SKF SGN-12-ZN Line Lubrication Doser Valve

SKF SGN-12-ZN Line Lubrication Doser Valve meters lubricant into SKF's dual-line lubrication networks, delivering controlled metering to lubricant lines in automatic systems. The ZN suffix identifies a zinc-coated steel construction within SKF's SG/SGA doser family, and the unit is designed for use with oil and fluid grease lubricants as part of dual-line (DuoFlex) configurations. In these systems, the doser works with a main feed line to supply precise lubricant pulses to downstream outlets, enabling repeatable dosing across multiple lubrication points while maintaining system pressure and minimizing bleed or backflow. The SGN-12-ZN variant inherits SKF's emphasis on robust sealing, reliable operation, and compatibility with standard SKF mounting rails and line components, supporting extended service intervals and easier maintenance in industrial machinery. Designed for integration into SKF Maxilube/DuoFlex architectures, this doser valve is a key component for centralized lubrication schemes where accurate metering and low maintenance are critical.
