V. INSTALLATION INSTRUCTIONS:
A. Valve Installation:
The 2900E ball valves sizes 1.5” through 3.0” are bi-directional and can be installed in
either direction. The 2940E 4.0” valve should be installed with the arrow on the body
pointing in the direction of flow except in a tank to pump application where the arrow
should be pointing towards the tank. The 2950E butterfly valves are bi-directional and
can be installed in either direction. The 2960E butterfly valves should be installed with
the seat towards the pressure source.
Motor/Gear Case Repositioning:
The 2900E ball valve and the 2960E butterfly valve gear cases may be installed in one of
four positions relative to the valves assemblies’ inlet as shown in Figure 1. There are two
possible positions for the gear cases used on the 2950E butterfly valves as shown in
Figure 2. Since these valves are bi-directional each position can be mounted two ways.
The valves shown in Figures 1 and 2 are in the fully closed position If installation
interference is encountered due to gear case position, the following steps will allow
simple repositioning of the gear case:
NOTE: Some older 2-1/2” ball valve end caps have stepped recesses on the valves’
mating surfaces. These stepped endcaps cannot be used with the 2900 valves.
Replace these endcaps with new flat surface endcaps.
