Diaphragm Valves
Tank Bottom Valves
The tank bottom valve is designed for applications in the aseptic process industry offering a pocket-free interior surface,
minimized sump, eliminating entrapment areas and minimizing flow resistance thus reducing the potential for process
contamination. The tank bottom valve incorporates the same features and performance of a standard diaphragm valve utilizing
the same valve components for a flush mounted tank bottom valve or side mounted tank and sample valve.
The tank valve body is machined as standard from solid bar stock material 1.4435/316L ASME BPE and other alloy materials are
available according to the specification. The standard design offers one valve port outlet. There are a number of different options
available for sampling, sterilization and multi-outlet configurations that are standard in the product range of customized solutions.
It is preferred to weld in the tank valve directly in the vessel. Mounting the valve directly to the tank minimizes the hold up
volume, the most important criteria for this application. If removal of the tank valve from the tank is required, versions are offered
with flange or clamp connections.
Tank bottom valves are typically used for tank discharge, draining, sampling, cleaning and/or sterilizing, rinsing and isolation of
down stream processing.
The outlet port of the tank valve is available with all weld tube end standards, aseptic clamp (see page 57) or other special ends.
The size range available is the same as the two-way valve.
