Hydrastore Pressure Reducing Valve - D-DFPRP

Operation

The D-DFPRP in its steady state, allows flow to pass from (2) to (3), with the spring chamber constantly drained at (1). When a pre-determined pressure is reached at (3), the spool shifts to restrict input flow at (2), thereby reducing (restricting) flow. If valve and pressure at port (3) exceeds setting, spool shift to open passage at port (1), thereby regulating pressure at port (3) by relieving excess flow. This valve is ideal for secondary reduced pressure control in common hydraulic circuits. The valve offers smooth transition in response to load changes.
