High-pressure small valve steel / stainless steel for extreme applications
The Fig 108 shut-off valve is a high-pressure small-bore valve for precise shut-off in compact plants. It is suitable for liquids and gases under extreme pressure and temperature conditions. Ideal for test rigs, energy plants and chemical processes.
The material decides the temperature at the same pressure rating: 1.7335 up to +540 °C, 1.4104 up to +400 °C, 1.4571 up to +250 °C. PN 640 is the highest pressure rating in the Arndt range.
