Rotary Valves

  • Rotary Oscillating Valve
    supplier logo

    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
    supplier logo

    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.

  • Vacuum Rotary Valve
    supplier logo

    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.
