Description
An adjustable, bi-directional poppet type cartridge valve designed to limit pressure in hydraulic circuits.
Operation
The DBRVS-100 is comprised of two relief valves which prevent flow from ➀ to ➁ or ➁ to ➀ until the set crack pressure is achieved at either port ➀ or ➁. When the set crack pressure is reached, the poppet unseats allowing flow from ➀ to ➁ or 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).
- Industry common cavity.
