Diaphragm valve tank bottom

Compact stainless steel tank bottom valves for pharmaceutical production vessels.

The SED Tank Bottom Valve is designed for applications in the aseptic process industry offering a pocket-free interior surface, eliminating entrapment areas and minimizing flow resistance thus reducing the potential for process contamination. The SED tank bottom valve incorporates the same features and performanceof a standard 2-way diaphragm valve from the KMA and Steripure series 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 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 SED product range of customized solutions.

The SED tank bottom diaphragm valves with a casting body are unique and very affordable.
