performed. Before servicing be certain shutoff valves are closed.
Removing Cam-Checks

Slowly open all ball valves to relieve air and water pressure.
Loosen bolts on groove coupler and remove groove coupler
and cover plate from valve body.
2. Remove #1 Cam-Check Assembly by using your hands to
unscrew (turn counter-clockwise) Cam-Check and remove
through top access port.
Do not use Cam Arm as a han-
dle to unscrew Cam-Check. If Cam-Check cannot be
loosened by hand, insert a long screwdriver between valve
body and Cam-Check (see figure 3). Gently apply pressure
against the Cam-Check until loosened. Finish unscrewing by
hand. Unscrew #2 Cam-Check (turn counter-clockwise) by
placing a long screwdriver across lugs and applying pres-

seat and clapper contact area for cleaning. To clean #2
Cam-Check, lift Cam Arm and hold in open position. Raise
clapper so that the end of the Cam Arm rests between roller
and clapper (figure 5B). Thoroughly clean the seat area and
clapper sealing surfaces of both Cam-Checks. Rinse Cam-
Checks and O-rings thoroughly. Inspect seats, clapper seal-
ing surfaces, Cam Arms, and O-rings for damage, nicks,
and debris. If not damaged, gently close the clapper. If dam-
aged, install a new Cam-Check assembly and/or O-ring or
shutoff disc.
4. Before reinstallation of check assembly, thoroughly clean
O-ring groove and lubricate with F.D.A. approved lubricant.
Insert and thread #2 Cam-Check first and then #1 Cam-
Check. #2 Cam-Check should be tightened by inserting a
long screwdriver between lugs to tighten firmly (see figure 2).
Do not over tighten. Tighten #1 Cam-Check firmly by hand
only. Replace cover plate, clean groove coupler gasket and
