The revolutionary design of the Series 39 InLinheck Valve provides absolute backflow protec

tion. This unique duck bill design eliminatescostly backflow from oceans, rivers or stormwater and is the ideal valve for effluent diffuserystems.

The Series 39 Check Valve is available in a widevariety of elastomers and is designed to meetyour exact flow specifications.

Series 39 valves are constructed with 125# ANSflanges, which have the same drilling pattern as

ANSI 150# for ease of installation.

INSTALLATION1. NSPECTION OF VALVE:

Check flange faces of pipe for rough/damaged areas.ipeline flanges must be flat, properly spaced, and paral-

lel to achieve proper seal. PVC flanges may not sealproperly, and are not recommended by Tideflex ec -nologies. If PVC flanges are used, metal back up ringsshould be placed behind the PVC flanges in order to

prevent yielding. Typically, PVC flanges will yield beforehe valve will seal. TideflexTechnologies recommendshat pipeline flanges are serrated approximately 1/16" at

90o, in order to prevent the creep of the rubber flangeof the valve sleeve. Flanges with an oversizedI.D. can cut the sleeve flange, and are notrecommended with the Series 39 Valve. Grindor file any sharp edges of pipeline flange to preventdamage to the sleeve.

2. ASKETS:

The Series 39 Valve contains (2) gaskets between the

cast halves of the valve. As the gasket extrudes fromhe body, it may push the rubber flange away slightlyrom the cast body. DO NOT TRIM any excess gasket

material; it will seat itself after bolting the valve into thepipeline, thus providing a positive seal.

CAUTION: Do not use any sharp tools such as acrowbar or screwdriver on the rubber during installa-ion. Sharp instruments can damage the flange face and

cause possible leakage.

3. NSTALLING FLANGE BOLTS:

CAUTION: Only use flange bolts of the correct length sohat the bolts do not bottom out in tapped holes.

The use of bolts which are too long and bottom outcan crack or distort the body, causing permanent valvedamage. Tighten all bolts uniformly on both sides ofhe valve, so as to distribute pressure evenly aroundhe sleeve flange. (For complete information on bolting

dimensions refer to the back cover of this IOM ).

4.VALVE ORIENTATION:

The valve end with the rubber flange face should be in-stalled on the pressure side of the system. The bill areaof the rubber check valve inside the body must be in themaximum body width to allow the valve to close fully.The bill area should be installed facing downstream.

The casting flanges should be installed with a rubber fullace gasket between it and the downstream flange. The

inlet flange makes use of the rubber check valve flangeas the gasket (additional rubber gaskets are not re-quired on the inlet flange). The installation bolt torque onhe end flange bolts are listed in the table on the back

page of this IOM.

OPERATIONThe Series 39 Check Valve is a self-contained check valvefor use on low back pressure systems. All check valvesare built for each specific application. Back pressures inexcess of the maximum rated back pressure may invert thesleeve and cause valve failure.

Tideflex Technologies check valves are custom madeproducts intended for a specific application and have beendesigned to respond to criteria unique to that purpose,such as line pressure, minimum and maximum backflowpressure, and chemical compatibility. Should the condi-tions for which the valve has been designed be altered orchange in any way, it could affect the normal operation ofthe valve, and/or prevent the valve from draining complete-ly. Valves made to withstand high back pressure may notselfdrain completely.

NEVER...

Cut excess gasket.

NEVER...

Use sharp tools

on rubber sleeve.

MAINTENANCE.INSPECTION:

Valves should occasionally be inspected for damage andwear. e inspection perio s ou e etermine ythe severity of the service and environment. If valves areperiodically inspected and preventive maintenance done,t e va ve wi ast onger an operate etter.

CAUTION: Do not remove any valve parts or boltingwith pressure in the line. It is easy to inspect the

valve for obvious problems.

ELASTOMER SLEEVE REPLACEMENT:.A spare replacement check sleeve and gaskets shouldbe placed on order when this valve is placed in service.

2.When replacing the check sleeve in the valve body,carefully inspect the gaskets if they are damaged,or er new ones. o not trim t e gas ets; t ey s ouextrude a minimum of 1/8" after rejoining the bodyhalves.

.Do not clean the body end flange surfaces with roughabrasive wheels; the serrations will be removed andflange leakage may result. Do not use Permatex or RTVsilicone on the metal flange surface. These compoundswill fill in the serrations and flange leakage may result.

.Series 39 Check Valves ship from the factory withflushing port connections drilled, tapped, and plugged.n t ose app ications w ere c ec vaves an piping are

manifolded together, or if the percent of solids in theprocess may build up and pack around the outside ofthe check valve bill, it is recommended that the flushconnections be used to regularly purge the valve bodyfree of build-up or packing.

TORAGE If your Series 39 Check Valve is to be stored for a peri

of time prior to installation, the following storage guidelines will help preserve your valve and assure a troubleree installation.

. Store valve in a clean, cool, dry location. Avoid exposuo light, electric motors, dirt or chemicals.

2. Grease flange threads of body to inhibit rust or corro-sion.

.Store valve to prevent other items from contacting chesleeve or flanges to prevent possible damage.

. Store this manual with valve, so that it is readily availabat time of installation.

INSTALLATION NOTES FOR SERIES 39 CHECK VALVES

Note:If long, unsupported lengths of steel, plastic, or syn-thetic pipe are being used, the pipe may yield or sag due to the

valve weight. This may cause an inadequate seal between the

valve and flanges. Be certain sufficient pipe hangers are used

and properly located to support the total weight of the valve

and the process fluid.

Variables such as surface finish on bolt threads, type of anti-siezecompound used, and surface finish of the mating flanges all havean effect on the minimum torque required to obtain a leak tight

flange seal. Use of a high quality anti-sieze compound on all bolt threads is

recommended.

SERIES 39 CHECK VALVE WORKING PRESSURES AND FLANGE BOLTING

Torque values are suggested minimum values. Torque all flange bolts in a star pattern. First to 50% of tabulated

values, then re-torque to 100% of tabulated values. If greater

torque is required, continue re-torquing in increments of 50%of tabulated values.

D.When installing a check valveto a rubber, PVC, or any slickmating flange, we recom-mend that you install a metalserrated gasket between thetwo flanges to assist in theseal.

E.When bolting a check valveto a PVC or Synthetic matingflange, use a split back-upretaining ring, since the mat-ing flange will yield prior togenerating enough force onthe flange faces for a properseal.

F.Always use a star patternwhen bolting a check valve.
