Direct-acting relief valve
SERIES1/  CAPACITY:95  L/min./  CAVITY:T-10A

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.
