A valve spring housing for use in an adjustable regulating valve device of a railway locomotive brake valve has a cylindrical body with first, second and third sections. The first section has an outer cylindrical surface of a uninterrupted curvature, which first section can be threadedly secured to a valve pin housing, a recess to accept the end of a spiral spring, and a first flange extending radially outwardly therefrom. The second section has a convex surface on the end thereof and a second flange extending radially outwardly therefrom. The intermediate section is disposed between the first and second flanges and seats a sealing member between the flanges. A torquing tool acceptor, such as a transverse passageway is provided on the second section to enable threaded securement of the valve spring housing to a valve pin housing of a valve pin assembly in assembling the adjustable regulating valve device.
