INSTALLATION
The CLINCHER may be installed for flow in either
direction. To ensure that a good installation is achieved,
follow standard piping practices. Pipe joints may be
sealed with either PTFE tape or pipe dope sealants.
When tightening valve to pipe, apply wrench to end
nearest pipe being worked.
After valve is in line, or before testing, tighten stem nuts
(16) according to the MAINTENANCE Section.

MAINTENANCE
1. General Maintenance consists of periodically tight-
ening the lower stem nut (16) to the values shown
in (Table 1). This is to compensate for the wear
caused by the stem turning against the stem seals
and may be done as follows:
A. Manual Valves - Loosen the handle nut (16)
and tighten the lower stem nut (16) to the
value shown in (Table 1). Retighten the han-
dle nut (16) to the same value.
B. Actuated Valves - When valves are connected
to an actuator, refer to the applicable actuator
mounting instructions (AMI) prior to adjusting
the stem nut.
2. Overhaul maintenance consists of replacing seats
and seals. A standard service kit consisting of
these parts may be obtained from your Jamesbury
Inc. Distributor. Refer to the REPAIR KITS/SPARE
PARTS Section.
