In an emergency, the valve can be closed with this device.

Opening limit stops are used to limit the opening stroke of the valve and are frequently referred to as "rate sets". The proper setting for limited valve opening is obtained by first removing the cover cap from the top of the unit and then turning the limit screw in a clockwise direction while observing the valve position indicator. The cover cap is then re-installed to prevent air leakage.
