This miniature Cartridge Needle VALVES has been developed for precise flow adjustment in an extremely compact package. It can be used to control mini-cylinders, nozzles, timing circuits, filling heads, etc. Cartridge valves in concert with a manifold offer a smaller envelope, reduced assembly time and fewer parts. O-ring seals throughout the valve insure a leak proof installation. The device allows precise flow control due to approximately 21 threads per cm adjustment and three degree taper of the needle. The adjusted flow remains stable even during temperature fluctuations as the needle and valve seat are both manufactured from stainless steel. Maximum inlet pressure is 20.68bar. The valve controls flows from 0 to 1SCFM at 3.4bar. The miniature Cartridge Needle Valve is fabricated entirely from stainless steel and is available with a wide variety of elastomeric seals to allow excellent corrosion resistance, fluid compatibility and thermal resistance.
