DESCRIPTION
An adjustable, direct-acting poppet cartridge valve designed to limit
p
ressure 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.
• Compact size.
