Numatics FC Series Flow Control with Female NPT Pipe connection on both ends.
These flow controls offer the highest "free flow" Cv of any flow control on the market! Giving your cylinders higher speeds in the non-controlled direction. The spring tensioned nylon piston opens fully allowing full flow to the cylinder and then returns to a precise, preset location to control exhaust to meter the speed of the cylinder. This feature makes the flow control self cleaning and does not require constant adjustment like other brands.
