Description
An adjustable, direct-acting poppet cartridge valve designed to limit pressure in hydraulic circuits.
Operation
The ZRV-63 prevents flow from ➀ to ➁ until the set crack pressure at ➀ is achieved. The poppet then unseats allowing flow from ➀ to ➁ protecting the circuit from over pressurization.
Features and Benefits
- Rapid response to pressure surges.
- Hardened poppet and seat for long life.
- Compact size.
