ABOUT ROIS ROIS is a brand owned by Uster. Founded in 1981, it is specialized on fine mechanics. Uster has always been cooperating with different companies which operate in the aeronautics, food, energy and valve industries. In 1996 Uster was ISO 9001 certified thanks to a careful organisation of the company processes. In 2000 the company moved into a new location and made big investments to buy up-todate machines in order to offer high precision and high quality manufactures. Uster is now able to launch the new micro-dosing valves thanks to it new brand ROIS.

Diaphragm Valve for food manufacturing and packaging The diaphragm ROIS valve dispenses exact and uniform quantities of food and beverages during the production as well as the packaging process. The diaphragm valve is suitable for: - Filling bottles, jars and bags with beverages or lotions. - Dispensing greases and lubricants on metal pieces used for canning processes. - Dispensing dots of cyanoacrylates and adhesives on packages. - Accurately dispensing micro beads and lines of solvents. Dispensed fluids: Beverages Creams Greases Adhesives Cyanoacrylates Sealants Diaphragm Valve for applications in the assembly industry Dispensed fluids: Greases Lubricants Adhesives Epoxies Silicones It is fundamental to reduce fluid waste during the dispensing in order to achieve productive efficiency. Diaphragm valve Rois is conceived to ensure greater control during fluid dispensing. The diaphragm valve is suitable for: Applications of greases on powertrain components and moving parts Distribution of solvents Oil dosing on sliding guides 3
Diaphragm Valve for cosmetic applications ROIS valve dispenses uniform quantities of cosmetic products, such as lotions, perfumes, cleanser and liquid depilatory wax. This valve ensures high standards of performance even for dosing of medium- to high-viscosity lotions as well as of medium-aggressive solutions. Dispensed fluids: Perfumes Lotions Sealants Adhesives Diaphragm Valve for electronic applications The high precision dosing ROIS valve dispenses precise and uniform quantities of product: it helps increase efficiency as well as productivity, and, at the same time, reduce the waste of material thanks to an accurate dispensing of silicones, adhesives and solder pastes during the assembly process.

Dispensed fluids: Glycerin Syrups Physiological Solution Saline Cyanoacrylates Diaphragm Valve for applications in the automotive industry It is fundamental to reduce fluid waste during the dispensing in order to achieve productive efficiency: Diaphragm valve Rois is conceived to ensure greater control during fluid distribution. The diaphragm valve is suitable for: Gaskets and electronic components gluing Lubrication of rolls, springs and pistons Application of greases on hinges and guides Dispensed fluids: Anaerobics Cyanoacrylates UV-glue Epoxy resins Greases 5
ROIS Diaphragm Valve Uster s diaphragm valve is developed for dosing of low- to medium-viscosity fluids, ensuring maximum precision. Thanks to its compact shape, this valve is easy and flexible to install in automated solutions Both utilisation and maintenance of the valve are easy: spare parts can be replaced directly by the user. Our valves are conceived to ensure millions of cycles before they need any maintenance. ROIS diaphragm valves cover a really wide range of applications: from precise microdosing in the microlitre range through to high-precision dispensing in hygiene requirements in the cosmetics or in the pharmaceutical. Our diaphragm valves can be used in an extremely wide range of industries, such as food, cosmetics, automotive, electronics, plastics, renewable energies, pharmaceuticals and biochemicals. 6
Diaphragm Valve Model VM100 The short valve travel ensures a maximum quick response and a positive shutoff. The valve is designed to handle high frequency cycling and disposes of a knob on the top to control the impulses. It is entirely built in stainless steel and the diaphragm is strictly made of PTFE/UHMW/PVDF so it is suitable for the most demanding industries.

The viscosity of a fluid Choosing the most suitable valve for a fluid, there are several several factors to be considered that influence the dosing:: one of the most important is viscosity. The viscosity can be defined ed as a physical quantity that measures the resistance of a fluid to flow along a surface. 10000-750000 100-90000 50000-70000 400-60000 80-10000 1500-1500 50-2000 250-500 150-200 1000 100 2-10 Cps 10000 2000-3000 100000 10000-25000 Viscosity in Centipoise 1000000 10 1 1 DISPENSABLE FLUIDS WITH W ROIS DIAPHRAGM VALVES: ALVES: Greases Lubricants Adhesives Epoxies Silicones Perfumes Lotions Sealants Adhesives Epoxy glue Cyanoacrylates Glycerin Syrups Physiological Solution Saline Anaerobics UV-glue Epoxy resins 11
