The Nibco T-433-Y is a cast bronze silent check valve rated at Class 150, designed to prevent backflow quietly and reliably in a wide range of industrial and commercial piping systems. Featuring a PTFE (TFE) disc seat, this valve delivers excellent sealing performance and resistance to corrosion, making it well-suited for water, oil, and other compatible fluid applications.
With 1-1/2" Female Iron Pipe Thread (FIPT) connections on both ends, installation into standard threaded piping systems is straightforward. The silent check design minimizes water hammer and noise, extending the life of the overall system and reducing maintenance requirements.
