The Abrasive Flow Solutions (AFS) staff celebrated the company’s first year of business 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 strategy to expand its fluid know-how providers in Africa.
“The AFS staff works intently with our sister firm BMG, to extend specialist providers, through the design, distribution, provide and help 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 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 upkeep necessities of this vary. This aim was achieved through exhausting work and the implementation of superior design applied sciences, supplies and coatings and is a superb tribute to our group.
“Important milestones over the past 12 months embody the establishment of a new rubber lining facility, with the installation of autoclaves which have capacities of as a lot as 10 m in size. In the rubber business, autoclaves are used to vulcanise rubber merchandise, which are not but secure dimensionally, by elevating heat and pressure. An autoclave is much like a huge oven, with extraordinarily high temperature and stress scores, that make rubber elements stable and solid in size and form.
“Another development is a brand new pinch valve sleeve manufacturing facility inside our new rubber lining and sleeve manufacturing facility.
“We are now able to manufacture all pinch sleeves, together with excessive pressure and pneumatic sleeves. AFS pinch sleeves are manufactured from the best high quality rubber merchandise, which may be equipped by Rema Tip Top. We have additionally made a big funding to extend our hydraulic urgent facility and through our new design and process, we’re in a place to manufacture high-pressure diaphragms capable of pressures in extra 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. ไดอะแฟรม ซีล contains flanged, wafer, lugged, urethane lined and high-pressure knife gate valves.
“BMG also distributes a regionally manufactured vary of abrasion-resistant valves for Dual Products International. เพรสเชอร์เกจ embrace 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 bigger DN seven-hundred hydraulically operated 20 Bar valves for a customer in Europe.
“Recently launched Dual rotary disc sleeve valves comprise a complicated rotating gate valve with sleeve design, developed particularly for heavy abrasive and corrosive slurries and water and wastewater installations. This patented design allows the valve to cycle via heavy slurries without sticking. Wafer, flanged and high-pressure variants can be found.
“Our highly expert staff has an intensive understanding of the processes the place valves are put in and is prepared to specify the right valves required for every software. We additionally assist customers in solving the issues of difficult installations and functions.
“To guarantee optimum safety, effectivity and the extended service life of every system, the number of the proper industrial slurry valve is important. Valve selection relies on numerous components, together with the scale and form of particles, pressure, temperatures and chemical content.”

ไดอะแฟรม is especially well-suited for use in harsh situations in numerous industries, including mining, chemical and petrochemical, water and wastewater, vitality manufacturing and agri-food industries. Important installations just lately, have been in mining slurry, tailings dams, and acid pumping functions, which depend on plant availability and the secure operation of valves.
Another achievement for AFS is that ESG has lately achieved recognition as a Level 2 contributor to Broad-Based Black Economic Empowerment (B-BBEE), which suggests prospects can declare BEE procurement recognition of a hundred twenty five % against all purchases.
