How to Order Deltrol DPOR2-100
Description

An adjustable, pilot-operated spool type cartridge valve designed to limit pressure in hydraulic circuits.

Operation

The DPOR2-100 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 or ➁ protecting the circuit from over pressurization.

Features and Benefits
  • Rapid response to pressure surges.
  • Low pressure rise.
  • Accurate pilot-operated design.
  • Hardened poppet and seat for long life.
  • Hidden adjustment (tamper resistant) option.
  • Aluminum knob and disc nut option.
  • Adjustment may be locked in place.
  • Industry common cavity.
