HUSH Trim

The HUSH trim is an innovative concept in control valve trim designed by Copes-Vulcan for high pressure drop liquid, gas, and steam applications.

HUSH is a cage guided trim that provides excellent control by directing the flow through a series of staged pressure drops. Cavitation, excessive leakage, hazardous noise, vibration and mechanical failures can be eliminated with HUSH trim – reducing down time and expensive maintenance costs.

Features:

• HUSH trim provides a cost effective option for severe duty applications where stacked disc trim is not required.

• Resolves existing problems for both compressible and noncompressible fluid flow applications.

• Pressure breakdown occurs in stages within the cage away from the plug surface, extending seat and trim life.

• Generally limits noise to 85dBa or less

• Multiple pressure drops prevent sonic velocity from occurring within valve

• Prevents aerated liquids from eroding trim and valve parts
