Abstract:
A valve housing with integral downstream purge comprising:an integrally formed valve housing block; a main flow channel formed through the valve housing block; a distribution valve mounting surface formed upon the valve housing block; a distribution port formed in the valve housing block; an upstream distribution passage extending from the main flow channel to the distribution valve mounting surface; a downstream distribution passage extending from the distribution valve mounting surface and to the distribution port, the downstream distribution passage being in fluid communication with the upstream distribution passage for passage of fluid flow from the upstream distribution passage through the distribution port; a purge valve mounting surface formed upon the valve housing block; a purge port formed in the valve housing block; a first purge passage extending from the purge port to the purge valve mounting surface; and a second purge passage extending from the purge valve mounting surface to the downstream distribution passage, the second purge passage being in fluid communication with the first purge passage for passage of fluid flow from the purge port through the first and second purge passages into the downstream distribution passage.
