Description
A fixed bypass-type cartridge valve designed to regulate priority flow while bypassing excess flow regardless of load pressure.
Operation
The DFR-100-3 maintains a constant flow within specified accuracies from ➀ to ➂ regardless of downstream load pressure at ➂ or bypass leg ➁. When flow produces a minimum predetermined pressure differential across the compensator spool control orifice, the spool shifts against the spring force to throttle the flow and maintain the priority flow setting. Reverse flow is not regulated.
Features and Benefits
- Pressure-compensated.
- Quiet response.
- Bypass port ➁ may be fully pressurized.
- Industry common cavity.
