API 603 AIL Stainless Steel Gate ValvesBolted Bonnet designThe API 603 family of AIL Stainless Steel Gate Valvesis an economic alternative to API 600 Stainless SteelGate Valves. They are available in flangedconstruction and in pressure ratings of ASME Class150 and Class 300.Gate Valves are of flexible wedge,outside screw-andyokeand bolted-bonnet construction.
Body and BonnetThe body and bonnet are cast with uniform section andgenerous radius fillets to prevent stress concentration. Thecastings are precision-machined for high performance.The gate valve body has a straight through port withoutrecesses except at the seat area. This ensures minimumturbulence, erosion and resistance to flow. Long integral guideribs in the body match with full-length guide slots in the wedgefo accurate alignment and guidance.
Flexible WedgeThe valves feature a one-piece castflexible wedge that minimises stressconcentration. Wedge flexibilityensures tight seating over a wide rangeof differential pressures andtemperatures. It also adjusts to slightmisalignments caused by pipelinedeflections and thermal deformation.The stem-to-wedge thrust is appliedclose to the wedge centre. Thisreduces lateral stem loading andprovides for more accurate wedgemovement.

Audco Butterfly Valves

The Audco Butterfly Valves are ideal for precision throttling and on-off applications, especially in lighter-weight piping systems, the Audco family of butterfly valves is often specified for its versatility. Outstanding throttling accuracy for process control is achieved through low-friction, erosion resistant sealing surfaces with very low operating torques.

A broad range of applications can be met via metal and soft-seated designs as well as lined versions for corrosive and hygienic applications.

AUDCO Butterfly Valves is a Wafer type Valve with an integrally-molded elastomer body liner. Designed to outperform loose

liners, AUDCO Butterfly Valves elastomer liner is molded directly in the body bore and vulcanized in-situ, making it last the entire

life of the valve. The result - a valve that requires no form of maintenance. A perfect FIT AND FORGET valve.

AUDCO Butterfly Valves is available in different combinations of body, liner and disc materials to suit a wide range of line fluids,

a size range of 50 to 600 mm, and a pressure rating up to PN 20. This permits its use in a wide range of applications making

AUDCO Butterfly Valves a truly versatile valve.

ADVANTAGES OF INTEGRALLY MOLDED LINER

LONGER LIFE VALVE

Integral molding permits maximizing the use of plasticiser

in elastomer formulation. This ensures a smooth surface,

thereby reducing friction between the disc and liner. In-situ

vulcanization imparts greater strength to the liner. Reduced

friction and high strength of the seat extend valve life.

SUPERIOR SEATING

AUDCO Butterfly Valves integrally-molded body liner is not

prone to stretching, which is the cause for fatigue in looselined

elastomers. Fatigue in elastomer results in excessive

wear and subsequent tearing of the liner. A torn liner can

be easily swept into the line causing extensive damage to

expensive, down-stream equipment. Though in valves with

loose liners the seat can be replaced, by the time it is done, the

line fluid would have caused some corrosion to the valve body.

This causes imperfect seating of the new liner, resulting in

leakages. These drawbacks are eliminated in AUDCO Butterfly

 

Valves integrally-molded liner design.

AUDCO Butterfly Valves has a gasket integral to the body

which eliminates the need for a separate gasket between the

valve face and companion flange. In addition, as the liner is

bonded to the body, it will not hang out or get pinched during

installation. Damage to expensive replaceable seats is thereby

 

eliminated.

STEM SEALING

In AUDCO Butterfly Valves the body liner incorporates flats

at the top and the bottom where the shaft passes through,

providing a wide sealing area. The secondary sealing is by two

'O' rings that are molded at the top and bottom of the seat,

which get compressed around the shaft. A weatherseal at the

top of the shaft prevents any ingress of foreign material into

 

the valve.In the AUDCO Butterfly Valve, the rubber liner incorporates flats at the top and the bottom where the shaft passes through, providing

a wide sealing area. This ensures the line fluid does not enter the stem area and get contaminated. The secondary sealing is by two

'O' rings that are molded at the top and bottom of the seat, which get compressed around the shaft

MaterialCast Iron
Packaging TypeBox

AUDCO is a wafer type butterfly valve specifically designed for corrosive services. The

body liner is formulated from Hypalon which is a synthetic elastomer having a chemical

inertness very close to that of PTFE, but at the same time having the resilience of rubber. This

design eliminates contact of the valve body and shaft from the line media. These valves find

application on lines carrying aqueous acids, alkali solutions and majority of inorganic salts. The

valve has a coating of epoxy paint capable of withstanding corrosive atmospheres.

AUDCO CLEANSEAL is a wafer type butterfly valve specifically designed for hygienic services. The

body seat is formulated from food grade EPDM or white Acrylo nitrile rubber, both synthetic elastomers

which do not impart any toxic substance, color, odor or flavor to the line media. This design

eliminates contact of the valve body and shaft from the line media. These valves find application on

Hygienic lines in food, dairy, beverages, pharmaceutical and other related industries. The valve has

a white epoxy paint for providing corrosion resistance. These valves are available in a size range of

50 to 300 mm and maximum pressure rating of 16 bar for EPDM and 14 bar for White Nitrile.

The  valve design incorporates a crevice free construction, which is a pre-requisite

for valves to be used on hygienic services. A smoothly streamlined elastomer lining with a fully

polished stainless steel disc ensures that there are no dead pockets or crevices in the valve. The

body seat and disc of the CLEANSEAL are contoured in such a way that it is impossible for any

line media to remain stagnant inside the valve. The wiping action of the disc ensures that the seat

is always maintained clean.

  • Some basic design advantages such as metal-to-metal seats and wide seating area, have made Audco Lubricated Plug Valves by Serck Audco the product of choice where the valve is operated in a difficult or dirty service and/or needs to be opened against high full Differential Pressure.
  • The Robust metal to metal seat ensure long valve life on any service, even in presence of solid particles in the line media.
  • Serck Audco Lubricated Plug Valves are available in Pressure Balanced design (Super-H) and Double Block And Bleed (PV & NPV).AUDCO Lubricated Taper Plug Valve has been successfully used in a variety of services because of its unique in-line maintenance capability. The AUDCO Taper Plug Valves are manufactured in sizes 1/2" to 12" and used in a variety of liquid, gaseous and slurry services. The tapered seating surfaces of the Body and Plug are not exposed to the line fluid when the valve is in the open position, so that the erosion and corrosion of the media are confined to the lesser important part of the Valve. The 'Super LoMu' Plug coating and the patented sealant provide low friction, low torque and easier operation of the Valve. Click here for catalogue
  • Tapered Plug Valves that Audco has developed while leading the market over the last 90 years. With the most typical applications found in natural gas, upstream hydrocarbon and slurries, this well-established design has proven its suitability on a range of demanding applications when zero leakage or bubble tight shut-off and reliability of operation are of prime importance.
  • Basic design advantages such as metal-to-metal seats and a wide seating area, along with competitive pricing, have made plug valves the product of choice when the valve is operated in a difficult or dirty service and/or needs to be opened against full differential pressure.
  • Standard Construction Audco Standard Type Valve The Audco Standard type valve has its integral operating shank at the large end of the taper plug. The plug is seated by means of forces applied through the gland packing housed in the cover which also seals the shank against leakage. To prevent damage to the packing where it would otherwise rub on the top of the plug, it bears on a metal shim which is clamped between the body and the cover. This reduces friction between the plug and the packing and also acts as a separate and very effective seal against leakage of the line fluid into the packing space.
