... very light tightening. The closing direction for all valves is clockwise. The replacement of the stuffing box seals can be done without stopping the installation thanks to the rear closure of the stem. The installation of cap valves on odorless gas systems (CFC, HCFC, HFC, etc.) is a safety measure in case of stuffing box leakage. The cap provides additional sealing as well as a means of leak detection. A small hole is drilled at its base under the seal.
