1. Open the valve slowly and take the sample.
NB! In order to ush the valve seat before sampling you may choose
to let the rst few seconds of ow go to drain.
2. Close the valve aer the sample has been taken.
3. Clean the valve by ushing with steam, water or hot water.
If the process media is sticky, viscous or aggressive or for any other appropriate reason, do repeat a full
CIP cycle aer sampling in case steam is not available and ushing with water prove insuicient.
WARNING
• When sampling at a high pressure and/or with a low viscosity process media it may ow rapidly
into the sample recipient. Therefore open the valve slowly. Special care must be taken with
pneumatically operated valves, as they open abruptly. If problematic, consider adjustable
actuators.
• Always remember to wear safety goggles when steaming, CIPping, taking samples or any other
operations of the sampling valve
