Abstract:
A valve assembly comprising:a valve housing defining a cylindrical housing interior, the housing including a first tee part and a second tee part, each of the first tee part and the second tee part having a first open end, a second open end axially opposed to the first open end, and a side port located between the first open end and the second open end opening, the first tee part interconnected end to end to the second tee part to form part of the valve housing such that the second open end of the first tee part is coupled to the first open end of the second tee part, a valve seat disposed within the housing interior, a valve seat adjustment means interconnecting the valve seat and valve housing between the first tee part and the second tee part for selectively positioning the valve seat within the housing interior, a disc disposed within the housing interior and axially shiftable within the housing interior between a first position where the disc sealingly abuts against the valve seat thereby preventing flow communication between the side port and the second open end of the first tee part and a second position where the disc is spaced from the valve seat thereby permitting flow communication between the side port and the second open end of the first tee part, and actuation means sealingly fitted to the first end of the first tee part and operatively connected to the disc for selectively reciprocating the disc within the housing interior between its first position and its second position.
