About the Techcon TS941 Pneumatic High Pressure Spool Valve with Anti Drip Suck-Back Feature

The Techcon TS941 spool valve is perfect for highly accurate fluid or adhesive applications that require high pressure dispensing. The TS941 provides an anti-drop suck back feature and works best with medium and high viscosity materials. This valve is also well suited for moisture sensitive materials because of the chamber that prevents air from reaching the material.

The Techcon TS941 high pressure spool valve allows for fast, high pressure dispensing of many adhesive and fluid materials. This valve was designed to displace a small amount of fluid back into the nozzle during shut off (suck back) so there is no dripping after it stops dispensing. 

The design of the TS941 allows for easy maintenance without needing special tools and can be changed from single action (air on, spring close) to double action (air open, air close) to meet application needs. The TS941 can handle viscosities up to 3,000,000 cps at pressures of up to 2,500 psi.
