23.01.2022 DUALs polyurethane sleeve range for their slurry knife gate valves: Extensive testing of polyurethane sleeves for the DUAL range of wafer and flanged slurry knife gate valves has recently been completed according to Justin Mirto of Dual Valves Australasia. Weve seen a growing number of customers specify polyurethane as their preferred sleeve material in our range of push-through style knife gate valves that we offer. This option has now been added to the standard range of ...sleeve materials stocked and available for use in both the wafer and flanged versions of DUALs slurry knife gate valves. The standard range of sleeve options now includes Pure Gum Rubber, Nitrile, EPDM, Viton, Chlorobutyl and Polyurethane. Comprehensive test work and site trials on all sizes up to DN600 have yielded extremely satisfying results in some of the worst abrasive slurry applications weve encountered so far explained Justin Mirto. End users reported excellent results in our valves operating up to 10 Bar working pressure and this has since proved to be an extremely cost effective solution in a number of our installations. This is an exciting development in our slurry knife gate valve range, and it fits in nicely with DUALs long standing philosophy of offering customers high performance with excellent value. See more

21.01.2022 eDART COARSE POPPET SAMPLER The coarse sampler has been specifically designed to sample coarse slurries, typically cyclone feed lines. This sampler can sample particles up to 15 mm in diameter. This sampler features a tungsten carbide piston plate and a polyurethane sampling chamber for increased wear resistance. The samplers are used for calibration of densitometers and... control purposes. In the retracted position the sampler is fully removed from the process stream to extend life expectancy. See more

21.01.2022 DUAL VALVES AUSTRALASIA OFFERS HYDROCORE U-CONE PIPE COUPLINGS DESIGNED FOR SPECIFICALLY FOR HIGH PRESSURE MINING PIPELINES The Hydrocore U-Cone coupling offers mine engineers a simple and economical alternative to traditional flanges for use on high pressure pipe systems. Pipes are joined simply by bringing the ends of the pipe with welded hubs together after inserting the seal, fitting the clamp set over the adjoining hubs and tightening the clamp bolts.... The external tapers on the hubs provide alignment while the clamp set pulls the hubs together, forming a simple but effective seal which comparable to similar rated conventional flange systems. Assembly and stripping times are faster than conventional flanges - the number of bolts to be tightened on U-Cone pipe couplings is far less than the number of bolts on a standard comparable flange system eg: a U-Cone DN100 250 Bar (25Mpa) rated coupling uses 2 bolts whereas a similar rated flange (ANSI/ASME B16.5 Class 1500#) would use 8 bolts. Storage/transportation costs are lower due to smaller footprint occupied by pipes with welded hubs compared to pipes with welded flanges. Flange diameters are larger than hub diameters. Hubs can be supplied full bore, with metallurgy to ensure weld compatibility with the pipe used, and are supplied prepared for standard butt welding to all pipes. Features and specifications: o Clamps are cast steel BS3100 Gr. 2 or equivalent as standard, with optional coatings available. o Hubs are St52 as standard, with other alloys available upon request for weld compatibility with the pipe system used. o Bolts used are Gr.8.8 or higher, electro-galvanized as standard. o Designed and tested per ASME B31.3 and ANSI/ASME VIII. o Available in various sizes with standard pressure ratings from 64 Bar up to 250 Bar (25Mpa): o 100 Bar (10MPA) rated: DN50 to DN500 o 160 Bar (16Mpa) rated: DN50 to DN400 o 250 Bar (25Mpa) rated: DN50 to DN300.

06.01.2022 Dual Valves Australasia introduces a new range of polyurethane lined knife gate valves (DULSKG) with 25 Bar pressure rating. Dual Valves Australasia recently completed the supply of 25 Bar rated polyurethane lined knife gate valves in a first for the company in Australia, according to Justin Mirto. Duals years of experience in using polyurethane compounds within their slurry valves allowed them to expand the range of one piece cast poly lined knife gate valves to now include... the 25 Bar CWP rated version. These valves were previously offered rated up to 10 Bar CWP. Dual Products manufactures the knife gate valves to MSS-SP-81 face-to-face dimensions; the valves feature repeatable bi-directional 100% drip tight shut-off, with the full port moulded polyurethane liner bonded to the single piece cast steel valve body giving extended service life over standard knife gate valves, especially in tailings and fly ash applications. The urethane lining extends over the flange face to serve as the valves flange gasket, eliminating any need for additional gaskets on installation. The valve tower features a provision for inductive proximity switches to be fitted without modifications to the tower superstructure. The valves are available with options for different methods of actuation, materials of construction and drilling patterns to suit the customers specific applications

02.01.2022 DVAs High Pressure Knife Gate Valve sleeves replace OEM sleeves after extensive site trials In another win for DUAL Valves Australasia, a West Australian alumina refinery has recently replaced a number of their 21 Bar rated OEM push-through style knife gate valve sleeves with sleeves from DUALs High Pressure knife gate valves - after reporting a tenfold increase in lifespan to date when using our DUAL DHPSKG sleeves in comprehensive site trials. We were advised that their ...21 Bar rated OEM knife gate valves were consistently failing after only four weeks in operation in the worst reported applications. A decision was taken by the refinery team to extensively trial a number of their knife gate valves retro-fitted with DUALs DHPSKG sleeves after we confirmed their suitability and dimensional fit explained Justin Mirto of Dual Valves Australasia (DVA). An initial set of four valves was retro-fitted with our DHPSKG sleeves, and these were installed in selected worst performing areas where the OEM sleeves were consistently failing after only four weeks in operation. At the time of writing this article, reports from the end user indicate the trial valves had been performing well for over 12 months. Encouraged by performance of the sleeves, the refinery embarked on a program to refurbish all the OEM valves with DUAL DHPSKG sleeves as and when they fail - in an ongoing exercise that has resulted in the refinery enjoying a new-found luxury: a reliable stock of rebuilt valves sitting in their stores awaiting deployment something that they had not achieved in years with the OEM. All the clichs apply - ownership costs are down, downtime has been slashed - and maintenance crew morale is up. Its been extremely satisfying to see these results unfold and recognised by end-users. DUALs long standing philosophy of offering customers high performance with excellent value have certainly paid off for this client explained Justin Mirto. We expect to see more end-users challenge the reliability and performance of their existing OEM push-through style high pressure knife gate valves as more reports like this gradually filter through the industry
