Direct-acting relief cartridges are normally closed, pressure-limiting valves used to protect hydraulic components    from pressure transients. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open to tank(port 2), throttling flow to limit the pressure rise. These valves are smooth and quiet, essentially zero leak,   dirt tolerant, immune to silting and are very fast.
