General Description

RV10-26X 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

Function and Features

The RV10-26X 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: this valve cannot be used in cross-over relief applications
The following features are given:

Adjustments cannot be backed out of the valve.
Adjustment options A, B and C: positive stops prevent springs from going solid.
Hardened spool and cage for long life.
Optional spring ranges to 207 bar (3000 psi).
Fast, smooth response to pressure surges.
Industry common cavity.

Details

The FR10-39 is a 2-way cartridge flow control valve. The valve has a 3/16" Hex Allen Head adjustment option with a cover cap. It comes as cartridge only with a NBR sealing.
