Crevice-free valves aid CIP and SIP

The elimination of traps and crevices which might increase the potential for bacteria growth is an important design requirement for control valves used in food processing.

Control valves which have smooth, cavity-free internals help to promote effective clean-in-place (CIP) or sterilised-in-place (SIP) operations.

Samson Controls offers a range of valves which incorporate these features. For example, the 3347 control valve has polished steel parts to ensure the highest purity for the process medium, special polytetrafluoroethylene (PTFE) bushing, and an additional steam line connection to prevent bacteria from spreading at the actuator stem guide.

Samson's 3249 valve is equipped with an ethylene propylene diene monomer diaphragm and a back-up safety packing box to ensure total protection against bacteria spreading and to prevent product leakage.

Applications which involve pasty, fibrous, or highly-viscous products can be controlled by Samson's type 3345 cavity-free valve body.

This features a diaphragm made of either rubber, nitrile, butyl or PTFE that acts both as a seal and a valve plug.
