Durco G4E Europa Valves Provide Bubble Tight Shutoff andISO Mounting

Europa Sleeveline

valves offer tighter shutoff

than other rotary design

valves and emissions con-

tainment equal to or better

than specially designed

severe service valves.

They are a best choice

for difficult chemical

applications and for

isolation of pumps,

tanks, reactors and other

critical equipment.

Unique tapered plug design assuresreduced turning torque and in-line sealadjustment for wear. ± 5 mm (3/16 in)adjustment; plug cannot bottom out.

Large seal area of the PTFE sleeve (as much as 10X greater than valves ofother design) delivers positive shutoffand extended service life. Sealing is bi-directional.

Available sizes: DN 15 (1/2 in), 20 (3/4 in), 25 (1 in), 32 (1-1/4 in), 40 (1-1/2 in), 50 (2 in), 65 (2-1/2 in),80 (3 in), 100 (4 in), 125 (5 in) and 150 (6 in).

Raised ribs, grooves and recessespositively lock sleeve in body.

Pressure class: PN 10-40

The G4E valve has been designedaccording to the criteria of TRB801No. 45 (AD-A4, DIN 3840 (calculation)and TRB 801 No. 45.

Face-to-face flange dimensions conform to EN 558-1, row 1 (ISO 5752, DIN 32021F1).

Rocker arm adjustment ensures positivesealing with the valve in-line.

Seal Adjustability

Reverse lip design of the PFA diaphragmprovides static and self-adjusting dynamicstem seal design. Backup stainless steeldiaphragm is optional.

DIN/ISO 5211 mounting pad facilitates actuation.

Rugged, heavy-duty body may be speci-fied in corrosion resistant stainless steels,nickel base and light reactive alloys.

Line sealingThe interference fit of the tapered plugwith the PTFE sleeve serves as the sealing surface. The sleeve totally surrounds plug ports and seals the circumference of the plug, top and bottom. There are no cavities to fill upwith product, and the seal area is largerthan in ball valves. Sealing is bothupstream and downstream.• Seal is totally independent of line

pressure.• There is no metal to metal

contact.• Valve remains free-turning throughout

its life and never requires lubrication.• Seal is adjustable.• Wiping action between sleeve and plug

provides for good slurry handling.

Static SealPFA diaphragm wedges against stem with an interference fit to seal against leakage toatmosphere or air leakage into valve on vacuum service.

Dynamic SealReverse lip diaphragm provides self-energizingdynamic stem seal where pressure activates thereverse lip to seal against the stem.

Positive stem sealA PFA diaphragm with reverse lip designprovides both static and self-adjustingdynamic steam sealing. This serves as a secondary atmospheric seal to the primary plug/sleeve seal. The stem seal is not normally exposed to full line pressure.

Positive in-line plug adjustmentThe unique design of the tapered plugallows a bubble tight, adjustable seal.The plug can be pushed deeper into thesleeve by two adjuster fasteners. Therocker arm gives one plane contact andresultant force down the centerline ofthe plug. Uniform adjustment of the twofasteners is not necessary.



New welded diaphragmThe integral thrust collar/alloydiaphragm is welded together for another line of defense against leakageto the atmosphere. The underside of themetal bellows-like diaphragm acts as anexpansion joint by allowing the PFAdiaphragm to adjust to plug movementand pressure changes.

The Hastelloy® C diaphragm provides animpermeable barrier to chlorine as wellas many other services.

G4EB Marathon™ValvesDeliver High Cycle, PositiveStem Sealing Durability

Unique stem-sealing designThe Marathon valve can be used withconfidence in chemical processingapplications where tight shutoff andemissions containment are priorityrequirements. As a bonus, its verydesign assures long life, high cycle performance.

Viton O-ringsA pair of Viton® O-rings prevents stemleakage while containing line pressure.They also protect the thrust collaragainst attack from atmospheric corro-sion. PTFE back-up rings firmly lock theViton O-rings in the stem grooves.

Optional Kalrez® O-rings are available for special services.

