V-15 & V-30 Valves - Installation
Retrofit Installations
Depending on the existing configuration, adding a V-15
or V-30 Valve may require modification of the outlet piping.
After the internal pressure is relieved from the system,
drain all the fluid from the flowmeter and accessories.
The outlet line can then be disconnected from the
flowmeter.
Installing the Valve
The V-15 or V-30 valve is installed on the outlet side of
the flowmeter. The valve may be installed in one of four
orientations as shown in Figure 5. Determine the
orientation desired and then attach the flowmeter using
the four bolts and washers provided. Tighten the bolts in
a crossing pattern.
Installing the Linkage Assembly
The handle and linkage assembly is provided with the V-
15 and V-30 Valves. The handle and linkage may need
to be repositioned depending on the valve orientation.
Refer to Figure 5 to determine the handle and linkage
positions based on the valve orientation.
The valve handle mounts on either side of the valve shaft.
Mount the valve handle to the valve shaft and tighten.
With the handle securely mounted to the valve shaft, the
linkage assembly can be connected to the preset ring
located under the mechanical register.
The linkage assembly connects to the preset ring via the
ball joint extension (Figure 6a). The ball joint extension
is mounted using the screw and nut provided.

Relieve Internal Pressure
All internal pressure must be relieved to zero pressure before
disassembly or inspection of the meter or any of the meter accessories.
Serious injury or death from fire or explosion could result from
maintenance of an improperly depressurized and evacuated system.
