Flow Control Needle Valves (Unidirectional Flow)

Flow Control Valves

Flow control needle valves (unidirectional flow control valves) allow fluid to freely flow in one direction.  These carbon steel valves have a heavy duty body composition and a micrometer adjustment knob for accurate valve setting. An Allen Head lock screw locks the handle in place.  Our needle valves are rated to 5000 PSI and available in 1/4" to 1-1/4" NPT and SAE port sizes.
