Cla-Val X69H-C - Manual

The compact design of the Cla-Val
Model X69H-C Venturi is ideal for use
on stationary refueling carts and in any
system where space is an issue. Our
unique design eliminates external
plumbing. This feature simplifies instal-
lation, and maintenance, and also pre-
vents fuel spills that can occur when
exterior plumbing is hit or damaged.
The Model X69H-C Venturi can be
mounted in any orientation without
affecting performance. This allows the
Venturi to be located in tight spaces with
only the adjustment screw accessible
for servicing.
The Venturi body is an aluminum casting
featuring four ribs that extend from flange
to flange. These ribs give the Venturi
structural strength needed to carry piping
loads that can be generated by extreme
temperatures and pressures. The Venturi
features flat face flanges conforming to
ANSI 150 lb. Class.
The Model X69H-C Venturi is available
with six different throat diameters so that
you can select the Venturi with the
appropriate pressure drop and pressure
recovery requirements. Use the tables
and graphs below to determine the
appropriate throat bore diameter for
your application.
