ABSTRACT:
A fluid pressure regulator is designed with a removable cartridge in which all of the wetted parts of the regulator which are subject to wear by the fluid may be removed from the housing of the regulator without detaching the housing from the plumbing to which it is attached. The valve and valve actuator are designed so as to encourage relatively high velocity fluid flow there through so as to prevent clogging and settling of material therein. The valve actuator is also designed to produce divergent flow outwardly to the diaphragm perimeter preventing clogging and setting of material therein.
