The Abrasive Flow Solutions (AFS) team celebrated the company’s first yr of business recently (March 2022) by hosting a two-day launch operate 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 part of the Group’s technique to expand its fluid technology services in Africa.
“The AFS staff works intently with our sister company BMG, to extend specialist providers, via the design, distribution, provide and support 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 requirements of this range. This aim was achieved by way of exhausting work and the implementation of superior design applied sciences, materials and coatings and is a superb tribute to our staff.
“Important milestones over the past yr embody the institution of a new rubber lining facility, with the set up of autoclaves that have capacities of as much as 10 m in size. In the rubber industry, autoclaves are used to vulcanise rubber merchandise, which are not but steady dimensionally, by elevating heat and strain. An autoclave is just like an enormous oven, with extraordinarily excessive temperature and stress scores, that make rubber components secure and solid in size and form.
“Another development is a new pinch valve sleeve manufacturing facility within our new rubber lining and sleeve manufacturing facility.
“We are now capable of manufacture all pinch sleeves, together with high strain and pneumatic sleeves. AFS pinch sleeves are manufactured from the best quality rubber merchandise, which are equipped by Rema Tip Top. We have additionally made a major funding to increase our hydraulic pressing facility and thru our new design and process, we’re able to manufacture high-pressure diaphragms capable of pressures in excess 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 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 embrace pinch valves, 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 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 specifically for heavy abrasive and corrosive slurries and water and wastewater installations. This patented design allows the valve to cycle through heavy slurries without sticking. Untold , flanged and high-pressure variants can be found.
“Our extremely expert group has an intensive understanding of the processes where valves are put in and is in a position to specify the proper valves required for each utility. We additionally assist prospects in fixing the issues of adverse installations and functions.
“To ensure optimum safety, effectivity and the extended service life of each system, the choice of the correct industrial slurry valve is critical. Valve selection relies on numerous elements, including the size and shape of particles, strain, temperatures and chemical content material.”
This AFS portfolio is especially well-suited for use in harsh conditions in various 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 functions, which rely on plant availability and the secure 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 suggests prospects can claim BEE procurement recognition of one hundred twenty five percent in opposition to all purchases.
