Titan’s Dual Plate Check Valves are designed to automatically
prevent back-flow in systems where it is desirable to permit flow in
one direction and prevent flow in the opposite direction. When the
pump starts and the downstream flow creates the required pressure
drop in the forward direction, the Dual Plates will automatically
open. When the pump stops and the flow ceases, the torsion of
the spring will automatically close the Dual Plates prior to flow
reversal. This creates a positive shutoff against flow reversal and
eliminates system surges and water hammer.

• Ensure Working conditions (pressure and temperature) are with in the specified capacity of the product being installed.
Please refer to the Engineering Specification Sheet for each
Check Valve model to determine these values.
• Inspect sealing surfaces that they are clean and smooth; no nicks or cuts. The pipeline should also be checked for proper alignment. Titan FCI
Check Valves should never be utilized to realign an
existing piping system.
• Make sure that the construction material of the Check Valve is
compatible with the media flowing in the pipeline. Additionally,
ensure that the service media is filtered to remove unwanted
debris prior to entering the Check Valve. If the service media
is not sufficiently clean, debris particles can prevent the Check
Valve from sealing correctly and degrade overall performance
overtime.

• For efficient function and improved service life, recognized piping standards stipulate placing Check Valves 5 to 10 pipe diameters from any
turbulence producing devices (elbows, pumps, tees,
expansions, reductions, and swages).

• When ready to install, remove any preservatives with solvent
dampened cloths. Remove any loose material and protective
packing material.
No.
• If the Check Valve is not required to be installed immediately,
it should be stored indoors in a clean, dry, consistent temperature environment. It is also recommended to utilize
the original shipping container and packing materials to properly store the Check Valve. If long term storage is required, a desiccant may be necessary. This would be based
upon the local, environmental storage conditions. Additionally,
rubber surfaces may require a thin film of grease. Rubber surfaces should never be directly exposed to sunlight or ozone
for extended periods. Please consult a Titan FCI Design
Engineer to assist in this determination.

• Visually inspect the Check Valve for any signs of damage including scratches, loose parts, broken parts or any other physical damage that may have occurred during shipment. If
damage is observed, immediately file a claim with the shipping
carrier. Check Valves that are damaged during transportation
are the responsibility of the customer. For information regarding Titan FCI’s warranty policy, please refer to the last page of this document.

INSTALLATION: Continued...
Titan FCI Dual Plate Check Valves are designed for steady flow
conditions and are not recommended for use in reciprocating
pump, compressor or other types of physical/thermal shock-load
applications. In this type of application, the Check Valve will not
perform efficiently and will ultimately fail.
Vertical Installation:
It is necessary to orientate the valve rib such that there
is equal loading on the Dual Plates. This is illustrated in
the diagram below. Additional pressure drop should be
expected due to the weight of the discs.
PRECAUTION:
Titan FCI Dual Plate Check Valves are designed to operate
properly for flow rates between 5 ft./sec. to 10 ft./sec.. It is not
recommended to exceed the maximum flow rate of 10 ft./sec.
or the minimum flow rate of 5 ft./sec..
In this position, the valve
rib is perpendicular to the
incoming horizontal piping
which creates an unequal
loading on the plates.
PRECAUTION:
A Titan FCI strainer should be installed ahead of the pump to
ensure protection and proper operation of the check valve and
the pump.

PRECAUTION:
A Titan FCI Dual Plate Check Valves can only be mated with
flat-faced pipe flanges per ANSI 16.5.
Horizontal Installation:
The valve rib must be installed perpendicular to the flow. This is
shown in the diagram below. The eyebolt or plug is located directly
above the valve rib can be used to correctly position the valve.
In this position, the valve rib
is parallel to the incoming
horizontal piping and
creates an equal loading
on the plates.

Step 3:
While supporting the existing pipeline, lift the Check Valve into
position. For large or heavy Check Valves, the appropriate material
handling equipment must be used in order to prevent injury and
possible damage to the Check Valve.
CAUTION:
When lifting the Check Valve, utilize the eye bolt or place slings/
chains securely around the valve body. Never lift the Check Valve
by attaching slings/chains to the trim/seat assembly. The trim/seat
assembly is not designed to withstand the weight of the unit.

MAINTENANCE:
Titan FCI Dual Plate Check Valves are designed to provide
trouble-free service and seldom require maintenance. If
removal of Check Valve is required for inspection, please
follow these steps.
Valve Removal
CAUTION:
Before removing the Check Valve from the pipeline,
the pressure inside the vessel must be reduced to
atmospheric via suction or venting. Failure to do so
may result in serious bodily injury.
CAUTION:
Before removing the Check Valve from the pipeline,
ensure that the media that is flowing in the pipeline
is known and any special handling precautions are
understood. Please review the Material Safety Data
Sheet (MSDS) for that specific fluid.
Step 1:
To remove the Check Valve from the pipeline, first isolate
the Check Valve by shutting off the upstream pump and
closing the downstream isolation valve. Drain the system
as much as possible.

Once proper installation has been successfully completed,
start the system gradually, at start up as well as after shut
down. This eliminates sudden shock to the Check Valve
and other equipment in the line.
