Steps to perform, when adopting B:
1. Plug the lower hose piece with a rubber plug (or a steel plug).
In case of a valve with mini clamp connections the closing of the
outlet may be obtained by using a tri clamp blind cap or by squeezing
an attached piece of tubing or by any other appropriate means.
2. Fill the valve chamber with the disinfectant through the upper hose
piece.
3. Leave to act for the prescribed time.
4. Empty the valve chamber by unplugging the lower hose piece while
holding a recipient under the valve allowing the disinfectant to flow
out.
5. Connect a flexible bottle with cleaned water to the upper hose piece
and rinse through the upper hose piece.
6. Leave the squeezed bottle connected to the upper hose piece and
clamp the hose to avoid contamination from air being sucked in
through the valve.
The valve is now ready to take a sample. The sampling must be performed immediately after disinfection
to avoid any contamination of the sample.
Flush with water after sampling. If the process media is sticky, viscous or aggressive or for any other
appropriate reason, do repeat the full CIP cycle after sampling.
WARNING
• Carefully follow the guidelines given for the chemicals involved
• Always remember to use safety goggles when steaming, CIPping, taking samples and all other
operations of the sampling valve
