Manual Tank Bottom Valve
Tank Bottom Valve
The Tank Bottom Diaphragm Valve is designed for use at the bottom
of a tank or vessel to drain or sample while minimizing the
interior sump and preventing any dead leg for bacteria or

Manual Tank Bottom Valve
The Tank Bottom Valve is a single seat valve, assembled at the
bottom of tank to be used in diary, food processing, beverage,
pharmaceutical and fine chemical industries.
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 our product range of customized
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.
Please contact us for these options.
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 butt weld tube end standards (see fold-out page
13), aseptic clamp, screw connection (see page 14 and 15) or other
special ends. The size range available is the same as the two-way
Tank bottom valve is used to vent the container material and the
material will not be stuck in the valve chamber. The design of the
seat opens to the inside of the container avoiding the overvoltage
because the pipe leads to the possibility of accidental opening of
the valve. The tank bottom valve has two designs in 45° and 90°,
pneumatic manual interchangeable.
