Description
The HydraForce RV50-26 is 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.
The RV50-26X 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.
Note that this valve cannot be used in cross-over relief applications.
- Adjustments cannot be backed out of the valve.
- Adjustments prohibit springs from going solid.
- Hardened spool and cage for long life.
- Rapid, smooth response to pressure changes.
- Industry-common size.

- Burst pressure: 1037.7 bar (15050 psi)
- Relief pressure defined: pressure evident at
- Pressure evident at 7.57 litres / minute (2 gallons / minute)
- Reseat pressure: nominal 90% of crack
- Relief pressure range: 20.7 to 344.7 bar (300 to 5000 psi)
Flow rating: 113.6 litres / minute (30 gpm) at maximum pressure
This valve can be used with mineral based or synthetic hydraulic fluid with lubricating properties
