Dynamic Fluid Control (DFC) has bought RF Technologies, a USA-based pinch valve manufacturer with an established global presence. The purchase, which includes RF Technologies’s wholly owned Finnish subsidiary, follows DFC’s acquisition in mid-2008 of local company Insamcor.

It extends the product line of Benoni-based DFC to include the AiRFlex and RF valve brands, which are used in applications involving abrasive, corrosive, scaling and plugging slurries and powders.

Commenting on the acquisition, DFC group managing director Henry Smith says that it would satisfy demand in the South African mining sector for a high quality pinch valve.

“Strategically, the RF Technologies footprint in North America, South America and Europe will accelerate our penetration of the international market for minerals processing valves,” Smith says.

“Locally, we will now be able to offer South African customers the most comprehensive range of high quality branded slurry valves available anywhere.”

The AiRFlex and RF valve ranges comprise pinch valves sized from 25 mm to 1,500 mm in both manual and automated configurations.

While AiRFlex valves handle line pressures up to four bar, RF valves are designed to control slurries in the pH range 1 to 13 at pressures of up to 40 bar and temperatures up to 12OC. Actuation can be manual, pneumatic, hydraulic or electric.
