Spool Valves
TS941 Spool Valve

The Spool Valve is based on a balanced spool design to create a fast "ON/OFF" fluiTS941 Gasketingd 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 aTS5322 Spool Valvend 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 TS941 Series side ports can be rotated in to conveniently locate valve connections. The hardened spool slides in high quality seals and is suitable for use with materials having a viscosity of up to 3,000,000 cps at pressures of up to 2,500psi (172bar). Output is ¼ NPT allowing multiple tip termination.

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.

Recommended Controller: TS500R, TS350, TS250
