A bulk container valve is adapted for use with a bulk container having a tubular spout. A plastic housing has an interior chamber connecting a front port to a rear port. The housing is connected to a rear fitting about the rear port for connection to the spout, in use. The rear fitting comprises a cylindrical neck having an annular flange. A valve element is rotationally supported in the interior chamber for movement between a valve open position and a valve closed position. A handle is operatively mated with the valve element for selective rotation of the valve element. A one-piece, all plastic collar is received on the rear fitting. The collar comprises a tubular body including an inner threaded wall for threading on the spout and an end wall having a through opening. The through opening is larger than the neck and smaller then the flange whereby the end wall is captured between the plastic housing and the flange.
