Hydraulic Symbol
Description
A screw-in, cartridge-style, direct-acting, poppet-type, hydraulic relief valve intended for use as a pressure limiting device for common hydraulic circuit protection.
Operation
The INRV10-20 blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to force the poppet from its seat. The cartridge offers fast response to load changes in typical hydraulic circuits requiring low internal leakage. Note: The INRV10-20 may be used in cross-over relief applications (back pressure on port 2) with the use of the "C" double back-up ring seal option. See Ordering Table.
Technical Data
| Operating Pressure | 228 bar (3300 psi) |
|---|---|
| Flow | The Performance Chart illustrates flow handling capacity at maximum setting for each spring range option. Pressure rise will vary with spring range and with setting within range due to flow forces. Consult factory for specific flow characteristic values. |
| Cavity | T08-2A |
| Internal Leakage | 0.25 cc/minute (5 drops/minute) max. to 80% of nominal setting |
| Temperature | -40°C ~ 120°C |
Performance Curve
Flow performance should be reviewed together with pressure drop and working conditions.
