FITOK gas stick assemblies integrate a diaphragm valve/ball valve, a pressure regulator, and a pressure gauge into one stick to reduce site connections and achieve precise pressure control and fluid shutoff. FITOK gas stick assemblies, including the AGH series and AGL series, are both widely used in the semiconductor industry and so on. FITOK has been adopting strict specifications for materials, cleaning, and packaging processes to ensure product cleanliness.
AGH series high purity gas stick assemblies features include: For high purity gas systems such as the semiconductor industry; Integrate an ultra high purity diaphragm valve, an ultra high purity pressure gauge, and an ultra high purity pressure regulator into one stick with the diaphragm valve for shut-off function; Alloy diaphragm improves strength and corrosion resistance for long cycle life; T series tubular fittings optional for pressure gauge connection (customized lengths available); FC-03 Ultra High Purity Process Specification; Assembled and tested in ISO 4 / FED-STD-209E Class 10 Cleanroom; Manufactured from high purity stainless steel, wetted surfaces electropolished to an average internal surface roughness Ra of 10 µin. (0.25 µm); Ultra high purity cleaning with continuously monitored DI water ultrasonic cleaning system; and Double bagged with vacuum sealed polyethylene dust-free inner bag (inert gas filling optional) and sealed polyethylene outer bag.
AGL series general gas stick assemblies features include: Applicable for general gas systems and oxygen-enriched environments; Integrated from a ball valve, a regulator, and a pressure gauge; Alloy diaphragm improves strength and corrosion resistance for long cycle life; FC-02 Special Cleaning and Packaging Process Specification; Meet the requirements of ASTM G93 Level C specifying nonvolatile residues shall not exceed 6 mg/ft2, applicable for oxygen-enriched environments; and Double bagged with vacuum sealed polyethylene dust-free inner bag (inert gas filling optional) and sealed polyethylene outer bag.
