A-CN seals: precision-engineered for axial pressure applications
In industrial applications where high pressure, extreme temperatures and aggressive media come together, the right seal plays a crucial role. However, it is often forgotten that not all C seals are the same.
A-CN seals occupy a special place within the Provecta range. These specialised seals are designed for applications where axial loads are combined with radial sealing surfaces — a configuration that entails specific design and manufacturing requirements.
Designed for axial loads
A-CN seals are usually installed between two concentric surfaces. A typical example is the seat of a ball valve, where a reliable seal is essential to prevent leaks and ensure the integrity of the system.
In such applications, the seal is subjected to axial loads, while the effective sealing takes place on a radial surface. This combination requires a seal that is designed and manufactured with extreme precision.
A challenging manufacturing process
The production of A-CN seals is considerably more complex than that of standard C-seals. This is because the radial sealing geometry requires an exceptionally high degree of precision.
Some crucial factors in the manufacturing process include:
- Perfect roundness and strict dimensional control
- Precisely tuned spring characteristics
- Controlled contact stress during axial compression
- Consistent and repeatable production processes
Even the smallest deviation can impact sealing performance. That is why the production of these seals requires in-depth expertise, advanced production techniques and a strictly controlled process.
Reliable performance in extreme conditions
A-CN seals are often used in high-pressure systems and high-performance valve applications, where reliability is of the utmost importance.
In these environments, seals must function under conditions such as:
- very high pressure
- extreme temperatures
- aggressive or demanding media
To guarantee optimum leak performance, these seals are often provided with a silver coating. This surface treatment improves sealing performance by reducing friction and creating a better sealing interface between the contact surfaces.
Expertise and process control
At Provecta, the focus is not only on the design of high-quality seals, but also on complete control of the production process. Thanks to years of experience and thorough process development, the team has the expertise to produce A-CN seals reliably, accurately and consistently.
The result is a seal that customers can rely on, even in the most critical applications.
