Air eliminator models cast without bypass ports cannot be
assembled with a limited-bleed valve plate at the Liquid
Controls factory. To retain the pressure control that a
limited-bleed valve plate provides, a limited-bleed tee
assembly must be installed in the piping between the air
eliminator and the valve (Figure 4).
Under normal circumstances, it is irrelevant which vent
port is piped to the valve and which vent port is piped to
the storage tank. However, there is one exception: air
eliminators with an increased venting capacity valve plate.
These include part numbers A8201, A8198, A8190,
A8188, and A8183. When installing these air eliminators,
the increased venting valve plate should be piped to the
storage tank, and the limited-bleed valve plate should be
piped to the valve. The limited-bleed valve plate is easily
identified by the notch in the top of the plate (see below).
Piping Configuration
The piping configuration for each air and vapor eliminator series is shown in the

Electronic Valves
When using an electronic valve, product may become trapped between the vapor eliminator
and the valve.
