critical when considering the set-
up of expensive equipment within a

Titan’s durable Suction Diffuser and Tri-ow
Control Check Valve are essential to protecting
and promoting the longevity of pumps. At the
same time, these two products are an economical
choice, designed specically to save space, energy,
and installation and maintenance time.
A Titan Suction Diffuser, while functioning as a
strainer to prevent foreign particles from harming
a pump, also has straightening vanes that reduce
turbulence in the ow and alleviate stress and
erosion on the pump. Titan manufactures each
diffuser with a mesh start-up screen that can be
removed after the diffuser's start up period. Just
one Titan Suction Diffuser replaces three products
in a typical pump set up: an elbow, strainer, and an
entry pipe.
The Tri-ow Control Check Valve is a spring-
loaded valve that can be adjusted from full ow
to complete shut-off. With a graduated position
indicator, Titan’s Tri-ow is easy to adjust and
control ow and its automatic shut-off helps
to prevent waterhammer. The Tri-ow is three
products in one as it takes the place of a balance
valve, shut-off valve, and check valve.

High quality protection for pumps
Directly mounted to the inlet side of the pump, Titan’s Suction Diffuser Strainer is
crucial for protecting expensive pumps. Serving as a strainer, it prevents unwanted
debris from entering pump. It also helps to increase the service life of the pump as
the straightening vanes on the outlet side of the diffuser help to smooth turbulent
ow before it enters the pump. An optional magnetic insert that attracts metallic
particles is also available. The suction diffuser has cast in supporting pads that t standard
support feet so an additional pipe saddle is not necessary.
Energy efcient and economical design
Titan’s Suction Diffuser takes the place of a strainer, reducing elbow, and an entrance pipe.
In addition to these specic parts, using the suction diffuser reduces the amount of piping,
welds, and bolts required in a traditional pump set-up. Not only is it economical as far as
the initial investment, but time and money are saved on installation and servicing. The
suction diffuser's minimal head loss, as a result of its large open area ratio, can yield
savings in energy costs for many years. Straightening vanes on the outlet side of the
diffuser help to maintain a smooth ow throughout the piping system decreasing pressure
loss.

Easy to service
The suction diffuser comes with a convenient mesh start-up screen that can be
removed after its initial introductory period, thus two screens are not necessary. Quick open knobs minimize down time while servicing and provide easy access to the
strainer. The standard NPT plug can be replaced with an optional blow down valve for
easy cleaning.

TF 21-CI ● Tri-ow Control Check Valve ● Flanged ● ANSI 125
Economical and convenient design
Titan’s Tri-ow Control Check Valve is three valves in one, replacing a
calibrated balance valve, shut-off valve, and silent check valve for a
simplied and inexpensive way to control ow from a pump. Flow through
the valve is adjustable from zero to full by the ACME rising stem. A
graduated position indicator on the stem provides an accurate check of the
valve’s position for throttling service, and a hand-wheel is provided with all Tri-ow control
check valves for ease of operation. The Tri-Flow also has a soft-seated, dovetail O-ring groove
ensuring a bubble tight seal in the closed position.
Quick closure to reduce water hammer
Silent shut-off is achieved via the fully automatic, spring assisted disc that closes near zero ow velocity when
functioning as a check valve. The soft seat and quick closure helps to prevent ow reversal, slamming, and
surges.

Minimal head loss
The valve’s body has a large body with at least a 2 to 1 ratio to connecting pipe. The disc's low cracking pressure
reduces the amount of energy required to open the valve.

SERVICING
The mesh start-up screen in the suction diffuser
should be removed after the initial start-up
period. Regular screen cleaning is necessary to
clear diffuser of foreign matter build up during
normal use and to maintain a low differential
pressure. An optional blow down valve is
available to assist in screen cleaning.
The Tri-ow can be adjusted as necessary
to control the ow. Regular servicing is not
required although some parts, such as spring
and O-Ring, should be inspected and replaced
as needed.
