High Purity Check Valves
Protection and Precision
Designed for high and ultra high purity processes, ensuring media integrity and control
FITOK check valves ensure safe one-way flow in low, medium and high pressure systems, including high and ultra-high purity processes, the semiconductor industry and alternative energy applications. With working pressures ranging from 10 bar to 4137 bar and temperatures between -79 °C and 649 °C, these valves offer tight shut-off and low cracking pressure for high sensitivity and maximum chemical compatibility. The range includes metal-to-metal seal, O-ring and all-welded designs, suitable for both compact systems and critical applications. FITOK check valves stand out for their wide variety of configurations, covering low pressure, high flow models, high sensitivity versions for exhaust lines and all-welded designs especially suited to high purity applications. In addition, the availability of multiple connection types provides great installation flexibility. All FITOK series deliver maximum reliability, safety and durability, making them the ideal solution to prevent backflow in critical applications.
