Air Operated TS941 Spool Valve
TS941 TS5322 Spool Valves Adhesive Dispensing

The TS941 series high pressure air operated spool valves are suited to making controlled deposits of many medium to high viscosity gels and pastes. The valve body is made from stainless steel for low maintenance handling of thick materials such as RTVs, silicones, sealants and grease. A piston moves back against the flow to shut-off and prevent material oozing.


Designed to dispense viscous materials fed from cartridges or pumps.  The TS941 Spool Valve is a spool design for a fast ON/OFF dispensing action unaffected by material input pressure, and is ideal for material with a viscosity between 5000 to 3,000,000 CPS at pressures of up to 2,500 psi. The hardened spool slides in Teflon seals and displaces a portion of the material back into the nozzle during shut off, creating an accurate “suck-back”anti-drip action. An oil chamber creates an additional liquid seal that prevents inadvertent moisture from entering the spool mechanism. The valve design facilitates easy maintenance without the need for special tools. The valve is opened by applying air pressure and closed via a return spring (single acting). A port is provided so that the valve may be connected for air closing without the spring (double acting). All side ports can be rotated in 120 or 90-degree increments to accommodate multiple valve connections.

Recommended digital timed controllers for these valves are the TS250, TS350 and TS500R. Typical applications for this valve include edge sealing using silicones and sealants, filling and packaging, automated paste dosing.

Adhesive Dispensing Ltd provide a wide range of equipment options for dispensing almost all assembly fluids - from watery liquids, solvents, primers and activators through to thick pastes, sealants, silicones, gels and epoxies.

Products are shipped in the UK by courier on a tracked & insured service. Europe deliveries, items are shipped via DPD or DHL. For all international shipments, items are sent DHL or via FedEx.

  Maintenance of this product

This valve is designed for use with most medium to high viscosity materialsIn order to ensure adhesive does not cure at the tip end, we recommended the use of a tip cap (7015LLBPK) when the valve is not in use. It is advisable to hold stock.

  Common Applications

Spool valves are used for many varied assembly and production processes where controlled deposits of medium to high viscosity materials need to be applied. Some common applications include:-

Dots and beads of Gels  
Dots and beads of Mastics
Dots and beads of RTVs
Dots and beads of Silicones
Deposits of Grease
Dots and beads of Pastes
General adhesive application
  Use this stainless steel elbow fitting with 3/8" NPT thread for high pressure connection of fluid lines.
