Abstract: A water flow valve positioned within a waterline preferably just past a building's water meter. The valve compresses air bubbles into the water at the point where the water enters the meter, thus improving the accuracy of the meter reading. The internal passageway of the valve is non-linear and causing the water traveling therethrough to go through a plurality of turns. A blocking disk and spring are used to close off communication between a first portion of the internal passageway and a second portion of the passageway in a valve closed position. With enough water flow pressure the spring is compressed which causes the blocking disk to retract and allow water to travel through the passageway, while creating the backpressure in the waterline to collapse the air bubbles prior to the bubbles being read by the water meter. A laminar flow for the water can also be created which can reduce the wear and tear on the water meter possibly extending the useful life for the water meter.

The pressure receiving surface of the diaphragm can be made inactive by predetermined surface treatment. A layer for making the pressure receiving surface of the diaphragm inactive is formed by the surface treatment, and the pressure receiving surface of the diaphragm is held inactive with the presence of the layer.
