Crevice-free valves provide aseptic control

Samson Controls offers a range of valves that incorporate smooth, cavity-free internals and help to promote effective CIP and SIP (Clean or Sterilised in Place), while also aiding self draining.

Eliminating areas that might increase the potential for bacteria growth such as traps and crevices is an important design requirement for control valves used in aseptic applications.

Samson control valves are manufactured to quality assurance systems certified to ISO 9001 and meet stringent FDA requirements.

For example, its type 3347 control valve has polished steel parts to ensure the highest purity for the process medium and special PTFE bushing.

An additional steam line connection is used to meet stringent purity requirements preventing bacteria from spreading at the actuator stem guide.

The type 3249 valve is equipped with an EPDM diaphragm and a back-up safety packing box to ensure total protection against bacteria spreading and to prevent product leakage.

These sealing systems, which constitute the main components of the valve construction, have been designed to ensure a long and reliable service life.

Process applications that involve pasty, fibrous or highly viscous products can be controlled using Samson's type 3345 cavity-free valve body, which features a diaphragm made of either rubber, nitrile, butyl or PTFE that acts both as a seal and a valve plug.

These valves are available with various connections including hygienic couplings, flanges and clamp connections according to ISO 2852 and welding ends.
