Cavity Filled Ball Valves

Cavity filled ball valves for high viscosity medias

Cavity filled ball valves are ideal for materials like Polymer, Monomer, slurries etc where media is in form of fluids, semi solids and high viscosity. When media contains high sticking properties Cavity Free Ball Valve is an only solution to ensure valve’s longer life and consistent performance.

Cavity free Ball Valves are designed in such a manner that the cavities between the ball, body and stem are totally eliminated, thereby stopping process of media sediment build up inside the valve.

Frequently Asked Questions

What is a "cavity" in a ball valve, and why is it a concern?

In many standard ball valves, there are small empty spaces (or cavities) around the ball and stem area inside the valve body. These spaces can trap the process fluid when the valve is closed. For most water or air applications, this isn’t a major issue, but for certain sensitive processes, this trapped media can cause contamination, solidify, or corrode the valve from the inside.

So, what is a Cavity Filled Ball Valve?

It’s a specialized ball valve designed to eliminate those problematic empty spaces. The cavity around the ball is completely filled with a sealing material, creating a smooth, uninterrupted internal surface. This prevents any fluid from being trapped, making the valve self-draining and much easier to clean or sterilize.

Where are Cavity Filled valves absolutely necessary?

They are essential in industries where hygiene, purity, or media integrity are paramount. This includes sanitary processing in food & beverage and pharmaceuticals, handling of corrosive or hazardous chemicals, and processes involving sticky or viscous fluids (like resins, syrups, or slurries) that could solidify in a cavity and jam the valve.

What are the main benefits of choosing a cavity filled design?

The primary benefits are enhanced cleanliness, safety, and longevity. By preventing fluid entrapment, you eliminate a source of cross-contamination, bacterial growth, and internal corrosion. This translates to a more reliable valve, reduced maintenance, and compliance with strict industry hygiene standards.

Why choose IPC for Cavity Filled Ball Valves?

At IPC, we understand that details matter. Our cavity filled valves are engineered for maximum sealing integrity and reliability in demanding services. We use high-grade filling materials compatible with a wide range of process fluids to ensure the solution is as durable as it is effective.

How do I know if my application needs a cavity filled valve?

Ask yourself: Could trapped fluid cause contamination between batches? Could it solidify and prevent the valve from operating? Could it corrode the valve internally? If the answer to any of these is “yes,” then a cavity filled design is the right choice. Our technical team can help you confirm based on your specific media and process.
