Armstrong International TVS813 1" Steam Trap Valve Station

Armstrong TVS813 1" Steam Trap Valve Station is a cast-iron, horizontal-installation trap station in Armstrong’s TVS 800 series that combines an inverted bucket steam trap with integral isolation valves and a built-in stainless-steel screen strainer. It features 1" NPT inlet and outlet connections, a blowdown valve for strainer cleaning, and internal check valves, and it is designed for steam systems up to 80 psi. The TVS813 can retrofit existing Armstrong cast-iron traps with identical face-to-face dimensions, enabling straightforward upgrades. It also offers trap-monitoring options via probe connections and, when ordered with the thermic vent bucket option, provides a bimetal-controlled auxiliary air vent for rapid venting at start-up, along with continuous air venting to improve startup efficiency.
