Glandular valves are designed to provided 100% shut-off gas ducts in continuous process plants. They provide complete isolation of auxiliary equipments, even against pressure excursions, allowing safe access for on-load inspection or maintenance, without having to close down the main process. Unscheduled emergency outages due to auxiliary equipment troubles can therefore be eliminated.

Used for bleeding gas to atmosphere in steel plants at the locations like furnace bleeder valves and dust catcher bleeder valves.

Effectively used to isolate the blast furnace from hot blast stove in integrated steel plants and pig iron making facilities using stoves. Also are used as a stove shut-off valve and back draughting valve. For a burner shut-off valve the same design is adopted with wedge arrangements to achieve isolation of gas lines from stoves.

Used for gas venting and pressure releasing applications in steel plants. It is back drafting, bringing down the hanging burdens and for furnace bleeding application.

Most systems, handling gas, require sections to be isolated for maintenance without shutting down the complete plant, hitherto, in sophisticated plants, this has been achieved by using gate valves. Fouress flap isolators now offer a simpler and cheaper solutions without any loss in sealing efficiency. In particular they require less external space and no special precautions against wind loading, can be supplied in modular form, allowing easy installation in large ducts, need no external supports when installed in vertical or horizontal ducts.

Safety and reliability have been a challenge in todays coal fired boilers at thermal power stations. FOURESS, in technical consultation with a few discerning customers have developed the perfect solution to the pressing problem of effective isolation of PF mills. This has been done with the ingenious concept of TWIN SEAL FLAP (TSF) Isolator, which guarantees 100% sealing efficiency for safe access to on-load maintenance of PF mills. Majority of the coal fired boilers in India use guillotine gates as Isolating equipment for PF mills. This technology has become out dated owing to its ill-equipped provisions. As such, Maintenance Engineers on the site face a host of problems, some of which are as follows : Existing guillotine gates do not use an effective sealing system. This results in leakage of gas to the downstream. High velocity coal laden gas further aggravates the leakage making it virtually impossible for maintenance personnel to take up on-load maintenance. Thus an additional blanking plate becomes essential.The entire operational area gets polluted due to transit leakage during operation of the guillotine gate.There is frequent failure of cylinder seals owing to heat radiation during operation.Guillotine gates often get jammed because of high temperature (warping), mainly due to narrow guides and improver bearings.To put an end to these crippling problems, FOURESS devised a simple product called TWIN SEAL FLAP (TSF), which provides the precise solution to the above mentioned drawbacks in guillotine gates The perfect Isolator, TWIN SEAL FLAP has provided its efficacy, ever since its first installation at Koradi Thermal Power Station in 1982 and subsequent installations of over a 100 units in a number of Thermal Power Stations in India.

Bombay Engineering Industries (BEI) is the leading manufacturer of Quarter turn gear operators with proven design and time tested indigenous technology backed by two decades of engineering expertise. These gear operators are flawless in turning the valve disc from Open to Close position and vice versa by 90 degrees. The output torque of these rugged, accurate and reliable quarter turn gear operators, range from 12 Kg-m unto 14, 000 Kg-m with suitable reduction designed for both Manual (M) and Motorised (E) operations.

Simplex fitted to the periphery of the blade is a series of flexible metallic looped and leaf-spring sealing elements. These seals are constructed of austenitic stainless steel or high nickel alloys, depending on the operating conditions. They are designed to seal against both continuous landing bars in the duct framework of the isolator and to provide a sealing margin of at least 30 mm. The metallic seals alone, give a sealing efficiency of 99.95% or better, on cross-sectional area. Duplex 100% tightness, required to ensure complete safety for maintenance personnel working in an isolated section, is attained by creating, with a small fan, an air barrier in the inter space between the two sealing surfaces. The pressure zone, set at approximately 50 mm. H2o above the expected duct pressure, does not pump them up. This sealing arrangement has the additional advantage that it provides an automatic venting arrangement if there is a sudden pressure surge. Thus if the first sealing surface pushed off, the second, nearest the isolated section, is pressed even tighter against its landing surface and the gases are vented to atmosphere through the fan.

BEI, A pioneer in GEAR BOXES poised to set trends by grindingPTFE lined low friction , low maintenance bearing Indian industry. Imagine the benefits this product can offer in selection of Gear boxes and actuators in valve business, by reducing friction at bearing contract area, wherever conventional Bush bearings are used. Needless to say, there are many application areas outside valve business like in Automobile linkages, Kingpin assembly, crane Boom foot, Mast pivot etc., Where the need for Low maintenance, Low friction Bearings can be addressed. PTFE LINED on MS, SS or BRONZE backing material in split bush formation, made to your exacting size requirements.

In an increasingly crowded world, the need for clean water concerns everyone involved in sustaining our quality of life into the twenty-first century. For more than four decades in the business of flow, Fouress has been the leader in providing solution to industry, municipalities using its knowledge and experience. Fouress commitment to filtration, has given it the basis to develop and provide comprehensive filtration solutions in association with its global partners. Filtration requirements are available down to 10 microns. Fouress offers a wide variety of filters, filter elements, materials, filtration ranges, sizes and methods, in both automatic and semiautomatic operating systems. Self-cleaning automatic filters are available as stand-alone equipments or as system packages that can handle virtually any flow rate. Our offered automatic self-cleaning strainers filters saves time and money that would otherwise be spent in cleaning and replacing cartridges, bags, & spray nozzles. These filters operate continuously without interrupting the main flow unlike sand filters and simplexduplex strainers.
