General
Description
The TYCO Model CV-1FR Grooved-
End Riser Check Valve is a compact
and rugged swing-type unit that allows
water flow in one direction and pre-
vents flow in the opposite direction.
A resilient elastomer seal facing on
the spring-loaded clapper ensures a
leak-tight seal and non-sticking opera-
tion. The Model CV-1FR Riser Check
Valves are designed to minimize water
hammer caused by flow reversal.
The Model CV-1FR Riser Check Valve
is furnished with grooved ends and
can be installed using GRINNELL
Grooved Couplings or GRINNELL
Figure 71 Flange Adapters. The Model
CV-1FR Riser Check Valves have been
designed with a removable cover for
ease of field maintenance. These valves
can be installed horizontally (with cover
in the upward position) or vertically with
the flow in the upward direction. Refer
to Figure 6.
To facilitate their use in wet-type auto-
matic sprinkler system risers, the
Model CV-1FR Riser Check Valves are
provided with threaded outlets for pres-
sure gauges and a drain connection.
They provide a more compact and eco-
nomical alternative to an alarm check
valve where a water motor alarm is not
required. Provisions must be made for
a local alarm using an approved flow
switch (not included).
The Model CV-1FR Riser Check Valve
is also Listed for use in conjunction
with the TYCO DV-5 Deluge Valve in
Preaction Systems under air pressure
without the use of prime water.
The Model CV-1FR Riser Check Valves
are a redesign for the Central Figure
590FR and GRINNELL Figure 590FR.
NOTICE
The Model CV-1FR Riser Check Valve
described herein must be installed
and maintained in compliance with
this document and with the applicable
standards of the NATIONAL FIRE PRO-
TECTION ASSOCIATION, in addition to
the standards of any authorities having
jurisdiction. Failure to do so may impair
the performance of this device.
Never remove any piping component
nor correct or modify any piping defi-
ciencies without first de-pressurizing
and draining the system. Failure to do
so may result in serious personal injury,
property damage, and/or impaired
device performance.
The owner is responsible for maintain-
ing their fire protection system and
devices in proper operating condition.
Contact the installing contractor or
manufacturer with any questions.

Installation
The Model CV-1FR Riser Check Valves
are to be installed in accordance with
this section:
1. The arrow cast on the Body must
point in the direction of the flow.
2. Valves installed vertically must
be positioned with the flow in the
upward direction.
3. Valves installed horizontally must be
positioned with the Cover facing up.
Refer to Figure 6.
4. Grooved-end pipe couplings used
with the Model CV-1FR Riser Check
Valve must be installed in accordance
with manufacturer’s instructions.
NOTE: Valves should be installed a
reasonable distance downstream from
pumps, elbows, expanders, reducers,
or other similar devices to extend the
valve life. Standard piping practices
call for a minimum of five times the pipe
diameter for general use.
