The Spray Valves are designed for precise spray applications of low viscosity materials. An external stroke control makes it easy for the operator to fine-tune fluid flow. Total control of the spray cycle is provided by adjustable fluid flow and precise control of prespray, atomizing air and post spray with the Multi-Purpose Digital Controller - TS500R. Maintenance is made simple by the elimination of troublesome spring loaded needle packings. Downtime is virtually eliminated with only one seal to replace during normal maintenance.
