ABSTRACT:
A diaphragm operated regulator valve usable, e.g., for maintaining a preset gas pressure in a potable storage container, provides particularly effective at gas flow regulation as well as pressure regulation. The use of the word “fluid” as used herein can encompass both liquids and gasses. The valve includes a gas-balanced piston-tower diaphragm assembly that is freely supported, sealed, and operatively connected to a pressure-biasing adjustment. The diaphragm assembly permits axial movement relationships between valving channels or pathways, a valving-seal, and volume changes that take place in a low-pressure chamber. The valve 1) converts axial movement of the diaphragm into smooth transitional flow rates by varying the cross sectional areas of ingress and egress from an open valve position to a closed valve position and 2) has the ability to preset maximum flow rates.
