A handle-operated flow control valve has handle portions which extend along opposite sides of a valve body. Aligned holes are formed through the handle portions and opposite body side portions. A double-looped support ring formed from resilient metal wire has end portions which extend through the aligned holes to pivotally mount the handle on the body. The loops extend in perpendicularly oriented planes and are configured such that either of them can be used to receive a support hook, whereby the handle-operated valve may be supported in either of two perpendicularly oriented planes by engaging the hook selectively with one or the other of the loops.
