Claims20
A water pressure regulator assembly, comprising:
- a valve body having a fluid passageway between a first fitting end, a second fitting end, a drain port, a bell base, and a gauge port;
- a bell coupled to said bell base;
- a spring positioned within said bell;
- a diaphragm coupled to said spring, said diaphragm coupled to a valve stem that is positioned within a stem opening in said bell base;
- a screen member positioned within said drain port, said screen member including a portion that is positioned in said fluid passageway adjacent to said first fitting end;
- a first fitting coupled to said first fitting end by a union coupling;
- a second fitting coupled to said second fitting end by a union coupling;
- a first check valve insert positioned in said first fitting adjacent to an internal shoulder in said first fitting, said first check valve insert permitting water to flow toward said first fitting end, but not permitting water to flow from said first fitting end out of said first fitting;
- and
- a second check valve insert positioned in said second fitting adjacent to an internal shoulder in said second fitting, said second check valve insert permitting water to flow from said second fitting end to said second fitting, but not permitting water to flow from said second fitting to said second fitting end.
