Build a product and CIP route matrix before choosing valves. Every recipe, tank, filler, return path and blocked condition should have a defined state.

Review pipe slope, low points, equipment nozzles, valve orientation and trapped volumes. A polished pipe can still retain product or chemicals.

Use the verified hygiene risk to decide single-seat, mixproof, double-block or physical-disconnection boundaries. Document leakage handling and detection.

Define position indication, air failure state, permissives and mismatch alarms for critical product, CIP and drain paths.

Require hygienic fittings, weld procedures, purge control, inspection, cleaning and traceable repair records appropriate to the agreed scope.

Reserve clearly capped, drainable and documented connections rather than leaving uncontrolled branches that can become stagnant zones.
