ABSTRACT:
The inline flow control device includes housing with a tubular portion coaxially aligned with the tubular portion of a fitting threaded to the housing. A piston has a bore extending therethrough with the tubular portions extended thereinto in axial spaced relationship, the fitting tubular portion mounting a valve seat to abut against a piston internal shoulder when the piston has axially moved relative to the tubular portions to a blocking position to block fluid flow through the device. The piston enlarged diametric portion bottom surface is in fluid communication with the piston bore in both of the piston positions but not in fluid communication with the body high pressure inlet when the piston is in its blocking position. A spring resiliently urges the piston in its blocking position. Two embodiments are pressure regulators while the third is a balanced valve.
