The Abrasive Flow Solutions (AFS) team celebrated the company’s first 12 months of enterprise recently (March 2022) by hosting a two-day launch perform at its manufacturing plant in Benoni, Gauteng.
AFS, which specialises in the design and manufacture of slurry-related valves, was established by the Engineering Solutions Group (ESG) of Invicta Holdings Limited, as a half of the Group’s technique to broaden its fluid know-how providers in Africa.
“The AFS team works closely with our sister firm BMG, to increase specialist companies, by way of the design, distribution, provide and assist of a broad range of slurry-related valves, together with 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 corporate was established – to improve the quality of diaphragm valves, by extending service life and reducing the upkeep necessities of this range. This objective was achieved through hard work and the implementation of superior design applied sciences, materials and coatings and is a good tribute to our group.
“Important milestones during the last yr include the institution of a new rubber lining facility, with the set up of autoclaves which have capacities of as a lot as 10 m in length. In the rubber industry, autoclaves are used to vulcanise rubber products, which are not but secure dimensionally, by elevating heat and strain. pressure gauge 10 bar is much like a huge oven, with extraordinarily high temperature and strain ratings, that make rubber parts stable and strong in size and form.
“Another advancement is a new pinch valve sleeve manufacturing facility inside our new rubber lining and sleeve manufacturing facility.
“We are now in a position to manufacture all pinch sleeves, including high pressure and pneumatic sleeves. AFS pinch sleeves are manufactured from the very best high quality rubber products, which are equipped by Rema Tip Top. We have also made a big investment to increase our hydraulic urgent facility and thru our new design and course of, we are in a place to manufacture high-pressure diaphragms able to pressures in excess of 20 Bar.
“AFS has enhanced the design and production of its slurry knife gate valve range, with dimensions ranging in diameter from a 50 mm unit to 1.5 m valves. The vary consists of flanged, wafer, lugged, urethane lined and high-pressure knife gate valves.
“BMG also distributes a domestically manufactured vary of abrasion-resistant valves for Dual Products International. pressure gauge octa , new water air release valves, Resilient Seated Gate (RSV) valves and rotary disc sleeve valves. AFS has just lately manufactured and factory-tested some bigger DN 700 hydraulically operated 20 Bar valves for a buyer in Europe.
“Recently launched Dual rotary disc sleeve valves comprise an advanced rotating gate valve with sleeve design, developed specifically for heavy abrasive and corrosive slurries and water and wastewater installations. This patented design allows the valve to cycle via heavy slurries with out sticking. Wafer, flanged and high-pressure variants can be found.
“Our highly skilled team has a thorough understanding of the processes the place valves are installed and is ready to specify the proper valves required for each application. We also assist customers in solving the problems of inauspicious installations and purposes.
“To guarantee optimum safety, effectivity and the extended service life of every system, the choice of the correct industrial slurry valve is crucial. Valve choice is based on numerous elements, together with the scale and form of particles, pressure, temperatures and chemical content material.”

This AFS portfolio is particularly well-suited to be used in harsh circumstances 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.
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 implies clients can declare BEE procurement recognition of one hundred twenty five % towards all purchases.
