Pulpingor more than 50 years, Engineered Valves has been manufacturing valves designed

specifically for pulp mill application. Weknow that processes for producing pulpstock almost always varies from machine tomachine and mill to mill. And those differentprocesses for producing pulp stock creates awide variety of valve needs and problemsinherent to the process. We’ve built a reputation on being a cutting edge supplierof valves capable of handling thick hot slurries that have a tendency to pack and de-water in any available crevice or crack.Our experience with these applications shows in our line of problem-solving valves for pulp mill service.

F

Fabri–Valve F39Applications: blow tank outlet,knotters, high density storage,and tower isolation

Offering assured shut-off andthrottling in abrasive and/or highsolids slurry service, the F39 isdesigned specifically to providedependable operation even in astatic column of solids.

• Optional flush and cleanoutports allow wash out of hardened debris

• Replaceable seats for positive shut-off

• Diamond port for throttling

Fabri-Valve C67 Bi-directionalKnife Gate ValveApplications: Stock lines, high den-sity stock, black liquor, filtrate,

pump and equipment isolation

The C67 unique, patented perimeter sealprovides bi-directional shutoff to reduceseal compression, eliminate leakage,seat pullout, galling and chest clog-ging common in unidirectional metalseated knife gate valves.

• Design eliminates grooves that collect material and prevent proper closing

• Bi-directional design prevents problems which occur when other valvesare installed backward.

2

Fabri–Valve C37 Knife Gate ValveApplications: stock lines, equipmentand pump isolation, and filtrate

The Fabri-Valve C37 is the work-horse of the pulp mill. This valve

meets or exceeds the MSS and TAPPIstandards for knife gate valves. Plus, the open seat area on the C37 allowsfor use in higher consistency stockwhere other manufacturer’s knife gatevalves fall short.

• Metal, D-Ring, or replaceable seat options

• All stainless steel or stainless bodywith carbon/ductile topworks

• Backing rings for reverse flow applications

Fabri-Valve C132 TransmitterIsolation ValveApplications: tank transmitter isolation.

The C132 is designed specifically to isolate an instrument transmitterfrom the tank so that it may bemaintained or replaced without interrupting the process or drainingthe vessel.

3

Fabri-Valve C133GLApplications: Green and whiteliquor, lime mud, causticizers – processing and storage

We engineered the C133GL tohandle the most difficult recoveryapplications. This valve utilizes ahigh profile nickel/TFE gate coatingand AFLAS seats to combat the cor-rosion, abrasion, and scale build-up

inherent to these services.

• Compatible with the Fabri-ValveScalebreaker actuator

• Valve does not discharge to atmosphere if seat fails

• Lower bonnet provides for multiple containment options

Dia-Flo Weir Diaphragm ValveApplications: causticizers

Offering corrosion resistant coatingsand diaphragms, plus a wide range oflinings, the Dia-Flo valves provide anexcellent, yet economical, barrier to

chemical attack and corrosion.

Recyclingt’s one of the most difficult valve applications in the paper industry –

the production of secondary fiber for papermaking. Producing clean fiber means the proper removal of contaminants like staples, wire, andother trash. And valves that perform for years in other applications may lastonly a few weeks due to the erosion created in the cleaning process. To meet these uncompromising tasks,Engineered Valves has been developingspecialty valves for difficult applications,like recycling, for over 50 years.

I

The Vortex Breaker is an extended-life component designed to

stop the centrifugal force created by the vortex thatmoves rejects, trash and con-taminants to the outsidewall of the cleaner. After

contaminants are spun intothe valves, the Vortex Breaker

breaks this centrifugal motionand allows the rejects to fall into

the dirt trap.

• Stellite overlay

Stockprep&Papermakinghis is the stage that strongly influences the quality of the paper you produce –

preparing the pulp to be made into paper. By refining, cleaning, and screening, thestock is made ready to enter the papermachine. And at this step, chemical additivesas well as clays and other materials, may beadded to the mix. All of these processesdetermine the mechanical properties and finish of the final paper. Engineered Valvescan solve many of the problems found in this area of the mill.
