The Smartflow SWAP Valve supplies cooling water to the mold during processing. Secondly, it supplies air to purge the water from the mold, cooling lines, supply and return manifolds prior to tool changes. It also provide a manual vent to release built-up air pressure within the cooling water loop after purging.

An included check vlve 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 drawing port so any residual water after the purge cycle can be drained into a container or drain.

An optional spring-loaded, locking pin is available for molder who require two hand operation. This prevents accidental valve handle movement.

Benefits

• Timesaving saves 15-20 minutes of unproductive tool change time.
• Supply Line ID permits fast identification of supply lines by noting which manifold is connected to the SWAP Valve.
• Water Shut-Off SWAP Valve shuts off supply water conveniently near the machine control
• Full Port Design permits maximum cooling water flow with minimum pressure drop.
• Safety Housekeeping eliminates root cause of accidents by keeping floors dry
• Mold Maintenance prepares injection mold for preventative maintenance and storage.
• Optional Positive Lock prevents accidental movement of valve handle

Application

The SWAP Valve is well-suited for cooling water supply lines up to 2 inches NPT. It is permissible to adapt 2/4″, 1-1/4″, and 1-1/2″ line sizes providing adequate cooling water flow can be achieved.

Typical mounting is on the press frame on the safety door frame. Mounting on any suitable surface, such as a platen, mold or manifold stand is acceptable.

For Normal Processing	Select WATER. Cooling Water is available to the supply manifold. Purge Air is blocked.
To Evacuate Cooling Water	Select PURGE. Purge Air is available to the Supply manifold. Cooling Water is blocked.
To Bleed-Off Trapped Pressure and Drain Residual Water	Select VENT. Press Manual Vent-Drain Valve. Purge air is blocked, cooling water is blocked.

Installation of an air separator in the return line of a closed loop cooling system is recommended.
