VDL Groep acquires Italian family company Olocco

VDL Groep has acquired the Italian company Olocco.
Olocco is a manufacturer of socalled rotary valves and industrial diverting valves.
With the company, located in Fossano (about 75 kilometres south of Turin), in its ranks, VDL expects to further strengthen its production and sales activities in the Foodtech domain, one of the ‘five worlds of VDL’.
VDL Industrial Products from Eindhoven, one of VDL’s operating companies, has been the exclusive representative in the Benelux of the products of industry partner Olocco since the early 1990s. Since then, Olocco has been selling the products of VDL Industrial Products in its home country Italy.
Like Olocco, VDL Industrial Products produces components for industrial installations for the handling and storage of dry materials (powders and granulates), such as rotary valves.
These valves dose dry materials from a storage system, like a silo, to a transport or other system or into a machine.
Diverting valves are, for example, built-in a pneumatic conveying or suction transport system through which dry materials are guided in a controlled manner to various machines or parts of industrial systems.

For the particular construction the several type of rotors and the minimum
tolerances, it ensures excellent airlock and good flowing of the product in pneumatic conveying lines.

In compliance with the provisions of the EC regulation nr. 1935/2004 concerning materials and objects intended to come into contact with food products
(MOCA), and to the EC regulation nr.2023 / 2006 on good manufacturing practices of materials and objects intended to come into contact with food.

UPH and UPH/sr


Quick disassembly

The “UPH” rotary valve type is particularly suitable for metering and pneumatically conveying of granular, flaky or ground products.

Thanks to its sturdy construction and flanging unified according to UNI PN10 standard (DIN 2576ND10) it is suitable for use in both heavy industry and in the chemical and plastic industrial fields.

The high quality of used materials, the parts in contact with the product in AISI316L stainless steel, the complete external bearings with PTFE gland packing and the good finishing make very easy the use of the rotary valve “UPH” in several markets; food and feed stuff industry, for example.

The “UPH-SR” rotary valve is the version equipped with a quick disassembly system with extraction bars, a completely removable rotor and internal surfaces polished and connected to meet the highest cleaning standards.
It is particularly suitable in those fields where the manufacturing processes require a frequent cleaning of the rotor and inside the body.
Thanks to the quick disassembly, time is saved and the time-work factor optimized.
