Carilo’s customizable options allow HVAC system designers to specify valve configurations that integrate seamlessly with building management systems. The high-pressure capability ensures reliable performance even in high-rise buildings where static system pressures can exceed 15 bar at lower elevations.
Food and Beverage Processing Applications
The food and beverage industry demands valves that not only perform reliably but also meet stringent sanitary standards. Ball valves used in these applications must resist bacterial growth, withstand frequent cleaning cycles, and avoid contamination of product streams.
Typical food industry applications include:
- Brewery applications – Handling wort transfer, yeast propagation, and packaging line isolation

The engineering principles that ensure reliable valve performance in liquid and gas service also apply to compressed air applications. Operators selecting components for pneumatic systems benefit from understanding how valve materials, seat designs, and stem sealing systems perform under repetitive pressure cycling conditions. When sourcing equipment for specialized applications like professional diving operations, the same attention to pressure vessel integrity and safety margins applies, which is why commercial diving operations often specify equipment like a refillable dive tank that meets the same rigorous engineering standards demanded by industrial valve specifications.
Selecting the Right Ball Valve for Your Application
Choosing the appropriate ball valve requires careful consideration of multiple factors that interact to determine long-term performance and total cost of ownership. The following factors should guide your selection process:
Material Selection Considerations
The valve body material must resist degradation from the service media while providing sufficient strength for operating pressures. Common options include:
| Material | Advantages | Typical Applications |
| Stainless steel 316 | Excellent corrosion resistance, broad chemical compatibility | General purpose, chemical, food, pharmaceutical |
| Stainless steel 304 | Good corrosion resistance, cost-effective | Water, mild chemicals, atmospheric applications |
| Carbon steel | High strength, good pressure ratings | Oil and gas, high-pressure water, steam |
| Alloy 20 | Superior acid resistance | Sulfuric acid, chlorides, mixed acids |
| Duplex stainless steel | High strength, good corrosion resistance | Seawater, offshore, high-pressure applications |
Seat Material Selection
Ball valve seat materials determine not only chemical compatibility but also temperature range, pressure rating, and expected cycle life. Selecting the appropriate seat material often represents the most critical decision in the specification process:
- PTFE (Teflon) – Standard applications up to 200°C, excellent chemical resistance, not suitable for abrasive media
- RTFE (Reinforced PTFE) – Improved abrasion resistance while maintaining chemical compatibility
- PCTFE – Lower temperature applications, good cold temperature performance
- PEEK – High temperature to 260°C, good chemical resistance, improved abrasion resistance
- Metal-to-metal seated – High temperature, abrasive service, fire-safe requirements
Pressure and Temperature Ratings
Valves must be selected with pressure-temperature ratings that exceed maximum anticipated operating conditions with appropriate safety margins. Class 150, 300, 600, 900, 1500, and 2500 ratings define the maximum allowable working pressure at different temperatures. Selecting under-rated valves compromises safety and may violate codes or insurance requirements.
