CO.RA. GEAR BOX

CO.RA. GEAR BOX

The Gear Box is a device that allows the manual opening of a butterfly valve as an alternative to the hand lever or to the pneumatic actuator.
This product is entirely made by CO.RA. from the design to production, in order to provide the pharmaceutical and chemical industries  a compact and lightweight product.
The Gear Box can be cleaned directly with jets of high-pressure water either manually or in automatic washing cabins.

This product can be installed on the Sole Valve if you want to partialize the butterfly opening in any position between 0 ° and 90 °, the handwheel is made of stainless steel and coated with FDA approved silicone.
The Gear Box has reduced overall dimensions compared to the lever or actuator. It also facilitates the opening and closing of the valve, especially valve’s with larger diameters, compared to the manual lever, as it needs less strength thanks to the reducer.

CO.RA. VR8V (Vacuum Rotary Valve)

CO.RA. VR8V (Vacuum Rotary Valve)

One of the aseptic Valves that CO.RA has designed for dosing and feeding the continuous flow powders and granules during the discharge is the VR8V®.
Manufactured according to GMP norms, collects the product and transfers it in the machine below by maintaining the product contained in the feeding tank above.
It is composed of a body and rotor entirely in AISI 316 L, complete with tests certificates and material roughness certificates (or on request approved FDA plastic material).
The Rotor is composed of 8 lobes, and has a variable speed according to the required applications, both in clockwise and anti-clockwise direction and enables to introduce a uniform and continuous  quantity of product between machine A and machine B, without blocking the flow of product and reaching a high precision. The diameters available on the market are  Ø 100 and Ø 150.
By using innovative technological solutions, the VR8V®  has characteristics which offer numerous competitive advantages respect to traditional Star valves :
-It always assures that it is closed regardless of the position of the Rotor;
-No lubricants are necessary
-It is sterilizable in autoclave.
Its full disassembly is immediate, obtained with the opening of the clamp that closes the two half bodies of
the valve. The decomposition of its elements is instantaneous. The parts that compose it can be subject to accurate cleaning and sanitation and re-assembled without any tool.

 

The VR8V®  is applicable wherever a continuous and controlled flow of product (powder, granules), particularly in the feeding of mills, tablet presses, capsule filling machines, microdosing and sieving machines.

It is also available in the VR8VG®  version provided with a sealing gasket between the half bodies that avoids a gap between the internal and external passage of the valve.

The Sealing Gasket is manufactured in the white room in the CO.RA production facility and is conform to the  FDA 21 CFR 177.2600 norms.
The flexibility in the technical solutions adopted by CO.RA offers the possibility to supply VR8V® with multiple control systems, to adapt to the different applications requested by the actioning systems of the various installations. Such systems compose the actioning of the motor by means of the electronic PLC interface or pneumatic control, brushless controlled motor, with or without encoder, with or without brake, complete with Stainless steel sump.
As per all the valves manufactured by CO.RA, also the VR8V®  is available in ATEX 94/09/CE.

SOLUTIONS AND ATEX CLASSIFICATION

SOLUTIONS AND ATEX CLASSIFICATION

Atex is the conventional name of 94/9/CE policy of European Union for regulation of equipment for Atez zone. The Policy became effective 1st March 1996 and became binding 1st July 2003 for all European countries and sets Atex certification for all products marketed in the European Union, apart from production place and laws in force, if installed in Atex environments. Since Atex policy came in force, CO.RA. attuned its own products to satisfy these requirements demanded by European Policy to chemical and pharmaceutical industries.

The firm R & D activity, process validation and all concerning the warranty of a complete service to offer its customers, employed CO.RA. staff in a specific research to manufacture “Made in Italy” Atex  gaskets for Sole Valve®, Rotary Valve®, Double Valve®.

 

With deposit of technical instalment at qualified authorities, CO.RA. uses special materials and compounds to produce eight different seal gaskets for its valves: Viton, Epdm, Si-Ptfe, Black Silicon, White and transparent platinum or peroxide catalyzed, coated-b, each one peculiar for different classifications of controlled environments in compliance with G.M.P. 

CO.RA. since beginning of its activities makes welding and polishing manufactures of its valves in the workshop with qualified technicians, so the company can keep continuous traceability of all materials used to manufacture valves and make test and deeper quality controls.

 

Besides to guarantee traceability and quality of its own gaskets as important element of the valves, CO.RA. decided to invest in a sterile room designed to manufacture eight different kinds of gaskets.

 

This allows placing of CO.RA. valves where safety for operator and protection of work environment are required.
