<p>The thermostatic valve head has a coaxial structure. A principal sleeve (1) is fitted over the valve body and located by a ring (2). An adjusting ring (3) is screwed over the sleeve. A thermostatic unit (4) is fitted inside the adjusting ring. The thermostatic unit displaces a valve mechanism (5) that moves vertically in the lower part of the valve against the action of a spring. A calibrating ring (6) occupies part of the space between the sleeve and the adjusting ring, and has a stop that sets its position relative to the adjusting ring. A limiting ring (7) fitted on the outside limits the travel of the adjusting ring. A cap (8) fits over the adjusting ring and locks the limiting ring in place. <IMAGE></p> |
