Materials for high-temperature and corrosion resistance
For high-temperature ball valves, selecting the right materials is crucial. This model uses two proven austenitic stainless steels:
- 1.4404 (316L)
- 1.4571 (316Ti)
These corrosion-resistant stainless steels offer high resistance to aggressive media and are suitable for elevated temperatures.
A key component of the seal is the silver-coated C-rings. These ensure a reliable seal even at high temperatures and under high pressure. The silver coating enhances the sealing effect and supports performance under thermal stress.
In addition, carbon bearings are used, which are characterized by their temperature resistance and mechanical stability.
Ball valve with metal-to-metal sealing for extreme conditions
A metal-seated ball valve is particularly suitable for applications where soft sealing systems reach their limits.
Thanks to the combination of:
- temperature-resistant materials
- metallic sealing
- optimized design
reliable operation is ensured even at temperatures up to 500 °C.
Applications: Chemical and pharmaceutical industries
This high-temperature ball valve is used in particular in:
- the chemical industry
- the pharmaceutical industry
This valve is a suitable solution wherever process reliability, tightness, and resistance to extreme temperatures are required.
Conclusion: Ball valve for high temperatures and the most demanding applications
The DN 100, PN 100 metal-seated ball valve combines suitable materials, a well-engineered design, and reliable sealing technology.
It offers a stable and durable solution for applications involving high temperatures, high pressure, and demanding media.
