Relief pressure related to flow rate
A poppet-type, direct-acting hydraulic relief valve in the form of a screw-in cartridge intended for use
as a pressure limiting device for common hydraulic circuit protection. The spring acts on the poppet
and presses it onto the valve seat. If the hydraulic pressure is below the pre-set value, the valve is closed.
If the hydraulic force exceeds the pre-set value the valve opens and ow passes to the tank port until
the system pressure falls below the spring pre-set value and the valve closes again.
