Hydraulic Symbol
Description
A screw-in, cartridge-style, pilot-operated (two-stage), spool-type hydraulic relief valve, intended for use as a pressure limiting device in demanding hydraulic circuits which require fast response and low hysteresis.
Operation
The INRV10-26 blocks flow from port 1 to port 2 until sufficient pressure is present at port 1 to force the piloting relief off its seat, allowing the main (second stage) spool to shift, opening port 1 to port 2. The cartridge offers smooth transition in response to load changes in demanding hydraulic circuits. Note: INRV10-26 cannot be used in crossover relief applications.
Technical Data
| Operating Pressure | 240 bar (3500 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 | T10-2B |
| Internal Leakage | 115 cc/minute (7 cu. in./minute) max. to 85% of nominal setting |
| Temperature | -40°C ~ 120°C |
Performance Curve
Flow performance should be reviewed together with pressure drop and working conditions.
