Description
The CR08-28H is a screw in, cartridge style, direct acting, differential area, poppet type, internally vented, bidirectional hydraulic relief valve intended for use as a pressure limiting device for common hydraulic circuit protection
Operation
The CR08-28H blocks flow from either port 1 or port 2. On attainment of a predetermined pressure at either port 1 or port 2, the spring-opposed poppet is forced from its seat. The cartridge offers fast response to load changes in typical hydraulic circuits requiring low hysteresis, low pressure rise and low internal leakage
Features
- Factory preset hidden adjustment.
- Pressure setting range of 138-276 bar (2000-4000 psi)
- Corrosion-protection of 960 hours salt spray per ASTM B117.
- Hardened parts for long life.
- Industry common cavity.
