General
Description
The TYCO Model CV-300B Grooved
End Swing Check Valves are compact
and rugged swing-type units that
allow water flow in one direction and
prevent flow in the opposite direction.
A resilient elastomer seal facing on the
spring-loaded clapper ensures a leak-
tight seal and non-sticking operation.
The Model CV-300B Check Valves are
designed to minimize water hammer
caused by flow reversal.
The Model CV-300B Grooved End
Swing Check Valves are furnished with
grooved ends and can be installed
using GRINNELL
Grooved Couplings
or GRINNELL Figure 71 Flange Adapt-
ers. These valves can be installed hori-
zontally, or vertically with the flow in the
upward direction (Ref. Figure 2).

Step 1. The arrow cast on the body
must point in the direction of the flow
(Ref. Figure 2):

valve with the large boss facing
either up or down, and the flow arrow
pointed left or right
Step 2. Grooved end pipe couplings
