Abstract
A valve includes a set screw that is screwable into and out of a complementary female threaded opening in a valve part for changing a setting of the valve, for changing an adjustable flow restriction of the valve, in which the set screw includes a free outer end that projects outside the valve part, and a gripping part on its free outer end for a tool to be engageable thereupon. The free outer end of the set screw includes a male thread onto which a locking nut is screwed. A protective cap is provided for covering the free outer end, that includes a first cap portion with a rotation space for fitting freely rotatable over the locking nut, and a second cap portion with a complementary female thread that is screwed onto the male thread towards a locked position.
