Italian thermoplastic valves manufacturer Formatura Iniezone Polimeri’s (FIP’s) flanged Dialock (DK) diaphragm valve, launched internationally in June last year, will be available to the South African market within the next few months through thermoplastic products supplier Astore Keymak.
The new flanged DK diaphragm valves will be supplied to the South African market, along with Astore Keymak’s valves partner, FIP, with whom the company has a longstanding relationship to “offer our customers a more superior, innovative and improved valve”, says Astore Keymak product manager Francois van Vuuren.
He notes that this new offering is part of the company’s strategy to continue evolving and innovating; this would ensure that it keeps its offering aligned to the changes in the valves industry and that it remains competitive in the market.
Van Vuuren says the new DK diaphragm valves have the advantage of optimised linearity and an improved characteristic curve; the hand wheel also allows for highly sensitive and precise adjustment during operation.
“The DK system on the diaphragm valves includes a hand wheel that is equipped with a patented, immediate and ergonomic locking device, which allows the wheel to be adjusted and locked into more than 300 positions.”
He says the design and components of the hand wheel make the operating mechanism waterproof, isolating all the internal metal parts from contact with external agents such as chemicals or acids.
In addition, he indicates that the valves have monolithic flanged, one-piece bodies and are suitable for shutting off and regulating aggressive chemical media. “The valves are also internally self-draining, which reduces chemical corrosion that is often a factor at processing plants.”
Van Vuuren explains that the valve body has an optimised internal fluid design that increases performance by up to 90%, compared with previous valve models, and is available in unplasticised polyvinyl chloride, chlorinated polyvinyl chloride, polypropylene homopolymer and polyvinylidene fluoride.
He says the valves are suitable for application in aggressive chemical environments where acids are used, such as processing plants, which require thermoplastic material products to withstand the damage.
FIP valves normally carry a one-year warranty, provided that the valves are installed by an approved fabricator and used in the correct applications, under the correct conditions and as prescribed by FIP.
Astore Keymak is the sole distributor of FIP’s industrial valves in South Africa.
