A look at the popular Smartflow Swap Valve system, with Molly Bryant of Smartflow.
The SWAP Valve is a simple, manually selectable device that supplies cooling water to the mold during processing or air to purge the water from the mold, cooling lines, Supply and Return manifolds prior to tool change.
The SWAP Valve is well-suited for cooling water Supply lines up to 2-inch NPT on frequently changed tools that are hung on small to medium tonnage injection molding machines. It is permissible to adapt 3/4, 1-1/4 and 1-1/2 inch line sizes providing adequate cooling water flow can be achieved. Typical mounting is on the press frame or the safety door frame. Mounting on any suitable surface, such as a platen, mold or manifold stand is acceptable.
