Thank you for choosing Tideex®.
The revolutionary design of the Tideex® Series 39F Inline
Check Valve provides superior backow prevention. This
unique “duck bill” design eliminates costly backow from
oceans, rivers and streams and is the ideal valve for pump
stations.
The Series 39F uses proven Tideex®Check Valve
technology that provides low cracking pressures, low
headloss and the ability to operate in the harshest of
conditions. The exible rubber check valve resists
clogging and buildup of debris and it is available in several
different elastomers. The Series 39F will not slam, thereby
minimizing noise and vibration.
The Series 39F is more economical than other large-
diameter check valve designs because there are no moving
parts that require routing maintenance.
• Simple Design
• Cost Effective
• Low Maintenance
• No Seats
• No Hinges
Series 39F Inline Check Valve
Installation, Operation and Maintenance Manual
IOM RV09.02-7
February 2023

INSTALLATION
1. INSPECTION OF VALVE:
Inspect the body and mating anges for signs of damage. Check
all inspection and drain plugs to ensure that they are securely in
place. The mating upstream and downstream pipes should be
plumb and square to the 39F.
2. GASKETS:
The Series 39F contains a gasket between the body anges.
This gasket is formed from 1/8" thick rubber and seals the area
between the ID of the body ange and the inside of the bolt circle.
The body anges are serrated. Should the valve need to be
dismantled, new 1/8" thick gasket material must be obtained and
installed between the body ange ID and inside of the bolt circle.
There is a large inspection port at the top of the valve that is either
plugged or blind anged at the factory, and two drain ports at the
bottom of the valve, also plugged at the factory.
Pipe tape is used to ensure a tight seal. Gasket for the mating
upstream and downstream ange is supplied by others.
1. INSTALLING FLANGE BOLTS:
Insert the bolts and tighten in a star pattern. Tighten all bolts
uniformly so as to distribute pressure evenly around the ange.
2. VALVE ORIENTATION:
When the Series 39F is installed in a horizontal pipeline, the bill of
the internal Tideex
®
valve should be vertical.
3. EXTERNAL VALVE SUPPORT:
Valve supports must be supplied at the locations and dimensions
shown on the submittal drawing. The supports ensure the valve
and mating pipe are not exposed to excessive stress due to the
weight of the valve and water in it. Note, the support shown is cas
concrete, but support weldments are suitable provided they are
manufactured to the dimensions shown on the submittal drawing.
OPERATION
The Series 39F operates solely on differential pressure. Forward
differential pressure will cause the Tideex
®
Valve to open and discharge
the ow media. Reverse differential pressure with cause the Tideex
®
Valve to close preventing backow. The Series 39F Check Valve is a
self-contained check valve for use in gravity fed and pumped systems
provided the pressure conditions are within what was supplied when the
valve was ordered. The Tideex
®
check valve sleeve is fabricated based
on the maximum line and backpressure. Backpressure in excess of
the supplied backpressure may damage or invert the sleeve and cause
failure. Should the conditions for which the valve has been designed
be altered or changed in any way, it could affect the normal operation
of the valve. Consult the factory with the new system specications to
determine if the valve will operate properly.

MAINTENANCE
1. INSPECTION:
The valve should occasionally be inspected for damage and wear.
The inspection period should be determined by the severity of the
service and environment. If the valve is periodically inspected and
preventative maintenance done, the valve will last longer and operate
better.
CAUTION: DO NOT REMOVE ANY PARTS WITH PRESSURE IN
THE PIPELINE.
There is a large inspection port
located at the top of the valve and
two drain plugs located at the
bottom of the valve. The internal
Tideex
®
check valve should be
periodically inspected for damage,
wear, or entrapped solids in the bill. All pressure must be removed
and the valve body should be drained prior to removing the
inspection plug. Following inspection of the valve, reinstall the
inspection plug (use pipe joint compound or tape) and tighten.

2.ELASTOMER SLEEVE REPLACEMENT
1. If the Tideex
®
valve needs to be replaced in the valve, the
following steps should be performed:
A. Remove internal pressure and drain water.
B. Remove bolts from mating anges.
C. Remove valve from the line and place on a solid, at surface
capable of supporting its weight.
D. Secure the upstream body half by suspending it from above. A
sling should be used around the pipe stub. DO NOT connect wire
or chain to the ange bolt holes, as this may damage the ange.
E. Slide the upstream body half and body out of the downstream half.
Place it on wood beams or another soft surface with the upstream
ange resting on the wood beams and the Tideex
®
valve pointing
vertically upward. Take care not to damage the ange.
CAUTION: The internal Tideex
®
check valve is clamped to the
upstream body half. It must be pulled out horizontally until the
internal Tideex
®
check valve is clear of the plate. Do not attempt
to lift the plate vertically. Damage to the Tideex
®
valve could
occur.
NOTE: Use the "Tideex
®
All-Rubber Check Valve" IOM for proper
handling, storage, and installation instruction for the Tideex
®
Check Valve.
F. Remove the bolts that are used as pins in the Tideex
®
clamps.
G. Loosen and remove the clamps.
H. Lift the Tideex
®
valve off of the pipe stub. Install the new Tideex
®
valve with the bill in the correct position (vertical after assembled)
onto the pipe stub. Ensure that the valve slides on the stub far
enough to hit the cuff stop. This will ensure the valve is properly
located.
I. Once the Tideex
®
valve is installed, locate the clamps on the cuff
and tighten. Rotate the "ears" of the clamp (90
o
for two clamps, 60
o
for three) to ensure an adequate seal around the cuff.
J. Use the four predrilled holes in each of the clamps as a template
and use a 1" drill bit to drill through the rubber cuff and through the
metal stub. Install the four 7/8" bolts in each clamp and tighten the
nuts to ensure valve is pinned to stub.
K. Wire brush the gasket material from both of the large body anges.
Attach 1/8" thick gasket material to the downstream body ange
and ll the area between the ID of the ange and the inside of the
bolt holes. Overlap any seams.
L. Slide the upstream body half, with Tideex
®
valve installed, into the
downstream body half. Line up the bolt holes. Install bolts and
tighten in a star pattern.
M.The valve is now ready to be reinstalled into the pipeline.
STORAGE
If your Series 39F Check Valve is to be stored for a period of
time prior to installation, the following storage guidelines will help
preserve your valve and ensure a trouble free installation.
1. Store in a clean, cool, dry area. Avoid exposure to light, electric
motors, dirt or chemicals.
2. Store valve in a manner to prevent other items from contacting the
check sleeve or anges to prevent possible damage.
3. Store this manual with the valve so that it is readily available at the
time of installation.
TROUBLESHOOTING GUIDE
SYMPTOM: VALVE WILL NOT CLOSE FULLY, OR CHECK
• Possible obstruction in line. Inspect the valve for entrapped foreign
objects which may have lodged between the lips of the valve.
• Ensure there is clearance below the Tideex
®
check Vvlve and the
bottom of the body.
• Backpressure may not be sufcient to completely seal the valve.
SYMPTOM: SLEEVE RUPTURE/INVERSION
• Excess backpressure. Verify static backpressure and identify possible
surge pressure or vacuum pressure.
SYMPTOM: LEAKING FROM FLANGES
• Loosen and retighten bolts in a star pattern to ensure even pressure
distribution around ange.
• If leakage persists, replace ange gasket and retighten bolts in star
pattern.