G4EB Marathon ValveViton O-Rings & Welded Metal Diaphragm Stem SealsSleeve & Diaphragm cut in four places

Passing the testIn a remarkable test, lab techniciansdefeated the PTFE sleeve and PFAdiaphragm, the G4EB’s primary andsecondary seals, by cutting both ofthem in four places. After 160,000cycles, the G4EB emitted less than 10parts per million of helium and showedno visible signs of stem wear.

The conclusionG4EB Marathon valve fugitive emissioncontainment is often equal to moreexpensive valves designed specificallyas severe or toxic service valves.

Durco firesealed valves have been successfully used on refinery applica-tions such as:• Isomerization • Gas plant• Blending • Sulfur plant• Light ends • Crude desalting

Fire Sealed Sleeveline

valves – both G4EZ and

G4EBZ models – incorporate

special Grafoil® packing

Grafoil® gaskets at the top

cap that reduce atmospheric

Durco Sleeveline valves have been firetested in accordance with the proce-dures set forth in API 607 Third Edition.They surpassed the external sealingrequirements of Section 4, Paragraph4.2, “Performance Requirements.”

G4Z fire sealed valves have beentemperature cycled to 204° C (400°F)*.They have provided performancesuperior to any other soft-seatedvalves available for temperaturecycling applications.

The Durco G4E Chlorine valve is built inaccordance with the recommendationsof the U.S. Chlorine Institute. This valve

is manufactured with a cast carbon steel body and a vented Monel plug for drychlorine service. It is cleaned,dried and packaged for delivery.

Vented plug design is alsorecommended for other cold

liquids such as anhydrous HCL.

Control Valves That AreCost Effective

Specially trimmed control

valves reduce noise,

cavitation and flashing while

improving flow and pres-

sure performance. Unique,

self-cleaning design pre-

vents particulate build-up

and clogging.

Technical Data forDurco G4E Valves

Testing assures Durco dependabilityDurco G4E valves are a revolutionarydesign. They incorporate all the bestdesign and construction improvementsthat have been made in soft-seatedvalves since Flowserve Corporation introduced the original non-lubricatedplug valve in 1950.

G4E valves have been extensively testedto ensure, insofar as possible, a com-pletely reliable process valve.

The unique reverse lip stem seal hasbeen tested from -46°C (-50°F) to 204°C(400°F) maximum, and with pressuresup to 4960 kPa (720 psig). For highertemperatures contact your FlowserveSales Office.

High temperature throttling tests at204°C (400°F) with pressure drops of1205 kPa (175 psig) have proven thesuperiority of the G4E valves over othersoft-seated valves. Ask your FlowserveSales Representative for specific testresults.

The valves have been temperaturecycled to 204°C (400°F), and have pro-vided performance superior to any othersoft-seated valve available for cyclicaltemperature situations.

We believe the G4E valve is the bestsoft-seated valve on the market today,and will outlast and outperform all competitive valves.

Pressure-temperature ratingsThe pressure-temperature ratings of all the materials above are based onmechanical property requirements cited in the latest DIN, ASTM or ANSIspecifications.

Valves may require adjustment toremain drop tight at the lower end oftemperature range when operatingbelow -17°C (0°F) or in extreme temperature cycles.

Manual valve turning torque*The turning torque of a PTFE sleevedplug valve is determined by two primaryfactors: setting of the plug to hold linepressure; and operating conditions(temperature, corrosion deposits, frequency of operation, etc.). All G4Evalves 150 mm and smaller are air tested at ambient temperature. The gasclosure test is in agreement with ANSIB16.34, 1988 for both the Class 150 andClass 300 valves. The average turningtorques for new valves are shown in thetable below.

SELECTION, INSTALLATION, OPERATION AND MAINTENANCEAlthough Flowserve can, and often does, provide general guidelines, it is obviously notpossible to provide application specific data andwarnings for all conceivable applications. Thepurchaser/end user must therefore assume theultimate responsibility for the proper selection,installation, operation and maintenance of theproducts. Read the appropriate IOM beforeinstalling, operating and repairing any valve. Thepurchaser/end user should train its employeesand/or contractors in the safe use of theFlowserve products in connection with the purchaser’s manufacturing process.
