MECHANICAL JOINT VALVES
Clean the socket end of the valve and the plain end of the pipe. To assemble the joint use soapy water or an approved
pipe lubricant. Slip the gland and then the gasket onto the plain end of the pipe. Make sure the gasket is oriented properly.
If using HDPE make sure there is a pipe stiffener inserted into the pipe. Insert the pipe into the bell of the valve and then
press the gasket into the socket formed by the pipe and the valve. Insert the bolts and hand tighten the nuts. Evenly tighten
the bolts to the torque in table 2 while ensuring the gap between the gland and valve is even around the socket. Use a star
pattern when tightening the bolts. See AWWA C111 for further information.

MAINTENANCE
SERIES 816 BUTTERFLY VALVE MAINTENANCE
The AVK S816 butterfly valve requires no scheduled maintenance. The valve should be exercised regularly. To
exercise the valve, open and close through one complete cycle.
S767 ACTUATOR MAINTENANCE
The S767 actuator is shown in Fgure 1. The actuator is factory lubricated with Mobilux EP1 grease. The unit is factory
adjusted, lubricated, and sealed. No adjustment or lubrication should be necessary. If the gear box operates roughly, remove
the cover and inspect for wear. All moving parts should be coated with grease. If necessary coat all moving parts with Mobilux
EP1. Buried gear boxes should be packed 90% with grease.
