ABSTRACT:
The valve comprises an operating wheel connected by a connecting rod to an opening and closing member. The valve is sealed by a stuffening box fixed into the upper part of the body around the rod. The stuffening box has a polygonal head so that it can be screwed and unscrewed. However the head is not accessible using a conventional spanner so as to prevent a non-specialist form slackening of the stuffing box and avoid him risking an accident.
