    Double-V Dosing Valve

    The Co.Ra/Servolift double-v dosing valve system is a revolutionary product that replaces all other feeding technologies on the market today. The system can be set up for either loss-in-weight or gain-in-weight feeding, and can handle both powders and granules. The unit can dose directly out of a product container or hopper, and eliminates traditional feeder flaws such as residual product waste and product re-working (degradation and segregation).

    Can you currently disassemble, clean, and reassemble your dosing system in 15 minutes? If not, then the double-v dosing valve might be your solution.

    The double v dosing valve, paired with our controls can obtain a repeatable accuracy to +/- 10 grams.

    Rotary Oscillating Valve

    The rotary oscillating valve was invented almost 20 years ago by Co.Ra as a better solution to controlling the flow of powder. Unlike traditional rotary valves, the Co.Ra valve weighs only a few pounds and assembles without tools (if required).

    The valve oscillates back and forth using a 180 degree pneumatic actuator. The valve seals airtight at every degree position from 0 to 180 degrees. For applications that have very fragile products we can make the entire rotary disk in silicone (like our tablet valves).

    • Multiple disk designs for hard to friable tablets and variable pocket sizes,
    • Patented support system, wobble-free and robust,
    • 7 different body styles with over 30 standard actuation possibilities,
    • 316L, Hastellloy or FDA Delrin construction,
    • Certified high mirror finish, 0.02 µm,
    • Cleanroom produced, platinum cured silicon seals. Viton, EPDM and PTFE also standard.

    Rotary Tablet Valve

    The rotary oscillating valve was invented almost 20 years ago by Co.Ra as a better solution to controlling the flow of tablets or easily breakable materials. Unlike traditional rotary valves, the Co.Ra valve weighs only a few pounds and assembles without tools (if required).

    The valve oscillates back and forth using a 180 deg pneumatic actuator. The valve seals airtight at every position from 0 to 180 degrees.

    The special rotor is made in platinum cured (class VI) silicone and will not damage your tablets. The rotor also breaks down into separate parts for easy cleaning validation.

    • Multiple disk designs for hard to friable tablets and variable pocket sizes,
    • Patented support system, wobble-free and robust,
    • 7 different body styles with over 30 standard actuation possibilities, ;
    • 316L, Hastellloy or FDA Delrin construction,
    • Certified high mirror finish, 0.02 µm,
    • Cleanroom produced, platinum cured silicon seals. Viton, EPDM and PTFE also standard.

    Vacuum Rotary Valve

    The vacuum rotary valve (model VR8V) offers a special "super hygienic" design for metering of your products. We offer both pocket-by-pocket control or simple on-off. Unlike traditional vacuum rotary valves, the Co.Ra valve weighs only a few pounds and assembles without tools!

    Applications:

    • Constant feeding of any process equipment requiring a vacuum seal,
    • Metering of powders into mixing tanks,
    • Any application that needs a rotary valve with positive shut off.

    Butterfly Sole Valve

    Nearly 30 years ago Mr. Salvatore Lardieri, the owner of Co.Ra had a simple yet brilliant idea: A design for a very lightweight, ultra-clean butterfly valve that could be taken apart without tools. Before this moment all valves were heavy bolt together assemblies that could not be easily cleaned and inspected. Since this time Co.Ra has become the worldwide leader and innovator in sanitary valve designs and powder transfer technology.

    The butterfly sole valve has some key features that make it the valve of choice for the pharmaceutical and other clean industries:

    • Free floating disk design, no metal to metal contact,
    • Patented support system, wobble-free and robust,
    • 7 different body styles with over 30 standard actuation possibilities,
    • 316L, Hastellloy or FDA Delrin construction,
    • Certified high mirror finish, 0.02 µm,
