The S&S® LG Series™ globe control valves are products with a high degree of process control versatility.
Whether the application calls for low-pressure general service or high-pressure severe service, this platform is fully scalable to meet the application and end user’s needs.
The product includes standard trim designs in linear, equal percentage, and quick opening characteristics along with basic cavitation and noise reduction trims.
For applications involving severe service fluid phenomena — including high noise, cavitation, or flashing — our advanced trim designs provide an additional level of protection and extended valve life. Options include the LG5 for noise abatement, LG6 for cavitation control, LG7 for flashing protection, and LG8 for cavitation elimination.
Broad Size and Trim Range – Sizes 1″–8″ with configurable trim packages, including noise abatement and cavitation control options
Flexible Shutoff Performance – ANSI/FCI Class II through Class VI shutoff capability to match control and isolation needs
Certified Low-Emissions Packing – ISO 15848-1:2015 certified packing performance (<50 PPMv over 100,000 cycles) for fugitive emissions compliance
Configurable Bonnet Designs – Standard, extended, and custom bonnet configurations to suit temperature, insulation, and accessibility requirements
Flow Characteristics – Linear, equal percentage, and quick-opening characteristics available to match process dynamics and improve controllability
