Working Principle
Fluid flows through the cage windows or around the plug periphery, with the plug position determining the effective flow area. The cage guides the plug and breaks up large vortices to minimize noise and cavitation. In multi-stage trims, pressure is reduced incrementally across successive stages to keep fluid above vapor pressure, preventing bubble collapse damage. Sealing surfaces mate precisely to achieve bubble-tight shutoff when closed.

Installation Requirements
Clean valve body thoroughly before installing trim.
Verify trim matches body size and pressure class.
Torque seat ring retainer to specification.
Ensure plug moves freely without binding.
Use new gaskets and O-rings during reassembly.
Perform hydrotest after installation to verify integrity.
