Included in the wide range of SÜDMO high quality hygienic valves are the Cross Contamination Proof butterfly valves.
These valves consist of two butterfly valves in series separated by a separately cleanable leakage chamber.
Double shut-off of the piping ensures absolute safety when separating incompatible liquids and the leakage chamber provides a means for detection of leaks.
This double safety is achieved at around two thirds of the cost of double seat, plug type valves.
The leakage butterfly valves, as with all SÜDMO valves, are constructed with FDA approved materials, streamlined low flow-resistance butterflies, optimum surface quality (Ra= 0.8 µm) and body design for maximum ease of cleaning.
Seal geometry includes expansion groove ensuring low wear extending seal life and alternate seal materials are available.
The leakage butterfly valve is available with pneumatic actuator and control top as an option for monitoring and control.
