ABSTRACT:
An apparatus for sampling and draining media from a vessel or reactor is described. The apparatus comprises: (a) a valve body with a generally longitudinal axis extending therethrough; (b) a moveable disc assembly positioned within a central channel of the valve body; (c) a valve operating rod extending within the valve body along its longitudinal axis; (d) a piston actuator assembly for positioning the disc assembly along the central channel; and (e) a sampling port extending away from the valve body. The valve body comprises the central channel, which has an upper end communicable with a port in the wall of the vessel or reactor and a side outlet which extends away from the longitudinal axis of the valve body. The valve operating rod has an upper end which is communicable with the disc assembly. The piston actuator assembly is communicable with an opposite, lower end of the valve operating rod.
