Insert for a fluidic valve assembly

摘要

Apparatus for controlling a pressurized fluid in a piping network, and method for making the same. In accordance with some embodiments, a substantially cylindrical body has an annular wall surrounding a central axis with opposing first and second ends and at least one pass-through aperture extending through a medial portion of the wall. An annular valve seat is nested within a first end of the body. A moveable piston is aligned within the body along the central axis, the piston having a sealing surface adapted to contactingly engage an inner annular surface of the valve seat to establish a fluidic seal. The body, valve seat and piston form a valve insert for a valve housing.

1. An apparatus, comprising:
a substantially cylindrical body having an annular wall surrounding a central axis with opposing first and second ends and at least one pass-through aperture extending through a medial portion of the wall; an annular valve seat nested within a first end of the body; and a moveable piston aligned within the body along the central axis, the piston having a sealing surface adapted to contactingly engage an inner annular surface of the valve seat to establish a fluidic seal, the body, valve seat and piston together forming a valve insert for a valve housing that is removable and installable as an intact unit; and an annular seal member nested within the first end of the body between an outer annular surface of the valve seat and an interior annular surface of the body to sealingly engage an interior shoulder surface of the valve housing.
