• Precise and consistent shot sizes
• Handles higher fluid pressure than most other valves
• Automatic suck-back after every dispense cycle
• Suitable for moisture-sensitive materials

The Spool Valve is based on a balanced spool design to create a fast "ON/OFF" fluid dispensing function that is not affected by material input pressure. The spool action displaces a portion of the material back into the nozzle during shut off. This creates an automatic "suck-back" anti-drip feature. An oil chamber is provided for use above the upper seal to create an additional liquid seal that will prevent moisture from being carried onto the spool. The design facilitates easy maintenance without the need for special tools. The valve is designed to be opened by air pressure and closed by a return spring (single acting). A port is provided so that the valve may be connected for air closing without the spring (double acting).

The TS5322 Mini Spool Valve is designed for higher accuracy with lower pressures. This valve option operates similar to the TS941 just in a smaller size.
