DOUBLE VALVE and its use

DOUBLE VALVE and its use

The CO.RA. Double Valve is designed to satisfy the requirements of control, dosage, regulation and mixing in the process of Bulk filling.

It is composed of a Butterfly valve in the middle of which there is a rotor and is generally positioned under the discharge outlet of a process machine for example a Dryer or a Bin.

The valve is designed to be interfaced to an automatic programmable weighing system, the functioning is divided in two phases : during the first phase the butterfly opens, the underlying weighing system interfaced with the valve discharges 95 % of the set weight, it doses in a brief time the limit of the gross weight, during the second phase, the butterfly closes and automatically the central rotor  which allows the Drum/container to reach the required dosing limit corresponding to the Total weight of the product to dose with a precision of +/- 50 grams, is activated by means of pneumatic actuators 90 ° for the butterfly and 180° for the Rotor.

 

The valve is completely manufactured in AISI 316L, while the sealing gasket complies  with FDA norms. The rotor for the fine dosing can be customized with the number and volume of lobes according to the requirements of the customer.

The CO.RA. ® DOUBLE VALVE is available in the following diameters: 150 mm, 200 mm, 250 mm for the Butterfly, 80 mm and 100 mm for the rotor. The Valve bodies are satin finished and the rotor and butterfly are mirror polished. It is equipped with a control panel in AISI 316L/304 or in plastic material, and complete with variable interfaces according to the single requirements.
The most common application is the Drum dosing system, engineered by CO.RA. , which allows to discharge the product into a polyethylene liner (50 m long, and applied to the same structure) and to pack into Bags in a closed cycle controlling the weight with maximum precision.

The standard system is composed of an interface adaptor to the machine to serve, a CO.RA. ® DOUBLE VALVE, a liner fixing system complete with Vent filter, a dosing panel with display and keyboard incorporated and a weighing system with load cells.

The Double Valve is supplied with a sealing gasket between the Butterfly and the dosing rotor, or Double valve gasket ; this solution assures to have complete seal with the valve closed up to a value of 0,5 bar. The encumbrance dimensions of the valve remain unvaried.

Tablet Valve

Tablet Valve

CO.RA. has released a sterile valve for the interception of small and large tablets, capsules and silicone vial caps.
Its design confirms  the attention CO.RA. pays to operator needs during pharmaceutical and sterile working cycle, especially regarding the cleaning cycle.

The ergonomic components of the valve allow the operator to an easy assembling or disassembling.

The butterfly is AISI 316. The vane is in platinum cured silicone coated AISI 316L , the external surface is flexible and can have slits on both sides for the passage of large tablets or be without slits for the passage of small tablets. Thanks to this characteristic, the product flow can be interrupted without causing damage.

The silicone used is medical grade and is in compliance with the Pharmacopea 21 CFR 177.2600 norm.

 

 

The CO.RA. Tablet Valve offers three different versions: the “H” series with half-bodies in stainless steel AISI 316L and platinum cured silicone coated AISI 316L vane, the external surface is flexible; series “K” with plastic semi-bodies and platinum cured silicone coated AISI 316L vane, the external surface is flexible; series “E” is the economical version, light weight and made of AISI 316L tube with silicone coated vane.
The valve can be operated manually or with a pneumatic actuator.

CO.RA. product’s interchangeability allow the customer to choose two different type of the valve opening system: by handle or by pneumatic actuator in accordance with customer needs.
The CO.RA. Tablet Valve is essential in plants where a careful control of tablet flow is required and it finds its most suitable application on blister machines or on blister machine loading drums and bins.

SIL COMP ATEX

SIL COMP ATEX

ATEX is the conventional name of the directive 94/9/CE of the European Union for the regulations of equipment destined for to be used in areas that are risky to explosions.
From the moment that the law came into force, CO.RA has adapted all its equipment and handling solutions in such a way to satisfy all the requirements of the Directive to the Pharmaceutical and Chemical industries.
To satisfy this need, CO.RA. made a study for the application of its valves in the various classification zones, initially certifying them for applications in Zone 1/21. In 2007 it was decided to implement this certification for the employment in ATEX classified zone 1D/2GD by depositing a Technical Dossier with TYPE CE examination by the notifying board for all the types of valves manufactured.

The careful observation to the current norms in the installations where CO.RA. products are applied, favours the dynamic design of new systems intended to improve the quality of the service offered to its customers. 
For this reason, CO.RA. has decided not to limit itself only to the ATEX certification of the valves, but has continued to certify other products and systems belonging to its range of products, such as the Compensator available for Non classified areas and for ATEX zone 0/20 internally and externally.

The allignment of a pipeline with a machine and besides being used to recover misalignements of the elements to be connected, are necessary also for the connections of vibrating machines, avoiding the transmission of the same in the piping or in machines to be fed.
The compensators can be supplied with coupling flanges MF type or TC type, with measurements that vary from Ø 100 a Ø 250 for the coupling with MF type flanges while for the coupling with TC type flanges they vary from 1-1/2" TO 8".The silicone or PTFE used for the manufacturing of the Compensator is conform to the FDA norms.
Each raw material used for the manufacturing of the product is checked and selected, by qualified CO.RA. staff, to guarantee its customers the respect of the GMP norms. Furthermore to guarantee the traceability and quality of its moulded products such as Gaskets and Compensators, CO.RA. has invested in the construction of a white room expressly for the moulding.
