These multi-way diaphragm valve blocks enable an almost infinite number of valve and process combinations. Multi-way valve systems achieve an extremely compact, space-saving design and represent an alternative to previous welded combinations, for example. Configurations can also be constructed that cannot be produced as welded combinations. The valve body is made of solid material and is available in all industry-standard materials and surface qualities. By using multi-way diaphragm valve blocks, the number of weld seams is reduced, the effort and documentation within the validation is minimised and ultimately compliance with the 2D rule or 3D rule is possible. Designs with the smallest dead spaces and the desired optimised draining are possible. All multi-way valve systems can be combined with the proven Bürkert actuator and automation concepts.
