  • Direct-acting relief cartridges are normally closed, pressure-limiting valves used to protect hydraulic components from pressure transients. When the pressure at the port 1 (inlet) reaches the valve setting, the valve starts to open to port 2 (tank), 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. Valve is relatively insensitive to varying oil temperatures and oil borne contamination. Suitable for use in load holding and cross port relief circuits applications.
