documentation requirements
A multiport valve consists of a valve body
machined from a solid block material with a minimum of three tube
ends. Multiport valves can be produced with up to 20 actuators and
40 tube ends or even more depending on the feasibility of multiport
valve manufacturing. The selection and specification of multiport
valves in the aseptic process industry becomes more and more
important. The reason is found in the advantages the product offers
in optimizing aseptic process purity and efficient product
manufacturing.
Innovative conceptual designs and modern machining capabilities are
integrated through the CAD-CAM system creating profitable individual
solutions with a high degree of flexibility. A prerequisite for this
is an operational structure which supports a close relationship
between sales, engineering and manufacturing. With a high vertical
range of manufacturing at its factory, SED is in an excellent
position to meet these challenging market needs. The continuous
innovative development of multiport block valve products is a main
focus of SED.
The ideal benefit for you, our customer, is achieved through active
and cooperative teamwork of both parties during the design and
specification of the valves. This refers especially to the process
requirements dictated by the P&ID’s for proper flow direction,
drainability and installation restraints. The application of
multiport block valves is mainly for the distribution, point of use,
sampling, diverting, mixing, bypass, drain and process sterilization
(SIP/CIP).
The below illustrations compare the hold up volume and the compact
design of a multiport block valve to a welded valve configuration:
The complete drainability is an important consideration for the design of multiport valves. The following illustration shows the correct and incorrect installation of a standard T-valve:
