MAINTENANCE AND REPAIR
Replacing D06G Cartridge
The working parts of the D06G Valve, including diaphragm,
valve seat, strainer, and disk, are all contained in a
replaceable cartridge. To replace the cartridge:
���
Close the supply valve and relieve the downstream
pressure.
���
Relieve pressure on the spring by loosening the locking
screw (do not remove) and turning the adjusting knob
counterclockwise until no resistance is felt.
���
Remove the bonnet (Fig. 3) by using the MT06A1009
or MT06A1017 Service Tool and turning
counterclockwise. Remove the spring and protection
washer (Fig. 4).
���
Remove the cartridge using two screwdrivers as levers
(Fig. 4). Remove the cartridge O-ring.
���
Remove the strainer cup (Fig. 5) using the MT06A1009
or MT06A1017 Service Tool.
���
Remove the strainer and strainer support. Remove the
U-seal.
���
Clean the inside of the valve and all the components.
NOTE:
Replace the U seal (provided in the repair kit)
for a complete cartridge repair.
���
Replace the U-seal by placing the U-seal on the
strainer support and pushing the assembly into place.
The U-seal open end must face the strainer support
(Fig. 7). Replace the strainer onto the strainer support.
���
Assemble the strainer cup O-ring onto the strainer cup
and insert the assembly into the body of the valve. Tighten
securely using the service tool. Do not over torque.
