Check valve

A valve, said valve comprising:

• a housing including an inner periphery surface defining a passage therethrough between an inlet port and an outlet port;
• a flange within said housing dividing the passage between the inlet and outlet ports into an upstream portion and a downstream portion, said flange extending circumferentially around the inner periphery surface of said housing, the flange defining a valve seat and having an inner surface defining a valve aperture;
• a poppet valve positioned in the downstream portion of the passage of said housing, said poppet valve including a valve disk and a valve stem extending from the valve disk towards the outlet port of said housing, the valve disk engaging the valve seat of said flange and moveable between a closed position to a fully open position, the valve disk being resiliently biased in the closed position against the valve seat to inhibit fluid flow in a first direction and allow fluid flow in an opposite direction to the first direction;
• and
• a guide removeably mounted on the inner periphery surface of said housing, said guide receiving the valve stem of said poppet valve as said poppet valve moves between the closed position and the fully open position.
