Description
The Trane DIA00002 0.50″ Diaphragm Weir Valve & Collar Stem Assembly controls and regulates fluid flow within system piping. It operates by using a flexible membrane that moves against a weir to open or restrict passage, allowing precise flow adjustment and sealing in HVAC systems during operation. Positioned within valve bodies, it connects with the stem and actuator components to respond to system demands. It maintains accurate flow control, reduces leakage, and supports consistent performance in heating and cooling applications.
