ROTARY VALVE

ROTARY VALVE

The Rotary Valve is a stellar valve, designed to resolve the problem of interception and flow control in pharmaceutical systems. 

The valve allows the continuous feeding of granules and powder without obstructing the flow while smoothly dosing the product into the process machines such as mills, tablet presses, capsule fillers, micro-dosers and sieves.
 
It was conceived and realized to enable the operator to clean it easily and quickly, without the use of any tools. Its use is optimized in sterile rooms.
 
By using the same tested production criteria used for the Sole Valve, the Rotary Valve is the CO.RA. product which allows the product to be smoothly dosed,

Thanks to its star shape and to its 180° reciprocating movement, it gathers the products and transfers it into the machine below while simultaneously blocking the flow from the upstream hopper thus avoiding product de-mixing. The speed and pause can be adjusted by means of a control panel interfaced to the valve, according to requirements.
The range of interchangeable half-bodies available allows the user to realize the application most suitable to his disassembly and cleaning requirements.

Product characteristics:
The standard version has an AISI 316L satin finish body, a mirror polished body is available upon request.
The rotor has six pockets but it is possible to customize the number and volume of the pockets according to the customer’s requirements. It performs a 180° clockwise and counterclockwise reciprocating rotary movement and it is possible to adjust the speed of rotation and the pause between one rotation and the other by means of a control panel.

Products advantages:
- Small face-to-face and light weight compared to traditional stellar valves
- Little friction due to reduced contact surface between rotor and gasket
- Sterilizable in autoclave
- Interchangeable with Sole Valve and Tablet Valve
- No need for lubricants

The applications:
The Rotary Valve is a bottom valve for powder containers and it is used where a steady and controlled flow is necessary.

A metal-to-metal Rotary Valve is available for applications where the product handled is particularly aggressive or not compatible with the material of the gasket. In this case the rotor is held in place by appropriate plastic supports which prevent the contact between the rotor and the valve body. The valve was conceived  to work in aggressive environments with no pressure and where there is no need for tight shut-off.

The cleaning and disassembly characteristics of this version are similar to the standard Rotary Valve.

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.
