How to Order
Description
An adjustable, pilot-operated spool cartridge valve designed to limit flow in hydraulic circuits.
Operation
The DPOR-100 prevents flow from ➀ to ➁ until pressure at ➀ exceeds the set crack pressure and opens the pilot section. The pilot flow creates a pressure differential across the spool which causes the valve to open allowing flow from ➀ to ➁ and thus protecting the circuit from over pressurization.
Features and Benefits
- Rapid response to pressure surges.
- Quiet operation.
- Low pressure rise.
- High accuracy of pilot operated design.
- Hardened parts for long life.
- Adjustment may be locked in place.
- Hidden adjustment (tamper resistant) option.
- Adjustment prevents spring from going solid.
- Industry common cavity.
- High flow capacity.
