Hydraulic Symbol
Description
A screw-in, cartridge-style, remote sequence, pilot unloading valve, with optional fixed "unload/reload" pressure ratios for use in accumulator-type hydraulic systems.
Operation
In its steady state, the INUP10-30 blocks flow from port 2 to port 3. On attainment of a pre-determined pressure at port 1, the spool shifts to allow flow from port 2 to port 3. Since the spring chamber is vented at port 3, back pressure at port 3 will directly (1:1) affect the valve setting. If pressure at port 1 drops to a level below the ratio-established reload value, the valve will close, blocking flow from port 2 to port 3.
