SED – Tank Bottom Diaphragm valve Customized designs

Compact stainless steel tank bottom valves


  • The tank valve body is machined as standard from solid bar stock material 1.4435/316L
  • The standard design offers one valve port outlet
  • Minimized dead leg and internal sump
  • Suitable for mounting with SED Steripur and KMA series Actuated

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

The datasheet (see below) shows some examples of standard and customized designs of tank diaphragm valves.
