Abstract
A valve assembly having a body forming a bucket having a sidewall extending between an open end and a closed end along a bucket axis. A first conduit and a second conduit extend from the sidewall, wherein the first and the second conduits extend along a conduit axis that is perpendicular to the bucket axis. A frame inserts into the bucket along the bucket axis and includes a valve seat and a valve member biased against the valve seat. A guide is provided in the bucket between the closed end and the frame and extends along a guide axis between a first opening arranged in a first plane and aligned to receive fluid flow from the first conduit and a second opening arranged in a second plane and aligned to direct fluid flow through the valve seat. The first and second planes are not parallel to one another.
