The TS5322 Mini Spool Valve utilizes a balanced spool design to deliver a rapid “ON/OFF” dispensing action that remains consistent regardless of material input pressure. During shut-off, the spool’s displacement pulls material back into the nozzle, creating an automatic “suck-back” effect that prevents dripping. To protect the system, an integrated oil chamber above the upper seal provides a secondary liquid barrier, preventing moisture from reaching the spool. This design is engineered for user-friendly maintenance, requiring no specialized tools for servicing.

Operating with the same functional logic as the larger TS941, the TS5322 is specifically optimized for applications requiring higher accuracy at lower operating pressures. It is primarily configured as a single-acting valve—opened by air pressure and closed by a return spring—but includes a dedicated port to facilitate double-acting operation for air-powered closing when required.
