Diagrams of Common Valves and Parts 

 

The below diagrams depict common 2-way and 3-way ball valves and the handle styles are likely 
to be encountered on this machine.  Also, shown in the following diagrams are miscellaneous parts 
likely to be used by this machine.  These diagrams are for reference only and may not show all 
types and styles of ball valves and other parts. 
 
The 2-way ball valves are shown in the OPENED and CLOSED positions.  The 3-way ball valves 
are shown in both flow direction conditions (see arrows).  In some cases, a 3-way ball valve may 
be adjusted to a NEUTRAL position, 90 degrees from the positions shown below.  These 
NEUTRAL positions may or may not stop flow through the valves and should not be used as 
operating positions unless specified elsewhere in this manual.  In some cases this machine may 
contain a 3-way diverted ball valve which will appear identical to the 3-way ball valves shown 
below.  In the case of a diverted ball valve, the handle only turns 90 degrees (not 180 degrees) and 
there is no NEUTRAL position.
