V-7 Valves - Installation
Installing the Linkage Assembly
Linkage assemblies are used with presets. The linkage
provides the connection between the valve handle and
the preset trip ring mounted on the mechanical register.
The linkage assembly is selected based on the meter/
register configuration. Linkage assemblies are available
in either straight or offset styles. These are listed in the
table below.
1. Mount the linkage assembly to the preset ring by
threading the threaded end of the ball joint into the
preset ring. Attach the linkage end to the ball joint
(Figure 13a).
2. Mount the other end of the linkage assembly to the
valve handle. Remove the retaining ring from pivot
stud on the valve handle to accomplish this.
3. Place the linkage bracket over onto the pivot stud
ensuring that the flat side of the linkage bracket is
facing the valve handle (Figures 13b & c). Secure
using the retaining ring.
Proceed with setting the dwell.
