M-block stainless steel

GEMÜ multi-port valve blocks for sterile applications

M-block stainless steel

With its M-block technology, GEMÜ offers the most advanced solution for satisfying the stringent requirements of the pharmaceutical industry.

Conventional welded assemblies

Complex processes using welded assemblies are often still being implemented today, more than 20 years after the market launch of the first M-blocks. The valves, fittings and pipe components used for this require a lot of space, a greater installation and welding effort on site and lead to a correspondingly high validation expense. Not to mention a high hold-up volume and larger deadlegs in compliance with the conventional 6D or 3D rules.

GEMÜ solution for safe operation and high-quality products

Over the years, GEMÜ has implemented over 400 different designs and thousands of customized variants of multi-port valve blocks to make processes safer, increase system availability and reduce the life cycle costs of a system as part of a total cost of ownership (TCO) concept.

Consultation, engineering, manufacturing expertise

We begin supporting our customers as early as the planning phase by providing them with ideas and initial drafts. We then implement the design in the 3D CAD system and adjust it to closely meet the requirements of the particular customer. This jointly developed solution is then processed in our highly efficient machine shop. Several thousand blocks, with weights ranging from 0.1 kg to 500 kg, are processed each year on our multi-axis machining centres.

Conventional design                                                           8 welds /  4 welds

M-Block Design                                                                 No welds!

The hold-up volume is marked by red-coloured line sections.

  • Product advantages
  • Customer benefits of the GEMÜ M-block multi-port valve made of stainless steel:

Product advantages

  • Produced from a single block of material -> no internal welds, fewer fittings and fewer welds thanks to several valve seats in one unit
  • individually customized design
  • Integration of valves, measurement and control systems in a single unit; suitable for modular system designs
  • Certificate of compliance with the order, test certificate, inspection certificate 3.1, inspection certificate 3.2 available on request
  • Draining and deadleg optimized design (low hold-up volume, small wetted area, minimal dead spaces)
  • High-grade surface finish down to Ra 0.25 µm and EHEDG-certified diaphragm seal system
  • GEMÜ modular system with high-quality components (actuators, diaphragms, valve bodies, position indicators and positioner or process controllers) that are synchronized with each other

Customer benefits of the GEMÜ M-block multi-port valve made of stainless steel:

  • Simplified documentation and validation (e.g. less radiographic inspection)
  • Low space requirement
  • Optimization of production and operating procedures
  • Expertise and copy protection
  • Lower installation time, simplified commissioning and servicing
  • Reduced and/or simplified inventory (e.g. fittings)
  • Greater flexibility and lower costs during simultaneous implementation of a modular system design
  • Simplified validation and documentation
  • Increased product reliability
  • Increased operational safety
