Double Eccentric Soft Seated Valves.Orton VF Series.

The VF Series design is basedupon the double eccentricconcept which minimises thecontact between seal and seatand thereby enhances the valveperformance, reducesmaintenance and extends thevalve life. These features makethe VF series ideally suitable formedium to large size pipelinevalves where maintenancecosts and cost of ownershipneed to be kept to a minimum.

Engineered for SuperiorPerformance.• Rigid and heavy construction• Contoured disc• Full RF or FF flanges• In-line replaceable seal• Up to DN 4000 (160”) size• Fully rated PN 25 Bar & ASME cl.150• Low pressure drop• Customised specifications

Body seat configurations

Efficient Leak - Free Construction.• BodyThe body in the Orton VF Series is a one-piece cast orfabricated design, providing the ultimate in rigidity and leakfree performance. The conical centered seat, welded, boltedor integral to the body retains a full face flange sealingsurface completely free of interruptions and assures aminimum reduction of the inside port diameter as well asproviding the maximum flow capacity. The body internalsurface can be rubber vulcanized or epoxy lined.

• Body seatThe body seat remains corrosion resistant to the effects ofthe pipeline media. Depending on the body material this isachieved by the following solutions:- integrally cast, for bodies in stainless steels, bronze or

other corrosion resistant alloys;- welded to the body internal, for bodies in carbon steel;- fully vulcanized body internal, for bodies in ductile iron or

cast / fabricated carbon steel.Integral replaceable seat options are also available.

• Seal ringThe heavy “T” section seal ring is designed to eliminate thepotential extrusion due to high shut-off DP or high flowvelocity. As a result of this design, the valve is capable ofproviding a full tight shut-off at pressures up to 25 bar.The seal ring compression is adjustable in order to obtainthe optimum sealing capability at differing pressure values.

• Disc and Shaft ArrangementAn inherently rigid design, the upper and lower shafts aresecured to the disc by pins, totally enclosed within the discand protected from aggressive media. For heavy dutyapplications a one-piece shaft is provided.The hydro-dynamically efficient disc profile improves flowcapability and reduces pressure drop and dynamic torque.

• Shaft bushingsLong length, self lubricating bearings manufactured incorrosion resistant alloy are provided. The bearingprotectors assure a very high level of immunity againstcontamination entries or solid particles, resulting in a longerservice life and minimizing maintenance.

• Shaft sealingA corrosion resistance bushing, housing O-Ring sealsensures a complete and reliable sealing of the shaft.An adjustable and replaceable packing is also availableupon request.

Double Eccentric Soft Seated Valves.Orton VF Series.

Orton combined non-return and on-offemergency shut down valves offer totalreliability for hydro-electric and conventionalpower plants.The VF series valve, controlled by acounterweight and hydraulic cylinder is thesafest, most reliable and cost effectivemethod to prevent damage to importantrotary machinery such as turbines andpumps.The valve is maintained in the open positionby the action of the hydraulic cylinder. Inemergency situations, the solenoid valve isde-energised, the counterweight overcomesthe cylinder and closes the valve.The hydraulic circuit is designed tocustomer specific requirements, enables thecylinder to act as a damper, controllingclosure speed, thus preventing dangerouswater hammer effect in the pipeline.
