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.

The apparatus of claim 1, in which the piston further comprises a stem extending along the central axis adjacent the second end of the body. 3. The apparatus of claim 1, in which the valve seat is a ring-shaped member having an outermost cylindrical surface which contactingly engages an inner cylindrical surface of the body, and an innermost cylindrical surface which defines a central aperture in facing relation to the sealing surface of the piston. 4. The apparatus of claim 3, in which the valve seat further comprises a top surface normal to the outermost cylindrical surface, the top surface contactingly engaging a recessed shelf surface of a body, the junction of the top surface and the innermost cylindrical surface of the valve seat forming a corner surface which contactingly engages the sealing surface of the piston in a closed position. 5. The apparatus of claim 1, in which the first end of the body has a first interior body sidewall with a first diameter sized to nestingly receive the valve seat, and the second end of the body has a second interior body sidewall with a second smaller diameter sized to nestingly receive a piston stem of the piston. 6. The apparatus of claim 1, in which the valve seat has mirrored upper and lower sealing surfaces each adapted to be alternately presented in contacting engagement against the sealing surface of the piston to form respective bubble-tight seals responsive to inversion of the valve seat relative to the body. 7. The apparatus of claim 1, the valve housing having an inlet port, an outlet port and a medial chamber in fluidic communication with the inlet and outlet ports, the medial chamber defined by an interior annular sidewall and a lower inwardly directed shoulder surface, the interior annular sidewall greater than an outermost diameter of the body to facilitate insertion of the valve insert into the medial chamber for sealing engagement against the shoulder surface. 8. The apparatus of claim 7, further comprising a cap assembly comprising a cap member adapted to engage the housing to enclose the valve insert therein and a biasing member coupled between the cap member and the piston to provide a biasing force on the piston to maintain the valve insert in a normally closed position. 9. An apparatus comprising: a valve housing having an inlet port, an outlet port and a medial chamber in fluidic communication with the inlet and outlet ports, the medial chamber defined by an interior annular sidewall and a lower inwardly directed shoulder surface; anda unitary valve insert removably disposable within the medial chamber, comprising: a substantially cylindrical body comprising an annular wall with an outermost diameter less than the diameter of the interior annular sidewall of the medial chamber to form a gap therebetween, wherein at least one pass-through aperture extends through a medial portion of the wall;an annular valve seat nested within a first end of the body;a moveable piston disposed within the body having a sealing surface adapted to contactingly engage an inner annular surface of the valve seat to establish a fluidic seal; andan 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 that, when the valve seal is disposed in the valve housing, sealingly engages the lower inwardly directed shoulder surface of the valve housing. 10. The apparatus of claim 9, further comprising a cap assembly comprising a cap member which sealingly engages the housing to enclose the valve insert within the medial chamber and a biasing member adapted to exert a biasing force upon the piston to maintain the piston in a normally closed position to impede a flow of pressurized fluid between the inlet and outlet ports. 11. The apparatus of claim 10, in which the cap member further comprises a vent aperture which fluidically couples the interior of the cap member with a surrounding atmospheric environment and in which the valve insert further comprises an annular sealing member disposed between the piston stem and an interior surface of the body to provide a balanced pressure mode of operation. 12. The apparatus of claim 9, in which the valve seat is a ring-shaped member having an outermost cylindrical surface which contactingly engages an inner cylindrical surface of the body, and an innermost cylindrical surface which defines a central aperture in facing relation to the sealing surface of the piston. 13. The apparatus of claim 9, in which the first end of the body has a first interior body sidewall with a first diameter sized to nestingly receive the valve seat, the second end of the body has a second interior body sidewall with a second smaller diameter sized to nestingly receive the piston stem of the piston, and a top surface of the body has a recessed sidewall to form an annular groove to accommodate a second annular sealing member. 14. The apparatus of claim 13, further comprising a threaded cap member which engages the housing to enclose the valve insert, the cap member having a lower surface adapted to sealingly engage the second annular sealing member. 15. The apparatus of claim 9, in which the valve seat has mirrored upper and lower sealing surfaces each adapted to be alternately presented in contacting engagement against the sealing surface of the piston to form respective bubble-tight seals responsive to inversion of the valve seat relative to the body. 16. The apparatus of claim 9, in which the housing has a right angle valve configuration with the outlet port aligned at nominally 90 degrees with respect to the inlet port. 17. The apparatus of claim 9, in which the housing has in in-line valve configuration with the outlet port aligned with the inlet port. 18. The apparatus of claim 9, in which the housing is a first valve housing, and the valve insert is adapted for sliding removal from the first housing and sliding insertion into a medial chamber of a different, second valve housing. 19. The apparatus of claim 9, in which the valve insert is secured within the medial chamber at a position offset from a central axis of the chamber. 20. A method comprising: providing 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;inserting a piston into the body, the piston having a sealing surface adjacent the first end of the body and a piston stem adjacent the second end of the body;placing an annular valve seat into the first end of the body, the annular valve seat having a valve seat surface adapted to contactingly engage the piston to form a bubble tight seal; andinstalling an annular sealing member between an outer annular surface of the valve seat and an interior annular surface of the body, wherein the body, piston, valve seat and sealing member form a unitary valve insert adapted for insertion as a unit into a valve housing. 21.
