SYMBOL
DESCRIPTION
Direct-acting relief cartridges are normally closed, pressure-limiting valves used to protect hydraulic components from pressure transients.
OPERATION
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.
FEATURES
* Will accept maximum pressure at port 2
* Suitable for use in cross port relief circuits.
* The seals on the adjust screw are exposed to system pressure which means this valve can only be adjusted when the pressure is removed.
* Valve is relatively insensitive to varying oil temperatures and oil borne contamination.
* Suitable for use in load holding applications
