Needle Valves

Cartridge Needle Valve provides precise flow adjustment.

Designed for incorporation into manifold assemblies, miniature Cartridge Needle Valve allows precise flow control due to 56 threads/in. adjustment and 3° taper of needle. Adjusted flow remains stable, even during temperature fluctuations as needle and valve seat are both stainless steel. With max inlet pressure of 300 psig, valve controls flow from 0-1 scfm at 50 psig. Metal-to-metal seal...
