TAH has designed and manufactured innovative dispense valves specifically for two-component urethanes. These materials are moisture sensitive so any contact with air can cure the material and lock up dispense valve. The Series 400XT and 450XT SnuffBack Valves use a production-proven design that eliminates exposure of wetted shafts to air. Features include:
Thicker tie plate increases the distance between the lip seals, extends seal life with less down time
Divorcing block separates the air cylinder from the rest of the valve
Same manifold and ergonomic handle as our standard 400/450 valves
