The revolutionary design of the Tideflex ® Series 39F Inline Check Valve provides superior back - flow prevention. This unique “duck bill” design eliminates costly backflow from oceans, rivers and streams and is the ideal valve for pump stations. The Series 39F uses proven Tideflex ® Check Valve technology that provides low cracking pressures, low headloss and the ability to oper - ate in the harshest of conditions. The flexible rubber check valve resists clogging and buildup of debris and it is available in several differ - ent 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 Division of Red Valve,Inc.

2. INSTALLATION 1. INSPECTION OF VALVE: Inspect the body and mating flanges for signs of dam - age. 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 flanges. This gasket is formed from 1/8" thick rubber and seals the area between the ID of the body flange and the inside of the bolt circle. The body flanges are serrated. Should the valve need to be dismantled, new 1/8" thick gasket material must be obtained and in - stalled between the body flange 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 flanged 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 flange is supplied by others. 1. INSTALLING FLANGE BOLTS: Insert the bolts and tighten in a star pattern. T ighten all bolts uniformly so as to distribute pressure evenly around the flange. 2. VALVE ORIENTATION: When the Series 39F is installed in a horizontal pipeline, the bill of the internal Tideflex ® Valve should be vertical. 3. EXTERNAL VALVE SUPPORT: V alve supports must be supplied at the locations and dimensions shown on the submittal drawing. The sup - ports 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 Tideflex ® Valve to open and discharge the flow media. Reverse differential pres - sure with cause the Tideflex ® Valve to close preventing back - flow. 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 Tideflex ® Check Valve sleeve is fabri - cated based on the maximum line and backpressure. Back - pressure 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 Tideflex ® Upstream Body Body Flange Clamps Upstream Flange Body Flange Lifting Lug Drain Plugs or changed in any way, it could affect the normal operation of the valve. Consult the factory with the new system specifi - 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 P ARTS WITH PRES - SURE 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 T ideflex ® Check V alve should be periodically inspected for damage, wear , or entrapped solids in the bill.

3. 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 Tideflex ® 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 flanges. C. Remove valve from the line and place on a solid, flat 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 flange bolt holes, as this may damage the flange. E. Slide the upstream body half and body out of the down - stream half. Place it on wood beams or another soft surface with the upstream flange resting on the wood beams and the Tideflex ® Valve pointing vertically upward. Take care not to damage the flange. CAUTION: The internal T ideflex ® Check Valve is clamped to the upstream body half. It must be pulled out horizontally until the internal Tideflex ® Check Valve is clear of the plate. Do not attempt to lift the plate vertically. Damage to the Tideflex ® Valve could occur. NOTE: Use the "T ideflex ® All-Rubber Check Valve" IOM for proper handling, storage, and installation instruc - tion for the Tideflex ® Check Valve. F. Remove the bolts that are used as pins in the T ideflex ® clamps. G. Loosen and remove the clamps. H. Lift the T ideflex ® Valve off of the pipe stub. Install the new Tideflex ® 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 T ideflex ® 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 flanges. Attach 1/8" thick gasket material to the downstream body flange and fill the area between the ID of the flange and the inside of the bolt holes. Overlap any seams. L. Slide the upstream body half, with T ideflex ® Valve in - stalled, 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 V alve 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 con - tacting the check sleeve or flanges to prevent possible damage. 3. Store this manual with the valve so that it is readily avail - able at the time of installation. TROUBLESHOOTING GUIDE SYMPTOM: VALVE WILL NOT CLOSE FULLY, OR CHECK • Possible obstruction in line. Inspect the valve for en - trapped foreign objects which may have lodged between the lips of the valve. • Ensure there is clearance below the Tideflex ® Check Valve and the bottom of the body. • Backpressure may not be sufficient to completely seal the valve. SYMPTOM: SLEEVE RUPTURE/INVERSION • Excess backpressure. Verify static backpressure and iden - tify possible surge pressure or vacuum pressure. SYMPTOM: LEAKING FROM FLANGES • Loosen and retighten bolts in a star pattern to ensure even pressure distribution around flange. • If leakage persists, replace flange gasket and retighten bolts in star pattern.
