Description
An adjustable, direct-acting poppet cartridge valve designed to limit pressure in hydraulic circuits.
Operation
The DDRV-100 prevents flow from ➁ to ➀ until the set crack pressure at ➁ is achieved. The poppet then unseats allowing flow from ➁ to ➀ protecting the circuit from over pressurization.
Features and Benefits
- Rapid response to pressure surges.
- Low pressure rise.
- Hardened poppet and seat for long life.
- Hidden adjustment (tamper resistant).
- Aluminum knob and disc nut option.
- Adjustment may be locked in place.
- Industry common cavity.
