Burkert has supplied a Robolux valve system on a machine that fills asthma inhaler cartridges for a pharmaceutical company.
Robolux's design has enabled the company to reduce the costs of the system by cutting the valve requirement from eight diaphragm valves down to four, according to Burkert.
Burkert has supplied a Robolux valve system on a machine that fills asthma inhaler cartridges for a multinational pharmaceutical company.
In addition, because the integrated design has only one block, there are fewer weld connections for the customer to make, reducing installation time and validation costs.
Because of the integrated design internal volumes are smaller, eliminating deadlegs and maximising sterility.
The design specification for the asthma inhaler project called for a valve system that would reduce the internal volume and the number of pipe connections on the filling and cleaning lines of the machine.
It projected a total of eight aseptic diaphragm vales per machine to carry out the control of the filling and cleaning lines.
Burkert's offering for the project used the company's type 2034 Robolux diaphragm valves mounted on a single customised stainless steel block.
In addition, Burkert also offered a type 5470 manifold block to pilot the valve block, providing a complete system solution from one supplier.
The modular nature of the 2034 Robolux design meant that Burkert was able to present its proposed design to the customer within two weeks.
As a result of its design of the Burkert Robolux double-weir valve system, and because the design has only one block, the number of valves required on the filling machine has been cut from eight to four, so there are fewer weld connections for the customer to make.
Moreover, the layout of the 2034 and the valve block means that internal volumes in the Burkert system are smaller.
As a result, medium losses are reduced, sterility is easier to ensure and maintain and the risk of cross-contamination is reduced.
Robolux valves are supplied with either manual or pneumatic actuators in sizes from 1/4in to 2in (DN4 -50).
They are manufactured with a choice of body types: 316-L stainless steel, ultra-pure polypropylene, polypropylene USP V1 and PVDF (polyvinyl-difluoride).
The valves also offer a wide range of diaphragm materials to suit all types of media, including EPDM, FKM, PFA/EPDM, PTFE, silicone and PFR91.
Robolux valves hold all major certifications: FDA, CE, USP V, USP VI, Atex, 3.1 and are applicable worldwide.
They are used in chromatography, but are also suitable for a wider range of applications including CIP/SIP processes, UF/MF filtration and filling and formulation.
