Abstract

A valve assembly is disposed within a water supply line upstream of a water meter or other delivery location and is structured to eliminate or significantly reduce the passage of air there through to the upstream location. A valve body includes a sealing portion sealing disposed within the supply line and in interruptive, exposed relation to a path of fluid flow there through. One or more valve members are biased into sealing relation to a plurality of valve seat openings formed in the sealing portion. A sufficient, predetermined biasing force is exerted on the valve members to maintain them into a sealing orientation with the valve seats, thereby preventing the opening of the valve members until a sufficient water pressure is exerted thereon by a flow water, from which the air has been removed, along the path of fluid flow. As a result, air included within the water flow supply line will be compressed and/or displaced and substantially prevented from passing independently or mixed with the flow of water downstream of the valve body.

Claims
