Description

The SMARTFLOW® SWAP® Valve is a simple, manually selectable device that supplies cooling water to the mould during processing or air to purge the water from the mould, cooling lines, Supply and Return manifolds prior to tool change.

For closed loop water systems we recommend you fit a TACO air separator valve.

The 3-position shear valve is a proven design. Ball detents, with approximately 15 pounds breakaway force, retain the valve selector handle in the selected position (WATER, PURGE or VENT).

An included check valve should be installed in the return line downstream from the Return manifold to prevent backflow to the mould.

Tubing may be connected to the manual vent-drain port so any residual water after the purge cycle can be drained into a suitable container or floor drain.

An optional spring-loaded, locking mechanism on the valve selector assembly is available for moulders who require additional protection from accidental valve movement.

Application:

The Mould Purge Valve is well-suited for cooling water Supply lines up to 2-inch BSP on frequently changed tools that are hung on small to medium tonnage injection moulding machines.

It is permissible to adapt 3/4, 1 1/4, 1 1/2 and 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, mould or manifold stand is acceptable.

Moulder Benefits

• Timesaving: Saves 15-20 minutes of unproductive tool change time by eliminating the tasks of draining multiple Supply and Return hoses plus cleaning-up water spills.
• Tool Condition: Protects tools from corrosion build-up during downtime and storage by evacuating water.
• Supply Line Permits fast identification of Supply lines by noting which manifold is connected to the Mould Purge Valve (MPV).
• Water Shut-Off: MPV shuts-off Supply water conveniently near the machine control, rather than with conventional ball valves on the water drops/risers or Supply manifold, typically located at the opposite side of the press.
• Full Port Design: Permits maximum cooling water flow at minimum pressure drop.
• Safety-Housekeeping: Eliminates root cause of accidents around the press by keeping personnel and floors dry.
• Optional Positive Lock: Eliminates accidental movement of valve selector handle.
