Maintenance – Model LP Dry Valve Actuator
Refer to Figs. 7 and 8
1. If water constantly flows through the Model LP Dry
Valve Actuator and into the drain, there is a leak in the
seal of the Actuator’s seat.
2. Close the main valve controlling water supply (Fig. 7) to
the Deluge Valve and close off the air/nitrogen supply
to the sprinkler system. Close valve A (Fig. 7).
3. Drop pressure in the system by opening the ¼” angle
valve, valve E (Fig. 7), and remove the Actuator from
the system.
4. Remove all six bolts (#9, Fig. 8) holding the Actuator to-
gether. Clean or replace the facing plate assembly (#5,
Fig. 8) and seat (#3, Fig. 8).
5. Reassemble the Actuator, using a torque of 8 ft-lbs on
the facing plate nut (#7, Fig. 8) and 12 ft-lbs on the six
bolts (#9, Fig. 8). Use a cross-tightening pattern. Rein-
stall the Actuator. Set up the Model DDX Deluge Valve
as per the section of this bulletin entitle “Resetting the
Single Interlock Preaction System.”
