If the UniPro™ R with the Torque Limiting Valve Adapter won't open the soft seat/low torque valves, must I remove it from the dome every time I need to open them?


No. In this case, the UniPro™ R can be lifted straight up off the valve handle and swung out of the way to allow hand operation of the valve. No tools are required and no adjustments must be made to put it back on the valve handle. Just lift and swing. It's as easy as that.
