The supervisory switch enclosure may be positioned with the conduit enclosure at various
angles so to better meet space requirements (see Figure 3). To reposition the conduit enclosure
angle, hold rotation on the hex adaptor fastened to the upper bonnet with the use of an open
box wrench. While insuring the hex adaptor remains fully threaded against the upper bonnet,
position the conduit enclosure to the desired angle. When completed the hex adaptor MUST
be fully threaded against the upper bonnet to insure proper function. If the hex adaptor
becomes unthreaded the supervisory switch will send an opened signal. Also ensure that the
manual handwheel may be fully closed without interference from the supervisory switch
assembly.
VALVE CARE & MAINTENANCE
URFA valves require minimal maintenance. However, a routine inspection and test program is
essential for any fire protection system to insure that it is in proper operating condition. NFPA
25, standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection
Systems should be consulted for a determination of required test frequency and methods.
Below is a summary of the required frequency of inspections and testing for pressure reducing
valves:
Valve Application
Inspection
Flow Test
Sprinkler System Pressure Regulating Control
