ChargePoint Technology sell "WIP Passive / Drain"

The specifically designed Wash In Place (WIP) Passive device ensures thorough washing of a ChargePoint Active valve's product-contact sealing areas. The WIP Passive/Drain mimics a standard Passive unit, locking into the Active to let it open within a contained environment before the wash cycle runs. An O-ring around its outer perimeter creates a liquid seal against the Active unit, and some designs are also pressure-rated to handle recirculation, flood, or high-pressure washing cycles.
