Weir Valve Alternative

Aseptic Shut-off Valves – Rattiinox Disk Aseptic Valve DAV

Category: Tag: Brand:

Aseptic Shut-off Valves for SAFE areas is a patented valve body design which eliminates the most common issues found with poor performing hygienic weir valves.  The diverting valves are designed for fluid or gas deviation common to filtration and CIP skids and many other process streams.
The body shape and their internal design offer a very reliable component for Aseptic Processing Application.  Standard version are short butt weld ends but, on demand, may be delivered for orbital welding or with Tri-Clamp connections.  Available on several configurations to fulfill customer needs on all applications: 90° and 180° design, for vertical installations with coaxial outlets or for horizontal installations with tangential outlets reaching a full drain-ability. The valve body is precision machined from solid 1.4435-BN2 compound for superior corrosion resistance.  The valve is standard with a PTFE seal (FDA).  Laser marking is standard to comply with traceability and validation requirements.  Material 3.1 certificates according to FDA or USP and internal surface finishing check is standard.  More than 30 years of experience in the stainless steel machining has made of Rattiinox a successful firm in the supplying of components for pharmaceutical, chemical and alimentary installations.  Modern management of Rattiinox is orientated towards delivering services and products able to satisfy Customers requirements as concern aseptic processes and high purity technologies by designing with dedicated equipment, devices and systems.  Rattiinox aims to satisfy the customer by providing a mix of products and services geared towards high quality production, in full respect of the aseptic systems and regulations.  Our services will range from the simple consulting, also in the field, for a better understanding of the real needs, to the delivery of standard and dedicated process components, up to be completed by process engineering.  All this is guaranteed by the collaboration of Rattiinox with a team of experts with extensive experience providing process engineering, components and systems.

 

Since 1970 Rattiinox has been developing and manufacturing innovative stainless steel valves and components for the pharmaceutical, biotechnology and food and beverage industries. Rattiinox is focused on aseptic processing equipment.
Characteristics: Valve body machined from solid compound. Double metal closure, no gaskets between the body and the rod valve guide.
The state of the art of the CNC machining technologies, such as 5 axis machining centers equiped with more than 100 tools, 8 axis multitasking lathes, special ultrasonic cleaning machines and much more… Only the latest generation CNC machine tools are used to get high quality standards like 0,4Ra surface finishing directly on the machine tool working. R&D and engineering of new product and special assembly are available using 3D CAD and CAM soft ware.

Clean and Aseptic Valves of DAV Product Line have simple and safe design, with their full drain-ability, without asymptotic seal and dead leg, are offering fast cleanability and sterilization practices. They are designed to fulfill stringent demands of CIP-SIP and Production Cycles on Aseptic Processing.

Sterile access divert valves are used in a wide range of applications were a purge line is required. Unique to the Rattiinox divert valve is the ability this application can be accomplished without the associated dead-legs found in hygienic weir valves. The sterile access CAD divert valve from Rattiinox does not have dead-legs or unused portions and is suitable for a wide range of critical applications in the pharmaceutical and biotechnology industries.
