hygienic operation.
The sealing components are selected according to different working conditions:
Standard seal: EPDM rubber, suitable for general sanitary applications and CIP cleaning environments.
Optional seals: Silicone (SILICON) and Fluorocarbon Rubber (FKM), available for applications requiring different temperature resistance or chemical compatibility.
Sanitary anti-mixing butterfly valves are widely used in the beer, beverage, food, pharmaceutical and fine chemical industries. They are most commonly used to isolate materials that require safe separation, as well as for single-unit CIP cleaning, or at the end of valve body components.
When selecting a Mixproof Sanitary Butterfly Valve, it is necessary to confirm the selection based on actual production conditions, including the type of media being transported, operating temperature, cleaning method, piping size, and connection standards.
Different media have different requirements for valve body and sealing materials. For example, dairy products and environments with frequent CIP cleaning typically require stainless steel materials with higher corrosion resistance and suitable sealing solutions.
VTY can provide suitable sanitary valve configuration solutions based on the piping parameters and application requirements provided by the customer.
As a professional manufacturer of sanitary fluid equipment, VTY possesses complete production capabilities, from machining, welding, and polishing to testing.
The company has a 13,000-square-meter production base equipped with 134 CNC precision machining machines, over 90% of which utilize Japanese MAZAK brand machining centers. It also has internal and external polishing production lines for pipe fittings, a professional welding department, and an independent quality testing laboratory.
During the production of the Mixproof Sanitary Butterfly Valve, VTY controls the product's machining accuracy and reliability through dimensional inspection, surface roughness inspection, hardness testing, and pressure testing, ensuring that the product meets the application requirements of sanitary fluid systems.
A mixproof butterfly valve is designed for applications where different fluids need to be controlled within the same pipeline system while reducing the risk of unwanted mixing.
In food and beverage processing, production lines often handle different products and cleaning fluids at different stages. A suitable valve design helps improve process control and maintain stable production conditions.
A standard butterfly valve is mainly used to open or close a pipeline and control fluid flow.
A mixproof butterfly valve is designed for more complex processing conditions where separation between different media is required. Its sealing structure provides additional protection during fluid switching operations, making it suitable for production systems with higher hygiene requirements.
The choice depends on the working environment, fluid characteristics, and cleaning requirements.
SUS304 is suitable for most food and beverage applications where general corrosion resistance is sufficient.
SUS316L provides better corrosion resistance and is commonly selected for applications involving frequent cleaning cycles, more demanding operating conditions, or higher hygiene requirements.
VTY can recommend suitable materials based on the customer's actual process conditions.
The sealing material should match the operating temperature, fluid properties, and cleaning conditions.
EPDM is the standard sealing option for general sanitary applications and provides good resistance to water, steam, and common cleaning processes.
Silicone and FKM are available for applications requiring different performance characteristics, such as flexibility, temperature resistance, or chemical compatibility.
Yes. The valve is designed for sanitary processing systems where regular cleaning is required.
The material selection, surface treatment, and sealing configuration should be considered together with the cleaning temperature, cleaning agents, and operating frequency to ensure long-term reliable performance.
Before installation, engineers should confirm the pipeline size, connection type, flow direction, operating conditions, and available installation space.
Proper installation helps ensure sealing performance, smooth operation, and easier maintenance during production.
