• The valve is designed to be used in applications where
fine pressure compensation is not required and an
economical solution is important (2)
• One piece cartridge housing ensures internal

• Factory-adjusted low variation option (Model “L”) is
available for applications where low variation of flow from
valve to valve is essential at a given current or when an
external pressure compensator is used.
