Angled dual check valve

A check valve comprising:

• a valve body having a first fluid port and a second fluid port generally at right angles to one another, and an access port parallel to or aligned with one of said fluid ports;
• a removable closure normally closing said access port;
• and
• a poppet assembly insertable into and removable from said body through said access port when said access port is not closed and including a sleeve-like element of a shape generally the same as said access port and a size sufficiently small to move through said access port, a poppet valve secured to said sleeve-like element and slidable therein toward and away from a valve seat located about the other of said fluid ports, a biasing spring mounted on said sleeve-like element between said sleeve-like element and said poppet valve and normally biasing said poppet valve toward said seat, and a relief in said sleeve-like element through which said poppet valve may move between a portion substantially within the envelope of said sleeve-like element and a position outside said envelope and in sealing engagement with said valve seat slidably mounted to said sleeve-like element for movement toward and away from a valve seat located about the other of said fluid posts and having a valve stem extending away from said valve seat, said sleeve-like element including a hollow post slidably receiving and guiding said stem and comprised of an inner sleeve nested in an outer sleeve;
• said closure including a shoulder facing and embracing both said inner and outer sleeves at an adjacent end thereof and an annular projection extending into said inner sleeve to locate said sleeve-like element in said body.

• said stem having a cross-like section intermediate its ends and said hollow post having an interior side of partial cross shape matingly and slidably receiving said cross-like section of said stem.
