Claim 0:
1. A valve comprising:
a valve body including:
a first end and a second end spaced apart along a longitudinal axis;
a central portion defining an interior chamber that is disposed between the first end and the second end, wherein a first flow passageway of a fixed inner bore diameter is formed between the first end and the central portion and a second flow passageway is formed between the second end and the central portion, wherein the second end of the valve body includes a bore;
a removable seat ring defining a removable seat disposed in the bore and defining at least in part the second flow passageway, wherein a diameter of the removable seat matches the fixed inner bore diameter of the first flow passageway;
a locator interfacing between the removable seat ring and the valve body, wherein the locator includes a pin disposed in the valve body and an indentation in an outermost periphery of the removable seat ring, wherein a side of the pin fits partially within the indentation of the outermost periphery of the removable seat ring when the removable seat ring is installed within the bore at a corresponding rotational orientation;
a retainer ring that removably secures the removable seat ring within the bore by threadedly engaging a threaded annulus of the bore to create a seal between the retainer ring and the removable seat ring;
a stem rotatably supported by the valve body about a rotation axis; and
a disc coupled to the stem and rotatable within the interior chamber between a closed position, wherein the disc closes one of the first flow passageway or the second flow passageway via engagement with the removable seat ring, and an open position,
wherein at least one of the first flow passageway and the second flow passageway is completely unobstructed between the first end and the second end of the valve body when projected along the longitudinal axis.
