The 3-position shear valve aids quick mold change in injection molding applications.

Installed before the cooling water supply, the valve is used to shut off water supply and clear mold cooling water from the system between mold changes. An included check valve should be installed in the return line downstream from the Return manifold to prevent backflow to the mold.

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 molders who require additional protection from accidental valve movement.

Application:

The SWAP Valve is well-suited for cooling water Supply lines up to 2-inch NPT on frequently changed tools on small to medium tonnage injection molding 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, mold or manifold stand is acceptable.

Molder 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 Mold SWAP Valve.
• Water Shut-Off: Mold SWAP Valve 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.
