5.5 Slow Close Assembly Installation
1. Remove the bolt and washer threaded into the valve stem. (If no handle is attached, install a direct
or manual handle.
2. Align the slow close assembly so that the two (2) spring pins on the slow close can be pressed into
the top of the valve body. There is a 90° slot on the slow close assembly that allows space for a
handle. Align the four (4) inner pins, so that they slide into the space between the handle and valve
stem (see picture below).
3. Secure slow close assembly with new 1.75” long hex bolt, p/n 116300-001. Torque the bolt to a
40 ft-lbs. [The original 1.00” bolt is no longer required.]
4. Open and close the valve several times to ensure the slow close assembly is working properly.
• An internal stop was designed into the slow close assembly and orientation of this stop may
prevent correct handle movement. If this occurs, remove the slow close assembly, rotate the
ball valve 90°, and reinstall the slow close assembly.
5. Do NOT remove the top four (4) bolts and attempt to service the slow close. There are no
serviceable parts in this assembly.
