Core Functions

Reliable One-Way Flow Control
The Check Valves Hydraulic Cartridge Type allows hydraulic oil to flow in one direction while automatically blocking reverse flow. This helps maintain system pressure and prevents unwanted actuator movement.

High Pressure Performance
Designed for demanding hydraulic applications, the valve supports a maximum operating pressure of 350 bar, making it suitable for load holding and high-pressure hydraulic circuits.

Low Internal Leakage
The poppet sealing design minimizes internal leakage to a maximum of 3 drops per minute at 250 bar, helping improve load holding performance and hydraulic system efficiency.

Wide Operating Temperature Range
The hydraulic cartridge check valve operates in temperatures from -30°C to +120°C, making it suitable for both indoor and outdoor hydraulic equipment.

Reduced Contamination Risk
For stable operation and extended service life, hydraulic oil filtration of 20 μm or better is recommended to reduce wear and maintain sealing performance.

The performance data above are based on Model XCV-08B-20.
