pressure valve

Re my Trevi therm 300 (cp or ep???)(installed 1997). The pressure control shuts off ok but with only a little extra hand pressure the control can continue to be turned clockwise. It does not seem to have a solid stop position.

The on/ off handle connects to two gear slip cluches, and this is the reason that there is not a solid stop position.
