The Abrasive Flow Solutions (AFS) group celebrated the company’s first yr of business just lately (March 2022) by hosting a two-day launch function at its manufacturing plant in Benoni, Gauteng.
AFS, which specialises within the design and manufacture of slurry-related valves, was established by the Engineering Solutions Group (ESG) of Invicta Holdings Limited, as a part of the Group’s strategy to broaden its fluid know-how services in Africa.
“The AFS team works closely with our sister firm BMG, to extend specialist companies, by way of the design, distribution, supply and assist of a broad vary of slurry-related valves, including Klep diaphragm and wedge gate valves,” says Donald Morrison, General Manager, AFS. “ Massive achieved their first problem, which they set for themselves when the corporate was established – to improve the standard of diaphragm valves, by extending service life and lowering the upkeep necessities of this vary. This goal was achieved through hard work and the implementation of advanced design technologies, supplies and coatings and is a great tribute to our team.
“Important milestones over the past year embrace the institution of a new rubber lining facility, with the set up of autoclaves that have capacities of as a lot as 10 m in length. In the rubber business, autoclaves are used to vulcanise rubber products, which aren’t yet secure dimensionally, by elevating heat and pressure. An autoclave is much like a huge oven, with extremely high temperature and strain rankings, that make rubber parts secure and stable in measurement and shape.
“Another development is a new pinch valve sleeve manufacturing facility inside our new rubber lining and sleeve manufacturing facility.
“We are actually capable of manufacture all pinch sleeves, together with high strain and pneumatic sleeves. AFS pinch sleeves are manufactured from the very best quality rubber merchandise, which are equipped by Rema Tip Top. We have also made a significant funding to increase our hydraulic pressing facility and thru our new design and course of, we’re in a position to manufacture high-pressure diaphragms capable of pressures in excess of 20 Bar.
“AFS has enhanced the design and manufacturing of its slurry knife gate valve range, with dimensions ranging in diameter from a 50 mm unit to 1.5 m valves. The vary includes flanged, wafer, lugged, urethane lined and high-pressure knife gate valves.
“BMG also distributes a regionally manufactured range of abrasion-resistant valves for Dual Products International. These products include pinch valves, new water air release valves, Resilient Seated Gate (RSV) valves and rotary disc sleeve valves. AFS has recently manufactured and factory-tested some larger DN 700 hydraulically operated 20 Bar valves for a buyer in Europe.
“Recently launched Dual rotary disc sleeve valves comprise a complicated rotating gate valve with sleeve design, developed specifically for heavy abrasive and corrosive slurries and water and wastewater installations. This patented design permits the valve to cycle via heavy slurries with out sticking. Wafer, flanged and high-pressure variants are available.
“Our extremely expert staff has a thorough understanding of the processes the place valves are installed and is prepared to specify the correct valves required for every utility. We additionally help customers in solving the problems of inauspicious installations and purposes.
“To guarantee optimum security, efficiency and the extended service life of each system, the number of the proper industrial slurry valve is important. Valve selection relies on varied components, including the size and form of particles, stress, temperatures and chemical content material.”
This AFS portfolio is especially well-suited to be used in harsh situations in diverse industries, together with mining, chemical and petrochemical, water and wastewater, power production and agri-food industries. Important installations just lately, have been in mining slurry, tailings dams, and acid pumping applications, which depend on plant availability and the safe operation of valves.
Unheard of for AFS is that ESG has recently achieved recognition as a Level 2 contributor to Broad-Based Black Economic Empowerment (B-BBEE), which means customers can declare BEE procurement recognition of one hundred twenty five percent against all purchases.
