This video demonstrates how to convert a gate valve that floats up in a 4963 body to a gate that pivots from the top and floats down. The process involves removing the lid, lifting the gate, and inserting a new piece with an O-ring. The video then shows how to install the floats and the top gate assembly, culminating in a normally open valve with a top gate.
