The TSO Twin Shut-Off Assembly control valve assures instant, positive, and simultaneous opening and closing of the base and catalyst valves when using twin lines. The valves are ideal for filling joints in pavement, anchoring, and placing pavement markers. The two components, base and catalyst, do not join together until they meet in an inexpensive, disposable mixer.
TSO components are Delrin, aluminum, and stainless steel. Combined with the RTA, Remote Trigger Assembly, the valve is remotely operated from the end of the dispense hose by actuating one of two manual buttons.
