Description
The Armstrong International D25932 is a 1/2″ angle pattern TS-3 thermostatic radiator trap engineered for dependable performance in low- and medium-pressure steam heating systems. Built with a durable bronze body, this trap is rated for operating pressures up to 65 PSI, making it well-suited for a broad range of commercial and residential hydronic and steam applications.
Product Overview
Thermostatic radiator traps like the TS-3 series operate by sensing temperature differences between steam and condensate. When condensate and air are present, the trap opens to discharge them; when live steam arrives, the trap closes — preventing steam loss and maximizing system efficiency. The angle pattern design simplifies installation in tight piping configurations where straight-through flow is not practical.
