The Abrasive Flow Solutions (AFS) team celebrated the company’s first year of enterprise recently (March 2022) by hosting a two-day launch perform 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 part of the Group’s technique to increase its fluid expertise services in Africa.
“The AFS team works closely with our sister company BMG, to extend specialist companies, through 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. “Our specialists efficiently achieved their first challenge, which they set for themselves when the company was established – to enhance the quality of diaphragm valves, by extending service life and reducing the maintenance requirements of this range. This aim was achieved through onerous work and the implementation of advanced design applied sciences, supplies and coatings and is a superb tribute to our group.
“Important milestones over the last yr include the establishment of a brand new rubber lining facility, with the installation of autoclaves that have capacities of up to 10 m in length. In the rubber industry, autoclaves are used to vulcanise rubber products, which are not but steady dimensionally, by elevating warmth and pressure. An autoclave is much like an enormous oven, with extremely excessive temperature and pressure rankings, that make rubber elements stable and strong in dimension and shape.
“Another development is a model new pinch valve sleeve manufacturing facility inside our new rubber lining and sleeve manufacturing facility.
“We are now capable of manufacture all pinch sleeves, including high stress and pneumatic sleeves. AFS pinch sleeves are manufactured from the best quality rubber products, which might be equipped by Rema Tip Top. We have also made a major investment to increase our hydraulic urgent facility and through our new design and course of, we’re able 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 contains flanged, wafer, lugged, urethane lined and high-pressure knife gate valves.
“BMG also distributes a locally manufactured range of abrasion-resistant valves for Dual Products International. These merchandise embody pinch valves, new water air release valves, Resilient Seated Gate (RSV) valves and rotary disc sleeve valves. AFS has lately manufactured and factory-tested some larger DN seven hundred 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 by way of heavy slurries with out sticking. Wafer, flanged and high-pressure variants can be found.
“Our highly expert staff has a radical understanding of the processes the place valves are put in and is in a position to specify the right valves required for each application. We additionally help customers in solving the issues of adverse installations and purposes.
“To ensure optimum security, efficiency and the extended service life of every system, the selection of the proper industrial slurry valve is crucial. Valve selection relies on various components, together with the scale and shape of particles, stress, temperatures and chemical content material.”
This AFS portfolio is especially well-suited for use in harsh circumstances in numerous industries, together with mining, chemical and petrochemical, water and wastewater, energy production and agri-food industries. Important installations lately, have been in mining slurry, tailings dams, and acid pumping functions, which rely on plant availability and the safe operation of valves.
Another achievement for AFS is that ESG has recently achieved recognition as a Level 2 contributor to Broad-Based Black Economic Empowerment (B-BBEE), which suggests prospects can claim BEE procurement recognition of 125 percent towards all purchases.
