Пружина клапана приоритета рулевого управления Caterpillar 4838013

The Steering Priority Valve Spring resides within the steering priority valve, a component responsible for directing hydraulic flow based on system demands. When multiple hydraulic functions are operating simultaneously, this valve ensures that steering always receives sufficient flow first before other circuits are supplied. The spring applies a preload force to the valve spool, helping maintain its default position until hydraulic pressure exceeds a certain threshold. As system pressure rises, the spring compresses, allowing the spool to shift and redirect flow. Attributes:• Maintains correct hydraulic flow prioritization for steering.• Assists spool movement within the priority valve.• Helps stabilize pressure differentials between circuits.Applications: The Steering Priority Valve Spring is mounted inside the steering priority valve near the hydraulic manifold block or pump outlet. Positioned where hydraulic flow is split between steering and auxiliary systems.
