TS941A Stainless Steel Spool Valve

Designed to dispense viscous materials fed from syringes, cartridges or pumps.  Two types are available, the TS941 (3/8" Inlet) and the TS941A (1/4" Inlet) for very high viscosity pastes, mastics and sealants.  The TS941 Spool Valve is based on a balanced 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. Various spool valve configurations provide adjustable anti-drip capabilities. 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.
