Installation Instructions

Product Description

The Model RCV Riser Check Valve has been designed
for use in the risers of wet type ire protection systems.
The
single clapper design features non-slamming
operation. The streamlined body and wide open clapper
design provide for low friction loss. This valve can be
installed in the vertical or horizontal position and the EPDM
rubber faced clapper provides a non-stick leak-tight seal
with as little as 1.5 meters (5 feet) of head. The removable
bonnet and clapper assembly provide easy access for main-
tenance, the drain is factory tapped at 1-1/4" or 2" NPT and
two bosses on each side are provided for pressure gauges
if required. The Model RCV check valve is rated at 20 bar
(300 psi) working pressure. Check valves are supplied with
our standard painted inishes, i.e. orange or RAL3000 red.
Optional inishes such as hot dipped zinc galvanized and
custom epoxy coatings are available.

Pipe Preparation

While pipe sizes are normally identiied by the nominal
size, always check the actual O.D. of the pipe and the ittings
to be connected, as in some markets it is customary to refer
to a different pipe O.D. with the same nominal size.
Sealing surface (pipe end to the groove) should be free
of indentations, projections, loose coatings, rust, etc. for
optimum sealing. Pipe ends should be cut square.
Prepare a roll or cut groove on the pipe end with a
SHURJOINT or other roll or cut grooving machine or tool in
accordance with the manufacturer's operation manual and
to the proper groove speciication. Refer to ANSI/AWWA
C606 for the groove speciications.
Installation Instructions
1. Locate the Arrow Mark on the valve body. The arrow
must point to the direction of low.
2. Position the check valve in place in accordance with
the low direction. In vertical installation, the arrow will
point upward.
3. Connect the check valve with two rigid couplings like
the SHURJOINT model 7771 or similar products of other
manufacturer's make. Please refer to the speciic instal-
lation instructions for the couplings being used.
Cautions
v Do not use the Grade E EPDM gasket for petroleum or
other oil services.
Always thoroughly lubricate the gasket and pipe end to
v
ensure optimum gasket sealing.
Excessive torque may lead to joint failure.
v
Uneven tightening may cause the gasket to be pinched,
v
resulting in an immediate or delayed leak.
