Precision and CleanlinessEngineered for critical sanitary processes, this tri-clamp valve allows for secure, hygienic connections perfect for industries where purity is paramount. The mirror-polished finish and PTFE seals minimize contamination risks, ensuring safe control of food-grade, acid, water, oil, or gas media.
Robust Stainless Steel ConstructionChoose from SS304, SS316, or SS316L grades to meet specific corrosion resistance and durability requirements. These materials guarantee longevity and reliability, even in harsh chemical environments or high-pressure applications.
Easy Maintenance and VersatilityThe three-piece design enables straightforward disassembly and cleaning, minimizing downtime. Suitable for temperatures up to 180C and pressures up to 10 bar, this valve adapts to a wide range of media and applications with standard two-way flow channels and tri-clamp ends.
FAQ's of SQK TC Coating Ball Valve:
Q: How does the SQK TC Coated Ball Valve maintain sanitary standards in food and pharmaceutical applications?
A: The valve features a mirror-polished stainless steel body and PTFE seals, which prevent microbial contamination and facilitate easy cleaning, making it ideal for food-grade and pharmaceutical processes demanding strict hygiene.
Q: What materials are used in the construction of this ball valve, and how do they resist corrosion?
A: Constructed from SS304, SS316, or SS316L stainless steel, the valve offers enhanced resistance to corrosion from acids, chemicals, and process media. The PTFE (Teflon) seals further protect against chemical attack and ensure a reliable seal.
Q: When should I choose a tri-clamp end connection for my system?
A: Tri-clamp (TC) connections are preferred in sanitary installations for easy assembly, cleaning, and removal, making them suitable for industries like pharmaceuticals, food processing, and breweries that prioritize hygiene and maintenance efficiency.
Q: Where can the SQK TC Coated Ball Valve be installed?
A: This valve is designed for inline mounting in piping systems handling water, oil, gas, acid, and food-grade media, making it suitable for pharmaceutical plants, chemical processing facilities, dairies, and beverage factories.
Q: What is the valve's operation process and leak-tightness class?
A: The valve operates with a quarter-turn lever handle for swift open/close action. It achieves Class VI (bubble-tight) leakage rating, ensuring zero visible leakage and optimal control over the media flow.
Q: Which port sizes and pressure ratings are available for this valve?
A: Port sizes range from 1/2 inch to 4 inch, while the valve withstands pressures up to 10 bar and media temperatures up to 180C, accommodating various pipeline dimensions and process requirements.
Q: What are the main benefits of using the SQK TC Coated Ball Valve in industrial applications?
A: Users benefit from high corrosion resistance, sanitary design, easy cleaning, reliable bubble-tight sealing, manual operation, and straightforward installation via tri-clamp connections, all of which contribute to efficient and safe process control.
