ChargePoint Technology sell "WIP Lance"

The specifically designed Wash In Place (WIP) Lance device ensures thorough washing of a ChargePoint Active valve's product-contact and sealing areas, the process connection nozzle, and even the process vessel itself. The WIP Lance assembly connects to a standard Passive unit, allowing the Active to open and the wash cycle to run in a contained environment. The sprayball and lance sit inside flexible PTFE bellows, connected to a Passive unit at one end and a traversing platform at the other that moves the assembly up and down. As the lance passes through the open valve, it washes the valve and disc faces and continues through the nozzle connection into the process vessel.
