The Abrasive Flow Solutions (AFS) group celebrated the company’s first 12 months of business lately (March 2022) by internet 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 broaden its fluid technology services in Africa.
“The AFS group works closely with our sister company BMG, to extend specialist companies, by way of the design, distribution, supply and help of a broad range of slurry-related valves, including Klep diaphragm and wedge gate valves,” says Donald Morrison, General Manager, AFS. “Our specialists successfully achieved their first problem, which they set for themselves when the corporate was established – to improve the quality of diaphragm valves, by extending service life and lowering the maintenance necessities of this range. This aim was achieved by way of onerous work and the implementation of superior design technologies, supplies and coatings and is a great tribute to our group.
“Important milestones over the last yr embrace the establishment of a new rubber lining facility, with the set up of autoclaves that have capacities of up to 10 m in length. In the rubber trade, autoclaves are used to vulcanise rubber products, which aren’t yet steady dimensionally, by elevating heat and stress. An autoclave is much like a huge oven, with extremely high temperature and strain rankings, that make rubber elements secure and solid in dimension and form.
“Another development is a new pinch valve sleeve manufacturing facility inside our new rubber lining and sleeve manufacturing facility.
“We are actually in a place to manufacture all pinch sleeves, including excessive stress and pneumatic sleeves. AFS pinch sleeves are manufactured from the very best high quality rubber merchandise, which may be supplied by Rema Tip Top. We have additionally made a significant investment to increase our hydraulic pressing facility and thru our new design and process, we’re in a position to manufacture high-pressure diaphragms able to pressures in extra of 20 Bar.
“AFS has enhanced the design and production of its slurry knife gate valve vary, 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 products include pinch valves, new water air launch 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 customer in Europe.
“Recently launched Dual rotary disc sleeve valves comprise a sophisticated 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 without sticking. Wafer, flanged and high-pressure variants are available.
“Our extremely skilled group has a radical understanding of the processes where valves are put in and is able to specify the right valves required for every application. เกจวัดแรงดันต่ำ help customers in fixing the problems of adverse installations and purposes.
“To guarantee optimum security, efficiency and the extended service life of every system, the number of the correct industrial slurry valve is crucial. Valve selection relies on numerous elements, together with the dimensions and shape of particles, strain, temperatures and chemical content material.”

This AFS portfolio is especially well-suited to be used in harsh situations in diverse industries, including mining, chemical and petrochemical, water and wastewater, energy production and agri-food industries. Important installations recently, have been in mining slurry, tailings dams, and acid pumping purposes, which depend on plant availability and the safe operation of valves.
Another achievement for AFS is that ESG has just lately 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 % in opposition to all purchases.
