IMI CCI
VLR Pressure Reducing Steam Service Control Valve
Reliable steam pressure reducing valve with noise and vibration reduction for severe conditions.
Reduces noise and vibration with multi-stage pressure control in severe conditions.
Ensures reliability with a thermally resistant body requiring no preheating.
Customisable configurations meet SIL, ASME, and ISO 9001 standards.
Features
The IMI CCI VLR Pressure Reducing Valve is engineered for precision steam pressure control under severe operating conditions, including high-pressure and vent-to-atmosphere applications. Designed to meet the needs of modern steam turbine systems, the valve reduces noise and vibrations through multi-stage pressure reduction. Its cage plug ensures a protected seat area and high rangeability. The valve’s durable, thermally resistant body requires no additional preheating beyond the demands of superheated steam, ensuring reliability and efficiency in high-demand environments. With customisable configurations for both high and low-pressure systems, the VLR complies with leading industry standards, including SIL, ASME, and ISO 9001.
