Abstract
There is disclosed herein a bulk container valve adapted for use with a bulk container having a tubular spout. The valve comprises a plastic housing having an interior chamber connecting a front port to a rear port. The housing includes a rear fitting about the rear port for connection to the spout, in use, and a front fitting about the front port. A generally spherical valve element is rotationally supported in the interior chamber for movement between a valve open position and a valve closed position. A handle includes a stem. The stem extends through an opening in the housing and is operatively mated with the valve element for selective rotation of the valve element. A fastener is secured to the stem within the interior chamber for securing the handle to the housing.
