CONFIGURATION
L Control Standard Screw Adjustment
Direct-acting relief cartridges are normally closed, pressure-limiting valves used to protect hydraulic components
C Adjustment 1000 - 6000 psi (70 - 420 bar), from pressure transients. When the pressure at the inlet (port 1) reaches the valve setting, the valve starts to open
Range 1000 psi (70 bar) Standard to tank (port 2), throttling flow to limit the pressure rise. These valves are smooth and quiet, essentially zero leak,
Setting dirt tolerant, immune to silting and are very fast.
N Seal Material Buna-N
