Smooth, Crevice- Free Valves For Aseptic Applications

3347 control valve

Eliminating areas in process systems which may increase the potential for bacteria growth, such as traps and crevices, is an important requirement for control valves used in aseptic applications.  Control valve specialists SAMSON CONTROLS offer a range of products incorporating these features which are manufactured to quality assurance systems certified to ISO 9001, whilst also meeting stringent FDA requirements.

For example, their type 3347 control valve has polished steel parts to ensure the highest purity for the process medium, special PTFE bushing along with an additional steam line connection that is used to meet very stringent purity requirements preventing bacteria from spreading at the actuator stem guide.

Another example is the Type 3249 valve which is equipped with an EPDM diaphragm and a back-up safety packing box to ensure total protection against bacteria spreading and prevent product leakage.  These sealing systems, which constitute the main components of the valve construction, have been thoroughly developed and designed to ensure a long and reliable service life.

Process applications which involve pasty, fibrous or highly viscous products are best controlled by Samson’s Type 3345 cavity-free valve body which features a diaphragm available in either rubber, nitrile, butyl or PTFE which acts both as a seal and a valve plug.

These valves can be easily installed into the process line as they are available with various connections including hygienic couplings, flanges and clamp
connections according to ISO 2852 and welding ends.
