Multi-function subplate mounted valve

A valve comprising:

• a lower valve seat defining a function port;
• an upper valve seat;
• a sleeve between said upper valve seat and said lower valve seat, said sleeve defining a sidewall that surrounds a poppet chamber, said sidewall defining a first port;
• a poppet received in said poppet chamber of said sleeve, said poppet having a sidewall, said poppet movable within said sleeve to selectively seal against said lower valve seat in a piloted position or to seal against said upper valve seat in an offset position, said sidewall of said poppet blocking said first port when said poppet is positioned in said offset position;
• a piston having a piston shaft, said piston shaft passing through said upper valve seat, said piston shaft affixed to said poppet for selectively moving said poppet into said piloted position and said offset position;
• a spring for biasing said piston so that said poppet defaults in said offset position against the upper valve seat for preventing fluid flow into the first port;
• a pilot port for supplying pressure for sliding said piston for compressing said spring and for moving said poppet away from said offset position to said piloted position so that fluid may flow into said first supply and out of said function port;
• wherein said upper valve seat defines a protruding central portion and a surrounding sloped section that defines a contact surface;
• and
• wherein said second end of said poppet defines a second beveled end surface for sealing contact with said contact surface of said upper valve seat.
