Description
SANITARY VALVE FOR DOSAGE OF GRANULES AND POWDERS – CO.RA. VR8V
The VR8V valve is an aseptic valve, designed and manufactured to dose powder and granules in pressure and vacuum service . The VR8V valve allows a continuous flow of powder and granules, thus obtaining extremely uniform dosing during the feeding of mills, press machines, filling machines, micro-dosing machines and screening machines. The CO.RA. The VR8V valve has a spherical design that allows to intercept the loading system with the product discharge line.
Technical characteristics
SANITARY VALVE FOR DOSAGE OF GRANULES AND POWDERS – CO.RA. VR8V
General:
- Half bodies in AISI 316L (DIN 1.4404) satin finish (mirror polished on request)
- Rotor in AISI 316L (DIN 1.4404) mirror polished
- Rotor with 8 pockets with variable speed to dose a controlled quantity of product
- NO O-ring on the shaft
- Lightweight and compact design: Easy to disassemble, inspect and clean
- Materials: stainless steel and elastomers (FDA approved, certified upon request)
- Manufactured according to G.M.P.
- Allows continuous feeding of granules and powders without obstructing the flow
- Traceability over time (batch number)
- Compact and lightweight compared to conventional rotary valves
- The valve always prevents dust leakage regardless of the rotor position
Maximum precision rotor:
The precision of the VR8V and VR8VG dosage can reach ± 5 grams with 90% of pharmaceutical products, to achieve this result CO.RA. continuously improves and develops its products and has developed the valve rotor in order to improve the dosing precision of the DN 80 and DN 100, while for the DN 150 the flow rate of the rotor has been increased in order of providing dosing of significant amounts of product in a short period of time. These high precision results can be achieved with the rotors mentioned above, but only if used with a motor and weighing and control system supplied by CO.RA. CO.RA. has studied a solution to achieve an even higher dosing precision which involves customizing the volume and number of cavities of the valve rotor that allow you to achieve a precision of dosage of ± 2 – 3 grams . In these cases, the valve requires fine tuning . based on dosing tests performed with the customer’s product. These tests can be performed with the VR8V and VR8VG available at our Technology Center . The possibility of customizing the rotor both in volume and number of cavities ensures great flexibility in performance , allowing optimization of the process at any time simply by replacing the rotor.
Advantages:
- Without lubricants
- Sterilizable in autoclave
Applications:
The SOLE VALVE can be used in the pharmaceutical, chemical, food, cosmetic and omeopathic industries . The attention paid by CO.RA.® for the cleaning, sterilization, interchangeability and maintenance of the equipment and components used has always guaranteed the best quality of its products.
