Low leakage spherical poppet, all-steel zinc-plated body. Typical applications include Motor braking and cross-port relief, Port relief and pressure spike suppression, Mobile and industrial machinery. It is compatible with or cross-references Parker C10-2 cavity bodies (e.g. B10-8T steel), Screw-in cartridge manifolds, Hydraulic power units and mobile machinery. Equivalent / cross-reference designation: ISO 4406 18/16/13. Within industrial automation and process-control environments, components of this type are relied upon to keep critical equipment operating safely and efficiently. They are typically specified where uptime, repeatability and a predictable maintenance cycle matter more than upfront cost. A screw-in cartridge relief valve such as this one forms part of a larger machine or system, so correct identification and fitment directly affect the performance and safety of the whole installation. Parker parts are widely used across power generation, manufacturing, oil and gas, water and process industries, where engineering teams standardise on proven series to simplify spares planning. When selecting a replacement, confirm the exact model designation and verify that the mechanical and electrical interface matches the unit currently installed. Cross-checking the order code, mounting style and connection type against the existing device helps avoid compatibility issues and unplanned downtime during a maintenance window. Where several variants exist, the suffix often defines voltage, range or firmware, so it should be matched precisely rather than approximated.
