Cora Double Valve ®

Patent pending – Cora Double Valve

The Cora Double Valve is a dosing valve, composed of two intercepting elements. The butterfly is suitable to execute a rough dosing while the small rotor carries out a fine dosing. The maximum accuracy achievable is +/- 20 grams, the valve can be interfaced with dosing and weighing systems. The Cora Double Valve can be supplied with a sealing gasket between the vane and the dosing rotor (DVG). This solution allows the valve to work in applications with pressure up to 0,5 bar. The overall dimensions of the valve remain the same.

Rotor and Dosing Accuracy:

The dosing accuracy of the DOUBLE VALVE and VALVE GASKET is ± 50 grams with 90% of pharmaceutical products. CO.RA. has found a solution to obtain higher dosing accuracy to meet customer requirements. The solution consists of customizing the volume and number of pockets so it can reach a dosing accuracy of ± 10. In these cases, it is necessary to “fine tune” the process by running tests using the customer’s product. These tests can be carried out using either a DOUBLE or a DOUBLE VALVE GASKET that are available as CORA’s Technology Center.

Advantages:

• No lubricants Sterilizable in autoclave
• Minimum friction between butterfly valve and seal due reduced contact surface
