The invention relates to a control valve (1) which can be fastened in particular into a bore, which is designed with an internal thread (25), of a hydraulic door closer (20), with a basic body (3) which is adjoined by a control region (4), and with a thread (2) having a means for securing against rotation, wherein the thread (2) having the means for securing against rotation is screwed into the internal thread (25) of the bore. In order to provide a control valve (1) which is of simple design, wherein inadvertent displacement of the control valve (1) during operation is prevented, it is proposed that the means of securing the control valve (1) against rotation has a plastic layer on the threaded flanks of the thread (2), said plastic layer interacting with the internal thread (25) of the door closer (20). |
