Description
Overview
The MOP/MOP-F baffle plate is a passive inline device installed downstream of steam control valves to reduce outlet velocity and suppress noise and vibration. Intended for turbine bypass, vent and other high-velocity steam applications, the design limits sonic flow in accordance with IEC 60534-8-3. Installing a baffle plate instead of upsizing the valve allows more compact and cost-effective valve system layouts. Available in straight-through body form with corn-type (MOP) or flat-type (MOP-F) plates, compatible with standard BWE end connections. IMI has applied this solution in steam systems since 1980.

Key features
Product form and function
The unit is a cylindrical metallic assembly containing an internal perforated plate. When fitted downstream of a control valve it reduces outlet velocity and interrupts acoustic paths to suppress noise and vibration in high-pressure steam systems. Designed for industrial environments with standard BWE connection compatibility. IMI offers engineering support for selection and integration.
