Abstract
A sterilizer valve including a valve body with an inlet, an outlet, a vent, and a centerbore intersecting the inlet, outlet and vent. The valve further includes a valve stem having a shot chamber for holding a volume of sterilizing fluid, a fill passage having one end in fluid communication with the shot chamber and a second end intersecting the exterior surface at a fill port. The valve stem also has fluid communicating paths extending through the interior and disposed in an external surface of the valve stem. The valve stem is rotatably disposed in the centerbore of the valve body to selectively fluidly connect the shot chamber with the vent through the fluid communication paths upon the valve stem having different rotational positions with respect to the valve body.
