Abstract
A flow-control valve has a valve housing and a valve element in the housing rotatable about an axis through at most 360.degree. between a fully open position for substantially unimpeded fluid flow through the housing and a fully closed position for substantially no fluid flow through the housing and through intermediate positions for intermediate levels of flow through the housing. A spindle coupled to the element extends along and is jointly pivotal with the element about the axis. A handle fixed on the spindle is provided offset from the axis with a handle stop so that the handle stop orbits about the axis as the handle and spindle are rotated to adjust the valve. An abutment body or sleeve fixed on the housing adjacent the knob carries a housing stop that is radially deflectable on the abutment body between a normal position angularly engageable with the handle stop for limiting angular movement of the handle and spindle and a deflected position out of angular engagement with the handle stop and permitting unimpeded angular movement of the handle.
