• Specifiion

• Key functions

1.Hydraulic Pressure Regulation: In relief valves, it sets the system’s maximum safe pressure, preventing damage to pumps, hoses, and cylinders from overpressure (a leading cause of hydraulic system failure).

2.Valve Spool Positioning: In main control valves, it provides a "return force" to reset valve spools to their neutral position when the operator releases the control lever. This stops unintended movement of the boom, arm, or bucket.

3.Force Consistency: Its stable spring rate ensures the hydraulic system maintains consistent pressure across different operating conditions (e.g., cold startup vs. high-temperature operation). This prevents "pressure drift" (unexpected changes in pressure) that would cause jerky equipment movements or reduced power.
